Certification InformationThe MultiPro carries the following certifications:

UL Class I Division 1 Groups A,B,C,D Temp Code T4

Signal WordsThe following signal words, as defined by ANSI Z535.4-1998, are used in theMultiPro Reference Manual.

indicates an imminently hazardous situation which, if notavoided, will result in death or serious injury.

indicates a potentially hazardous situation which, if notavoided, could result in death or serious injury.

indicates a potentially hazardous situation, which if notavoided, may result in moderate or minor injury.CAUTION used without the safety alert symbol indicates a potentiallyhazardous situation which, if not avoided, may result in property damage.

Warnings and Cautions1. The MultiPro personal, portable gas detector has been designed for the

detection of dangerous atmospheric conditions. An alarm condition indicates the presence ofa potentially life-threatening hazard and should be taken very seriously.

2. In the event of an alarm condition it is important to follow establishedprocedures. The safest course of action is to immediately leave the affected area, and toreturn only after further testing determines that the area is once again safe for entry. Failureto immediately leave the area may result in serious injury or death.

3. The MultiPro must be located in a non-hazardous location whenever alkalinebatteries are removed from the alkaline battery pack. Removal of the alkaline batteries fromthe battery pack in a hazardous area may impair intrinsic safety.

4. Use only Duracell MN1500 or Ultra MX1500, Eveready Energizer E91-LR6,Eveready EN91 batteries in the alkaline battery pack. Substitution of batteries may impairintrinsic safety.

5. To reduce the risk of explosion, do not mix old or used batteries with newbatteries and do not mix batteries from different manufacturers.

6. Do not charge the MultiPro with any charger other than the BiosystemsMultiPro charger, which is Biosystems part number 54-49-103.

7. The MultiPro must be located in a non-hazardous location during the chargingcycle. Charging the MultiPro in a hazardous location may impair intrinsic safety.

8. MultiPro rechargeable battery packs are supplied with either PanasonicCGA103450 Lithium-Ion batteries. These batteries are not replaceable by the user. Therechargeable pack must be obtained from Biosystems and replaced as an assembly.

9. The accuracy of the MultiPro should be checked periodically with knownconcentration calibration gas. Failure to check accuracy can lead to inaccurate andpotentially dangerous readings.

10. Fresh air/zero calibrations may only be performed in an atmosphere that isknown to contain 20.9% oxygen, 0.0% LEL and 0 PPM toxic gas.

11. The accuracy of the MultiPro should be checked immediately following anyknown exposure to contaminants by testing with known concentration test gas before furtheruse. Failure to check accuracy can lead to inaccurate and potentially dangerous readings.

12. A sensor that cannot be calibrated or is found to be out of tolerance shouldbe replaced immediately. An instrument that fails calibration may not be used until testingwith known concentration test gas determines that accuracy has been restored, and theinstrument is once again fit for use.

13. Do not reset the calibration gas concentration unless you are using acalibration gas concentration that differs from the one that is normally supplied by Biosystemsfor use in calibrating the MultiPro.Customers are strongly urged to use only Biosystems calibration materials when calibratingthe MultiPro. Use of non-standard calibration gas and/or calibration kit components can leadto dangerously inaccurate readings and may void the standard Biosystems warranty.

14. Use of non-standard calibration gas and/or calibration kit components whencalibrating the MultiPro can lead to inaccurate and potentially dangerous readings and mayvoid the standard Biosystems warranty.Biosystems offers calibration kits and long-lasting cylinders of test gas specifically developedfor easy MultiPro calibration. Customers are strongly urged to use only Biosystemscalibration materials when calibrating the MultiPro.

15. Substitution of components may impair intrinsic safety.

16. For safety reasons this equipment must be operated and serviced by qualifiedpersonnel only. Read and understand this reference manual before operating or servicing theMultiPro.

17. A rapid up-scale reading followed by a declining or erratic reading mayindicate a hazardous combustible gas concentration that exceeds the MultiPro’s zero to 100percent LEL detection range.

18. The MultiPro is not designed for use in oxygen enriched atmospheres.

1. DescriptionThe MultiPro is a multi-sensor gas detector that canbe configured to meet a wide variety of userrequirements. This chapter provides an overview ofmany of the features of the MultiPro. More detaileddescriptions of the specific features of the MultiPro arecontained in the subsequent chapters of this manual.

MultiPro Front Face

1.1 Methods of samplingThe MultiPro may be used in either diffusion orsample-draw mode. In either mode, the gas samplemust reach the sensors for the instrument to register agas reading. The sensors are located at the bottom ofthe instrument. There are three distinct sensor portsthat allow air to reach the individual sensors.

The sensor ports must be keptfree of obstruction. Blocked sensor ports canlead to inaccurate and potentially dangerousreadings.In diffusion mode, the atmosphere being measuredreaches the sensors by diffusing through the vents atthe bottom of the instrument. Normal air movementsare enough to carry the sample to the sensors. Thesensors react quickly to changes in the concentrationsof the gases being measured. Diffusion-styleoperation monitors only the atmosphere thatimmediately surrounds the detector.The MultiPro can also be used to sample remotelocations with the hand-aspirated sample-draw kit orwith the motorized, continuous sample draw pump.During remote sampling, the gas sample is drawn intothe sensor compartment through the probe assemblyand a length of tubing. Remote sampling operationsonly monitor the atmosphere at the end of the sampledraw probe.

Use of the hand-aspirated sample draw kits iscovered in section 3.1.Use of the motorized sample draw pump iscovered in section 3.2.A detailed description of the MultiPro probeassembly is given in section 5.5.

1.2 Multi-sensor capabilityThe MultiPro can be configured to simultaneouslymonitor oxygen, carbon monoxide, hydrogen sulfideand combustible gases and vapors. All sensors arereplaceable in the field. Each of the MultiPro’s sensorchannels is configured for a specific type of sensor.Note: It is necessary to verify the accuracy of theMultiPro by calibration with known concentrationtest gas whenever a change is made to thesensors installed in the instrument.Calibration procedures are discussed in detail inChapter 4.The MultiPro uses electrochemical toxic gas sensorsthat have been designed to minimize the effects ofcommon interfering gases. These sensors provideaccurate, dependable readings for toxic gasescommonly encountered during confined space entryand other industrial applications.Different measurement units are used depending onthe gas being measured.

1.3 CalibrationThe MultiPro detector features fully automatic fresh airand span calibration.

Accuracy of the MultiPro shouldbe checked periodically with known concentrationcalibration gas. Failure to check accuracy canlead to inaccurate and potentially dangerousreadings.Calibration procedures are discussed in detail inChapter 4.Recommended calibration frequency is discussedin Appendix B.

1.4 Alarm logicMultiPro gas alarms can be adjusted with BiosystemsBioTrak Software through a PC with an IrDA port ordirectly with the MODE button (see Chapter 6 fordirect programming instructions). Alarms may be setanywhere within the nominal range of the specific

Page 9: Reference Manual MultiPro Gas Detector · 2004. 12. 20. · 1 Reference Manual MultiPro Gas Detector 651 South Main Street Middletown, CT 06457 800 711-6776 860 344-1079 Fax 860 344

sensor type. When an alarm set point is exceeded aloud audible alarm sounds, and the bright red LEDalarm lights flash.

1.4.1 Atmospheric hazard alarms MultiPro portable gas detectors

have been designed for the detection ofdeficiencies of oxygen, accumulations offlammable gases and vapors, and accumulationsof specific toxic gases. An alarm conditionindicating the presence of one or more of thesepotentially life-threatening hazards should betaken very seriously.

In the event of an alarmcondition it is important to follow establishedprocedures. The safest course of action is toimmediately leave the affected area, and to returnonly after further testing determines that the areais once again safe for entry. Failure toimmediately leave the area may result in seriousinjury or death.

A rapid up-scale readingfollowed by a declining or erratic reading mayindicate a hazardous combustible gasconcentration that exceeds the MultiPro’s zero to100 percent LEL detection range.The combustible gas alarm is activated when thepercent LEL (Lower Explosive Limit) gasconcentration exceeds any pre-set alarm level.Two oxygen alarm set points have been provided; adanger alarm for low concentrations associated withoxygen deficiency and a warning alarm for highconcentrations associated with oxygen enrichment.Four alarm set points have been provided for eachtoxic gas sensor: Warning, Danger, STEL and TWA(Time Weighted Average).Sensor Warning Danger STEL TWA

Appendix A discusses alarm levels and factorydefault alarm settings.

1.4.2 Low battery alarmsThe MultiPro may be equipped with eitherrechargeable Lithium Ion (Li-Ion) or alkaline batterypacks. Alarms will be activated whenever batteryvoltage is too low to allow the safe operation of theinstrument.The MultiPro’s initial low battery alarm occurs whenbattery voltage is reduced to 3.55 volts and isdisplayed as an empty battery cell near the center ofthe display. Once the battery voltage reaches 3.45volts, the MultiPro will automatically go into alarm,initiate the shut-down sequence and turn itself off.

For more information concerning the low batteryalarms, see section 2.4.4.

Use only Duracell MN1500 orUltra MX1500, Eveready Energizer E91-LR6,Eveready EN91 batteries. Substitution of batteriesmay impair intrinsic safety.

1.4.3 Sensor over range alarms.The MultiPro will go into alarm if a sensor is exposedto a concentration of gas that exceeds its establishedrange. In the case of an LEL reading that exceeds100% LEL, the LEL channel will be automaticallydisabled by the instrument and the instrument willremain in constant alarm until it is turned off, broughtto an area that is known to be safe, and then turnedback on. The display will show “OL” in place of thesensor reading for any channel that has gone into overrange alarm.See section 2.4.5 for further details on sensor overrange alarms.A sensor range chart is provided in Appendix C.

In the event of an LEL overrangealarm the MultiPro must be turned off, brought toan area that is known to be safe and then turnedon again to reset the alarm.

1.4.4 LEL response failure due to lack of O2alarm

The MultiPro features automatic warning against LELsensor response failure due to lack of oxygen. Seesection 2.4.7 for details.

1.4.5 Security beep/flashThe MultiPro includes a security beep function that isdesigned to notify the user that the instrument ispowered up and running. Once enabled the MultiProwill emit a short audible beep and give a short flash onthe LED at a user-defined interval. The securitybeep/flash function may be enabled and the intervalmay be changed with BioTrak software or directly withthe MODE button (see Chapter 6 for directprogramming instructions).

1.4.6 Latching peak alarmsThe MultiPro’s alarms are self-resetting unless thealarm latch is enabled. With the MultiPro’s alarmlatch enabled, the audible and visible alarms willcontinue to sound after the atmospheric hazard hascleared. To reset the alarms, simply press the MODEbutton. If the alarm latch is disabled and the alarmcondition is no longer present, the instrumentautomatically returns to normal operation, and thevisible and audible alarms cease without further inputfrom the user.

1.4.7 Fault detectionMultiPro software includes a number of additionalalarms designed to ensure the proper operation of theinstrument. When the MultiPro detects that anelectronic fault or failure condition has occurred, theproper audible and visible alarms are activated and anexplanatory message or message code is displayed.

The MultiPro is designed todetect potentially life threatening atmosphericconditions. Any alarm condition should be takenseriously. The safest course of action is toimmediately leave the affected area, and returnonly after further testing determines that the areais once again safe for entry.

1.5 Other electronic safeguardsSeveral automatic programs prevent tampering andmisuse of the MultiPro by unauthorized persons.Each time the detector is turned on, the MultiProautomatically tests the LED alarm light, audible alarm,internal memory and pump status (if so equipped).The battery is monitored continuously for propervoltage. The MultiPro also monitors the connection ofsensors that are currently installed. The detection ofany electronic faults causes the activation of theaudible and visible alarms and causes the display ofthe appropriate explanatory message.

1.5.1 HeartbeatAt the center of the display is a heart symbol that willblink every few seconds to show that the instrument isfunctioning normally.

1.6 SensorsThe MultiPro can be configured to simultaneouslymonitor oxygen, carbon monoxide, hydrogen sulfideand combustible gases and vapors. The sensorconfiguration of the MultiPro may be specified at thetime of purchase, or changed in the field byappropriately trained personnel.Replacement sensor part numbers and sensorranges are given in Appendix B.Sensor cross-sensitivity figures are given inAppendix C.

A sensor that cannot becalibrated or is found to be out of tolerance mustbe replaced immediately. An instrument that failscalibration may not be used until testing withknown concentration test gas determines thataccuracy has been restored, and the instrument isonce again fit for use.Calibration procedures are discussed in detail inChapter 4.

1.7 Optional sample draw pumpA motorized sample-draw pump is available for theMultiPro for situations requiring continuous "handsfree" remote monitoring.

The pump is Biosystems part number 54-49-102.The pump contains a pressure sensor that detectsrestrictions in airflow caused by water or otherobstructions being drawn into the unit and immediatelyacts to turn the pump off in order to protect thesensors, pump, and other MultiPro components fromdamage.

MultiPro with pump attachedPump status is continuously monitored by the MultiPromicroprocessor. When the pump is active andfunctioning properly, “PUMP” is displayed near thecenter of the LCD display. Low flow or other pumpfault conditions activate audible and visible alarmsand cause the display of the appropriate explanatorymessage.

1.8 Data storageThe MultiPro includes a black box data recorder andan event logger as standard features.

1.8.1 Black box data recorderA black box data recorder is a standard feature in theMultiPro. The “black box” is continually in operationwhether the user is aware of it or not. The black boxstores important information such as gas readings,turn-on times, turn-off times, temperatures, batteryconditions, the most recent calibration date andsettings, types of sensors currently installed, sensorserial numbers, warranty expiration and service duedates, and current alarm settings.There is a finite amount of memory storage availablein the black box data recorder. Once the memory is“full”, the MultiPro will begin to write the new data overthe oldest data. The black box data recorder will storeapproximately 41 hours of data in one-minuteincrements before it begins to write new data over theoldest data. In this way, the newest data is alwaysconserved.To extract the information from the black box datarecorder, the MultiPro must be returned toBiosystems. Once the data is downloaded from theinstrument, a report will be generated. The unit andthe report will then be returned to the user. Simply

call Biosystems Service Department to obtain a returnauthorization number. There is no charge for thedownloading service, but the user is responsible forany freight charges incurred.The “black box” data recorder in the MultiPro can beupgraded to a fully enabled datalogger at any time.All that is required is the activation code thatcorresponds to the serial number of the MultiPro.

1.8.2 Event loggerThe event logger in the MultiPro stores dataassociated with alarm conditions. Each (alarm) eventincludes the following data for each of the installedsensors: Sensor type, the Max reading, the averagereading as well as the start time, end time andduration of the event. The MultiPro stores the 20most recent events. Once 20 events have beenstored, the MultiPro will begin to systematicallyoverwrite the data from the oldest event in memorywith data from new events. One event may be acombination of different alarms occurringsimultaneously or in immediate succession. Theevent logger may be downloaded using Biosystems'BioTrak software. The PC must be equipped withIrDA to provide a connection.

readings before the oldest data is overwritten by newdata.The time will then be shown followed by the date:

The instrument will display “Self Test” as it performs afew operational checks. During the self-test, theMultiPro tests for installed sensors, performs a systemmemory check and tests to see if a motorized pump isattached to the instrument. If a pump is detected, itwill be briefly activated during the self-test. Fordetails on start up procedures for pump-equippedMultiPro instruments see section 2.1.1 below.

For instructions on changing the time and datewith the MODE button, see section 6 below.The instrument temperature will then be shown.

The warning alarm levels screen will then be shownfollowed by the danger, STEL and TWA alarm levelsscreens.

For more information concerning STEL and TWAalarms, see sections 2.4.3 and 2.4.4.After the alarm screens, The calibration due screenwill be shown with the number of days until the nextcalibration and proceed to the current gas readingsscreen. The screen will also indicate if calibration is

or

Following the calibration status screen, the MultiProwill proceed to the current gas readings screen.

2.1.1 Start up with pumpMultiPro instruments that are equipped with a built-inmotorized sample draw pump will have a slightlylonger start up sequence. After the calibration duescreen, the MultiPro will prompt you to leak test thepump.Note: The sample probe assembly must beattached when the pump is started.

Block the sampling inlet by placing a finger over theend of the sample probe assembly. Once the MultiProrecognizes that the test is passed, it will instruct you toremove the blockage.

Once the blockage is removed, the MultiPro willproceed to the current gas readings screen.If the instrument is unable to detect the vacuumresulting from the pump blockage, the test will fail andyou will be directed to remove the pump.

For information concerning proper attachment of thesample probe assembly to pump-equipped MultiProinstruments, see section 3.1.2.2 Operating LogicOnce the MultiPro has completed the start upsequence, the current gas readings screen will beshown.

At the center of the display is a heartbeat that will“beat” every few seconds to show that the instrumentis functioning normally.When a sensor is not detected, the reading in thedesignated sensor channel will be blank. In theexample below, the LEL sensor has not beendetected.

If the MultiPro recognizes that the pump is attached,“Pump” will be displayed in the current gas readingsscreen

button a second time. Press the MODE button a thirdtime to view the Short Term Exposure Limit (STEL)readings. Press the MODE button again to view theTime Weighted Averages (TWA) for the operatingsession.Note: The MultiPro must be in continuousoperation for at least 15 minutes before it will beable to calculate the TWA values. For the first 15minutes of any operating session, the screen willshow the length of time that the instrument hasbeen operating instead of the TWA values.

2.3 Turning the MultiPro OffTo turn the MultiPro off, press and hold the MODEbutton until the display reads “Release Button”.“Please wait” will be shown briefly and display will goblank.

2.4 AlarmsThe MultiPro is configured with a series of alarms thatare designed to warn the user of dangerousconditions.

The MultiPro is designed todetect potentially life threatening atmosphericconditions. Any alarm condition should be takenseriously. The safest course of action is toimmediately leave the affected area, and returnonly after further testing determines that the areais once again safe for entry.

2.4.1 Warning AlarmsWarning alarms indicate adangerous atmosphericcondition that has not yetrisen to the level necessaryto initiate the danger alarms.Warning alarm levels areshown during the start upsequence.

2.4.2 Danger AlarmsDanger alarms indicate asignificantly hazardouscondition. As is the casewith the warning alarms,the danger alarms areshown in the start upsequence.

2.4.3 STEL AlarmsSTEL (Short TermExposure Limit) alarmvalues represent theaverage concentration ofinstrument readings for thetarget gas for the mostrecently completed 15minutes of operation. The default STEL alarm levelfor the MultiPro CO sensor is 100PPM. The defaultSTEL value for the MultiPro H2S sensor is 15PPM.

2.4.4 TWA AlarmsTWA (Time WeightedAverage) values arecalculated by taking the sumof exposure to a particulartoxic gas in the currentoperating session in terms ofparts-per-million-hours anddividing by an eight-hour period. The default TWAalarm level for the MultiPro CO sensor is 35PPM.The default TWA value for the MultiPro H2S sensor is10PPM.

2.4.5 Low battery alarmsWhen battery voltage is reduced to approximately3.55 volts, the battery icon on the LCD will appearempty, which means that a low battery conditionexists.

If the battery icon is empty, leave the areaimmediately. If the MultiPro is equipped with analkaline battery pack, proceed to an area that is knownto be safe area (containing 20.9% oxygen, 0% LELand 0 PPM toxic gases) and change the batteries. Ifthe MultiPro is equipped with a Li-Ion battery pack,proceed to an area that is known to be safe andrecharge the battery pack.When battery voltage reaches approximately 3.45volts, the MultiPro is no longer safe to use with thecurrent battery pack. The screen will briefly display a“0-BAT” warning and begin a ten-second countdown.At the end of the countdown, the MultiPro will turnitself off.

Alkaline battery replacement and Li-Ion batterycharging instructions are contained in section 5.2and 5.3.

The MultiPro must be located ina non-hazardous location during the chargingcycle. Charging the MultiPro in a hazardouslocation may impair intrinsic safety.

The MultiPro must be located ina non-hazardous location whenever alkalinebatteries are removed from the alkaline battery

pack. Removal of the alkaline batteries from thebattery pack in a hazardous area may impairintrinsic safety.CAUTION Always turn the MultiPro off prior toremoving the battery pack. Removal of the batterypack with the instrument turned on may causecorruption of stored data in the MultiPro.

2.4.6 Sensor over range alarmsThe MultiPro will go into alarm if a sensor is exposedto a concentration of gas that exceeds its establishedrange. In the case of an LEL reading that exceeds100% LEL, the LEL channel will be automaticallydisabled by the instrument and the alarm will latch(remain on) until the instrument is turned off. TheMultiPro must be turned off, brought to an area that isknown to be safe (containing 20.9% oxygen, 0% LELand 0 PPM toxic gases), and then turned back on.The display will show “---“ and “OL” alternately inplace of the sensor reading for any channel that hasgone into over range alarm.

A combustible sensoroverrange alarm indicates a potentially explosiveatmosphere. Failure to leave the area immediatelymay result in serious injury or death!

In the event of an LELoverrange alarm the MultiPro must be turned off,brought to an area that is known to be safe(containing 20.9% oxygen, 0% LEL and 0 PPMtoxic gases), and then turned on again to reset thealarm.

2.4.7 LEL failure due to lack of oxygen alarmThe LEL sensor in the MultiPro requires a certainamount of oxygen to function properly. When oxygenlevels fall below 11% by volume, the MultiPro willshow “---“ in place of the LEL reading and display“O2”, “too” and “Lo” in successive screens in thelocation typically used for the LEL reading.

2.5 PC connection via infrared portMultiPro instruments that are equipped with a fullyenabled datalogger can be downloaded to a PC usingBiosystems BioTrak or IQ software through theMultiPro’s infrared port. For the location of theinfrared port, see figure 1.9 above.1. With the MultiPro

turned off, hold theMODE button downuntil four beeps areheard. Depending onthe software version,this will normally takebetween 10 and 20seconds. “PCConnect” will be shown once the infrared port hasbeen activated.

2. Align the infrared port on the MultiPro with thePC’s infrared port to complete the connection.

Note: For further instructions concerning thedownload procedure for the MultiPro, see theBioTrak or IQ System manual as appropriate.

2.6 Error MessagesThe MultiPro will display error messages when itdetects certain problems during operation.

If the MultiPro displays an error message, contactBiosystems for further instructions.

3. SamplingThe MultiPro may beused in either diffusionor sample-draw mode.In either mode, the gassample must reach thesensors for theinstrument to register agas reading. Thesensors are located atthe bottom of theinstrument.

The sensor ports must be keptfree of obstruction. Blocked sensor ports canlead to inaccurate and potentially dangerousreadings.In diffusion mode, the atmosphere being measuredreaches the sensors by diffusing through vents at thebottom of the instrument. Normal air movements areenough to carry the sample to the sensors. Thesensors react quickly to changes in the concentrationsof the gases being measured. Diffusion-styleoperation monitors only the atmosphere thatimmediately surrounds the detector.The MultiPro can also be used to sample remotelocations with either the hand-aspirated sample-drawkit, or with the motorized sample draw pump. Duringremote sampling, the gas sample is drawn into thesensor compartment through the probe assembly anda length of tubing.

3.1 Manual sample draw kitThe manual sample draw kit is comprised of a sampledraw probe, 2 sections of tubing, a squeeze bulb andan adapter that is used to connect the sample drawaccessories system to the MultiPro.

Note: The maximum amount of tubing that can beused with the manual sample draw kit is 50 feet.

3.1.1 Manual sample draw kit usageTo use the manual sample draw kit:1. Connect the short section of hose that comes off

the squeeze bulb to the sample draw adapter.2. To test the seals in the sample draw system,

cover the end of the sample draw probe with afinger, and squeeze theaspirator bulb. If there areno leaks in the sampledraw kit components, thebulb should stay deflatedfor a few seconds.

3. Secure the calibrationadapter (with the sampledraw assembly attached)to the MultiPro by inserting

Page 17: Reference Manual MultiPro Gas Detector · 2004. 12. 20. · 1 Reference Manual MultiPro Gas Detector 651 South Main Street Middletown, CT 06457 800 711-6776 860 344-1079 Fax 860 344

16

the tab and tightening the knurled screw into thebrass nut at the bottom of the adapter.

4. Insert the end of the sample probe into thelocation to be sampled.

5. Squeeze the aspirator bulb to draw the samplefrom the remote location to the sensorcompartment.

To ensure accurate readings while using themanual sample draw kit, it is necessary tosqueeze the bulb once for every one foot ofsampling hose for the sample to first reach thesensors, and then to continue squeezing thebulb once per second for an additional 45seconds or until readings stabilize. As anexample, if 10 feet of tubing is used, it will benecessary to draw the sample in by squeezingthe bulb continuously for a minimum of 55seconds or until readings stabilize.

6. Note the gas measurement readings.CAUTION: Hand aspirated remote samplingonly provides continuous gas readings for thearea in which the probe is located while the bulbis being continuously squeezed. Each time areading is desired, it is necessary to squeeze thebulb a sufficient number of times to bring a freshsample to the sensor compartment.

3.2 Motorized sample draw pumpA motorized sample-draw pump is available for theMultiPro for situations requiring continuous "handsfree" remote monitoring. Use of the motorized sampledraw pump allows the MultiPro to continuouslymonitor remote locations. The pump is powered bythe MultiPro battery. When the pump is attached tothe instrument, “PUMP” will be shown on the display inthe current gas readings screen.

Note: The maximum amount of tubing that can beused with the motorized sample draw pump is 50feet.

To ensure accurate readings while using thecontinuous sample pump, it is necessary to allowthe pump to draw the sample for one second forevery one foot of sampling hose plus anadditional 45 seconds or until readings stabilize.For example, with 10’ of tubing, it will benecessary to allow a minimum of 55 seconds for

the sample to be drawn into the sensor chamberand for the readings to stabilize.MultiPro instruments are designed to automaticallyrecognize the pump whenever it is attached to theinstrument. If the pump is attached when the MultiProis turned off, the instrument will automatically initiatethe pump start up sequence when the instrument isturned on. If the pump is attached while theinstrument is running, the MultiPro will automaticallyinitiate the pump test sequence before returning to thecurrent gas readings screen.

3.2.1 Starting the motorized sample pumpFirst attach the probeand tubing to the pump,then secure the pump(with the sample drawassembly attached) tothe MultiPro by insertingthe tab and tighteningthe knurled screw on theadapter into theinstrument casing.Note: The sample probe assembly must beattached to the pump when when the pump isattached to the instrument.Once the pump is recognized, the pump testsequence will be initiated automatically.

Block the sampling inlet by placing a finger over theend of the sample probe assembly. Once theblockage is detected, the MultiPro will indicate that thetest has been passed and instruct you to remove theblockage before proceeding to the current gasreadings screen.

If the instrument is unable to detect the vacuumresulting from the pump blockage within 30 seconds,the test will fail, the instrument will go into alarm andyou will be directed to remove the pump.

Page 18: Reference Manual MultiPro Gas Detector · 2004. 12. 20. · 1 Reference Manual MultiPro Gas Detector 651 South Main Street Middletown, CT 06457 800 711-6776 860 344-1079 Fax 860 344

Remove the pump and press the MODE button toresume diffusion operation.

3.2.2 Turning off the pumpTo turn off the pump, simply remove the pump fromthe bottom of the instrument.

3.2.3 Pump low flow alarmThe MultiPro contains a pressure sensor thatcontinuously monitors for restrictions in airflow causedby water or other fluids being drawn into the unit andimmediately acts to turn the pump off in order toprotect the sensors, pump, and other MultiProcomponents from damage.CAUTION: Never perform remote sampling withthe MultiPro without the sample probe assembly.The sample probe handle contains replaceablefilters designed to block moisture and removeparticulate contaminants. If the pump is operatedwithout the probe assembly in place,contaminants may cause damage to the pump,sensors and internal components of the MultiProWhen the pump is active and functioning properly,“PUMP” is displayed near the center of the LCDdisplay. Low flow or other pump fault conditionsactivate audible and visible alarms and cause thedisplay of the appropriate explanatory message.

The pressure sensor in the sample draw pump isdesigned to detect pressure changes while thesample-draw probe is being held in a vertical position.If the probe is held horizontally or at a low angle whileinserted into a fluid, a pressure drop sufficient tocause the pump to shut down may not be generated,and water could be drawn into the pump assemblycausing damage to the pump, sensors and internalcomponents of the MultiPro.CAUTION: Insertion of the sample draw tubeinto a fluid horizontally or at a low angle may leadto water ingress and may cause damage to thesensors and internal components of the MultiPro.

If the MultiPro determines that a significant pressurechange has occurred, it will go into alarm and notifythe user that there is a blockage of the pump. Thedisplay will alternate between the following twoscreens.

Remove the blockage and press the MODE button toacknowledge the alarm and resume sampling.

3.3 Sample draw probeThe MultiPro’s sample draw probe is the standardprobe assembly from Biosystems. The sample probehandle contains moisture barrier and particulate filtersdesigned to remove contaminants that mightotherwise harm the instrument.Particulate contaminants are removed by means of acellulose filter. The hydrophobic filter includes aTeflon barrier which blocks the flow of moisture aswell as any remaining particulate contaminants.Sample probe filters should be replaced whenevervisibly discolored due to contamination. See section5.5.1 for a probe diagram and a list of availablesample probe filter replacement kits.

4. CalibrationThe accuracy of the MultiPro should be verified on aregular basis. Verification can be as simple asperforming a bump test, which is described below insection 4.1. If exposure to fresh air yields an oxygenreading of less than 20.7% or greater than 21.1% or atoxic or LEL sensor reading of anything other than 0,then a Fresh Air/Zero Calibration should be performedas described in section 4.2. If exposure to a knownconcentration calibration gas shows the LEL or toxicsensors to be off by more than 10% (either higher orlower), then the Span Calibration should be performedas described in section 4.3.For Biosystems’ official recommendationsconcerning calibration frequency, see AppendixB.

4.1 Functional (Bump) testingThe accuracy of the MultiPro may be verified at anytime by a simple functional (bump) test.To perform a functional (bump) test, do the following:1. Turn the MultiPro on and wait at least three

minutes to allow the readings to fully stabilize. Ifany of the sensors have just been replaced, thenew sensor(s) must be allowed to stabilize prior touse. See section 5.4 for further details.

2. Make sure the instrument is located in fresh air.3. Verify that the current gas readings match the

concentrations present in fresh air. The oxygen(O2) sensor should read 20.9% (+/-0.2%). Thereadings for the LEL sensor should be 0% LELand toxic sensors should read 0 parts-per-million(PPM) in fresh air. If the readings deviate fromthe expected levels in a fresh air environment,proceed to section 4.2 and perform the fresh aircalibration adjustment. Once the fresh aircalibration adjustment has been performed,proceed to step 4.

4. Attach the calibration adapter and connect thecalibration cylinder to the MultiPro as shown infigure 4.1. Flow gas to the sensors.

5. Wait for the readings to stabilize. (Forty-fiveseconds to one minute is usually sufficient.)

6. Note the readings. Toxic and LEL sensorreadings are considered accurate in a bump test ifthey are within 10% (higher or lower) of theexpected reading. If the readings are accurate,then the instrument may be used without furtheradjustment. If any of the readings are off by morethan 10% proceed to section 4.3 and perform thespan calibration.Biosystems multi-calibration gas mixtures typicallycontain approximately 18% oxygen. During thespan calibration function the oxygen sensor shouldread within 0.5% of the level given on thecalibration cylinder.

Figure 4.1 Bump Test and Span Calibration set up

4.2 Fresh Air/Zero Calibration Fresh air/zero calibrations may

only be performed in an atmosphere that is knownto contain 20.9% oxygen, 0.0% LEL and 0 PPMtoxic gas.To initiate the fresh air/zero calibration:1. Press the MODE button three times within two

seconds to begin the fresh air/zero calibrationsequence. The MultiPro will briefly display AUTOCAL and then begin a 5-second countdown.

2. Press the MODE button before the end of the 5-second countdown to begin the fresh air/zerocalibration. The fresh air/zero calibration isinitiated when the MultiPro alternates between thefollowing two screens:

3. The fresh air/zero calibration is complete when the

instrument begins another 5-second countdownfor the span calibration. If span calibration is notrequired, allow the countdown to reach 0 withoutpressing the MODE button.

4.2.1 Fresh air/zero calibration failureIn the event of a fresh air/zero calibration failure, thealarms will be activated and the instrument will displaythe following screen. Note that the sensor(s) that failthe zero calibration are shown (in this case, CO)

After 3 seconds, the MultiPro will return to the currentgas readings screen and the visual and audible alarmswill cease.When fresh air/zero calibration is due, the MultiPro’sdisplay will show the warning symbol whileintermittently displaying the 0-CAL icon in the gasreadings screen until a successful fresh air calibrationis performed. If a specific sensor has failed the freshair/zero calibration, it will be displayed with the 0-Calicon.

If a successful fresh air / zero calibration is notperformed prior to instrument shut down, the MultiProwill note that Fresh Air Calibration is due duringinstrument start up.Possible causes and solutions1. The atmosphere in which the instrument is located

is contaminated (or was contaminated at the timethe instrument was last fresh air calibrated.

2. A new sensor has just been installed.3. Instrument has been dropped or banged since last

turned on.4. There has been a significant change in

temperature since the instrument was last used.Recommended action:Take the instrument to fresh air and allow readings tostabilize. Perform the fresh air/zero adjustment again.

If the manual fresh air/zero procedure fails to correctthe problem, perform the manual fresh air / zerocalibration procedure as described in section 4.2.2below.

4.2.2 Manual fresh air / zero calibrationThe MultiPro includes safeguards to prevent fresh aircalibration in contaminated environments. If thestandard fresh air / zero calibration fails a secondtime, the instrument may be “forced” to accept thefresh air calibration by performing the manual fresh air/ zero calibration.

Fresh air/zero calibrations mayonly be performed in an atmosphere that is knownto contain 20.9% oxygen, 0.0% LEL and 0 PPMtoxic gas.1. Initiate the standard fresh air / zero calibration

sequence by pressing the MODE button threetimes in rapid succession. The 5-secondcountdown will begin.

2. Press the MODE button before the end of the 5-second countdown and continue to hold theMODE button. As in the standard fresh air /zerocalibration, the MultiPro will alternate between thefollowing two screens:

3. The fresh air/zero calibration is complete when the

instrument begins another 5-second countdownfor the span calibration. If span calibration is notrequired, allow the countdown to reach 0 withoutpressing the MODE button.

If the MultiPro still fails to calibrate after attemptingthe manual fresh air / zero calibration, callBiosystems.

4.3 Span CalibrationOnce the fresh air / zero calibration has beensuccessfully completed, the MultiPro will automaticallyproceed to the automatic span calibration countdownscreen. The instrument is ready for span calibrationwhen the following screen is shown.

Page 21: Reference Manual MultiPro Gas Detector · 2004. 12. 20. · 1 Reference Manual MultiPro Gas Detector 651 South Main Street Middletown, CT 06457 800 711-6776 860 344-1079 Fax 860 344

Press the MODE button before the countdown iscomplete to initiate the span calibration. The screenwill immediately show “APPLY GAS” and then list thesensors for calibration and the expected levels ofcalibration gas.

Note: Biosystems recommends the use of multi-component calibration gas for calibrating theMultiPro.Apply calibration gas as shown above in figure 4.1.The readout will change to a numerical display almostimmediately and will continue to display the currentreadings.

The oxygen sensor is fully calibrated during the freshair calibration function, so the sensor is not shownduring the span calibration.When the reading stabilize, the MultiPro will completethe calibration and show the calibration values.

Once the calibration of all sensors is successfullycompleted, the MultiPro will briefly show themaximum adjustment values screen.

The maximum adjustment values for the LEL andtoxic sensors give an indication of the remainingsensitivity of the sensors. As sensitivity decreases,the maximum possible adjustment will decrease to

approach the expected concentration of the calibrationgas.Note: Once the calibration cycle is completed, theMultiPro will automatically turn itself off.Disconnect the calibration assembly prior toturning the instrument back on.

4.3.1 Span calibration failureWhen there is a span calibration failure, the displaywill show CAL Error and display the sensor whosecalibration has failed.

If the instrument fails to recognize the correct type orconcentration of calibration gas, it will show “no GAS”.

When span calibration is due, the MultiPro’s displaywill show the warning symbol while intermittentlydisplaying the calibration bottle in the gas readingsscreen.

The MultiPro will also display a “Needs Cal” messagefor any sensors that are currently due for calibrationduring instrument start-up.Possible causes of span calibration failure andremedies:1. Empty calibration gas cylinder. Verify that there is

calibration gas in the cylinder.2. Expired calibration gas cylinder. Verify that the

expiration date on the cylinder has not passed.3. Calibration gas setting does not correspond to

calibration gas concentration. The defaultcalibration gas settings are 50% LEL, 50PPM COand 25PPM H2S. If the values on the calibrationcylinder are different from these values, theMultiPro’s calibration gas settings must be

Page 22: Reference Manual MultiPro Gas Detector · 2004. 12. 20. · 1 Reference Manual MultiPro Gas Detector 651 South Main Street Middletown, CT 06457 800 711-6776 860 344-1079 Fax 860 344

21

changed to match the new values. Changing thecalibration gas settings requires the use of theMultiPro programming software, which is availableseparately.

4. LEL only: Type of calibration gas (standard) haschanged significantly. LEL calibration gas may bebased on several different response standards,methane, propane and pentane are the mostcommon. If using a new cylinder of calibrationgas, make sure that the type and amount ofcombustible gas is identical to that of the previousbottle. Biosystems offers calibration gases inMethane, Propane Equivalent and PentaneEquivalent.

5. Dead sensor. Replace sensor.6. Instrument problem. Return the instrument to

Biosystems. Call the phone number on the frontof this manual.

5. Maintenance To prevent ignition of

flammable or combustible atmospheres,disconnect power before servicing any parts inthe MultiPro.

5.1 BatteriesThe MultiPro is powered by interchangeable alkalineand Li-Ion rechargeable battery packs.

Note: The calibration adapter or sample drawadapter must be removed from the MultiPro priorto removing the battery pack.To remove the battery pack first loosen the top centerscrew on the back of the instrument, then gently prythe two clasps at the top of the instrument open whilesimultaneously pulling the back cover plate away fromthe main instrument housing. Since the battery packis housed in the back cover plate, this willautomatically disconnect power from the instrument.

CAUTION Always turn the MultiPro off prior toremoving the battery pack. Removal of the batterypack with the instrument turned on may causecorruption of stored data in the MultiPro.

5.2 Replacing alkaline batteriesThe alkaline battery pack contains three AA alkalinebatteries.

The MultiPro must be located ina non-hazardous location whenever alkalinebatteries are removed from the alkaline batterypack. Removal of the alkaline batteries from thebattery pack in a hazardous area may impairintrinsic safety.

Use only Duracell MN1500 orUltra MX1500, Eveready Energizer E91-LR6,Eveready EN91 batteries. Substitution of batteriesmay impair intrinsic safety.

To replace the alkaline batteries:1. Remove the battery pack from the MultiPro as

discussed in above in section 5.1.2. Remove the three alkaline

batteries and replace them.Be sure to align the positiveand negative ends inaccordance with thediagram under each battery.

3. Reinstall the back coverplate that was removed instep 2.

4. Return the battery pack tothe MultiPro and re-tightenthe top center screw. TheMultiPro will automatically turn itself on once thebattery pack is reinstalled.

5.3 Maintaining Li-Ion battery packsThe MultiPro may be equipped with a rechargeable Li-Ion (Lithium Ion) battery pack.

5.3.1 Storage guidelines for the Li-Ionbattery

Never store Li-Ion -version MultiPro instruments attemperatures above 30 degrees Celsius (86 degreesFahrenheit). Li-Ion batteries may suffer deteriorationresulting in damage to the internal components whenstored at high temperatures. The battery may beirretrievably damaged resulting in reduced batterycapacity and voltage.Biosystems recommends leaving MultiPro instrumentswith Li-Ion rechargeable batteries on the charger whennot in use.

5.3.2 Charging guidelines for Li-Ion batteryThe Li-Ion battery in the MultiPro should never becharged at temperatures lower than 5 degrees Celsius(40 degrees Fahrenheit) or higher than 30 degreesCelsius (86 degrees Fahrenheit. Charging attemperature extremes can permanently damage theMultiPro Li-Ion battery.

The MultiPro must be located ina non-hazardous location during the chargingcycle. Charging the MultiPro in a hazardouslocation may impair intrinsic safety.

5.3.3 Charging procedure for Li-Ion battery Do not charge the MultiPro with

any charger other than the Biosystems MultiProcharger, which is Biosystems part number 54-49-103.1. Verify that the instrument is turned off. (If it is not,

press the MODE button for three seconds until themessage "Release Button" appears.)

2. Plug the power supply in. The red LED is labeled“Power” and will be lit whenever the charger isplugged into a power source.

3. Insert the MultiPro into the charging cradle bottomside down with the display facing forward. Thegreen LED on the charger is labeled “Charge” andwill be lit while the battery is charging.

4. When the battery is fully charged, the “Charge”LED will go out.

See section 5.3.4 for battery troubleshootingguidelines.

5.3.4 Charging with the pump attached.To charge the MultiPro battery withthe pump installed on theinstrument, a spacer is used in thecharger base to make up thedifference between the size of theMultiPro and the size of the pump,which is slightly smaller. Thespacer should be oriented with thegap towards the front of thecharger, and with the guide pinsfacing down towards the charger asshown in the illustration at right.Once the spacer has been inserted,the MultiPro with pump may becharged according to the instructiongiven in section 5.3.3 above.

5.3.5 Battery troubleshootingIf the green “Charge” LED on the charger fails to lightwhen the MultiPro with Li-Ion battery pack is placed inthe charger, remove the instrument from the chargerand press the MODE button to attempt to start theinstrument.If the battery has been inserted into the chargerwithout the instrument, return it to the instrument priorto attempting the restart.1. If the MultiPro starts and the battery icon shows all

three bars, then the battery is fully charged andmay be used. In this case, the charger hasrecognized that the battery is charged and will notcharge it any further.

2. If the MultiPro fails to turn on, then the batterymay be severely discharged and should bereturned to the charger. The charger will thenbegin a very slow recharge in order to protect thebattery. The green “Charge” LED may not be litduring the first four hours of the slow recharge. Ifthe “Charge” LED has still not been lit after fourhours, the battery pack or charger is probablydamaged.

3. If the MultiPro starts and any battery level otherthan full is indicated, then either the battery isdamaged or the charger is damaged. CallBiosystems for further instructions.

5.4 Sensor installationThe sensors in the MultiPro are located in a ventedcompartment at the bottom of the instrument.To install a sensor:1. Turn the MultiPro off.2. Remove the battery pack as described in section

5.1. This will automatically disconnect power fromthe instrument.

3. Remove thefour screwsshown and pullthe entire mainboardassembly freefrom theinstrumenthousing.

4. Gently removethe sensor that is to be replaced.

5. Insert the new sensor into the appropriate locationon the sensor interface board.

6. Reinstall the main board assembly that wasremoved in step three and reinstall the fourscrews.

7. Reattach the battery pack.8. New sensors must be allowed to stabilize prior to

use according to the following schedule. Thedetector must be powered off and a functionalbattery pack must be installed for the sensor tostabilize.

Sensor Stabilization PeriodOxygen (O2) 1 hour

LEL noneCO 15 minutesH2S 15 minutes

Note: Steps 9 and 10 assume that the sensorstabilization period has passed.9. If an oxygen sensor was replaced, perform the

Fresh Air/Zero calibration as discussed in section4.2.

10. If a combustible (LEL) or a toxic sensor has beenreplaced, perform both the Fresh Air/Zerocalibration and the Span calibration as discussedin sections 4.2 and 4.3.

Note: Sensor channels in the MultiPro arespecific to the type of sensor that occupies thechannel. When replacing sensors, be sure toreplace one sensor with another of the same type.

5.5 Sample probe assemblyThe MultiPro’s sample draw probe is the standardprobe assembly from Biosystems. The illustrationbelow gives a breakdown of all parts in the sampledraw probe with part numbers. The sample probe

handle contains moisture barrier and particulate filtersdesigned to remove contaminants that mightotherwise harm the instrument.CAUTION: Never perform remote samplingwithout the sample probe and hose assembly.The sample probe handle contains replaceablefilters designed to block moisture and removeparticulate contaminants. If the pump is operatedwithout the probe assembly in place,contaminants may cause damage to the pump,sensors and internal components of the MultiPro.Particulate contaminants are removed by means of acellulose filter. The hydrophobic filter includes aTeflon barrier which blocks the flow of moisture aswell as any remaining particulate contaminants.Sample probe filters should be replaced whenevervisibly discolored due to contamination.

5.5.1 Changing sample probe filtersThe threaded sample probe handle is to provideaccess to the filters. The particulate filter is held inplace by means of a clear filter cup. To replace theparticulate filter, remove the old filter and cup, insert anew filter into the cup, and slide the cup back intoplace in the probe handle. The hydrophobic barrierfilter fits into a socket in the rear section of the probehandle. (The narrow end of the hydrophobic barrierfilter is inserted towards the rear of the handle.)To avoid accidentally introducing particulatecontaminants into the system, turn the sample probeupside-down prior to removing either the hydrophobicfilter or the particulate filter.

5.5.2 Changing sample probe tubes (wands)The standard 11.5” long butyrate probe tube is held inplace by means of a hex-nut compression fitting andcompression sleeve. The standard probe tube isdesigned to be easily interchangeable with othercustom length sections of 1/4” OD tubing, or probetubes made of other materials (such as stainlesssteel).Probe tubes are exchanged by loosening the hex-nutcompression fitting, removing the old tube, sliding thecompression sleeve into place around the new tube,inserting the new tube into the probe handle, thenreplacing and tightening the hex-nut.Note: The sample probe must be checked forleakage (as discussed in Section 3.1.1) wheneverfilters or probe tubes are exchanged or replacedbefore being returned to service.

5.6 MultiPro Pump MaintenanceMultiPro pumps are fairly maintenance free with theexception of the replacement of the pump filters on aregular basis.

5.6.1 Replacing pump filters1. Remove the two screws that hold the inlet port to

the pump.2. Gently pull the dust filter holder free of the pump3. Remove and replace the dust filter that is located

in the holder.4. The hydrophobic filter is located beneath the inlet

port in the pump housing. Use a smallscrewdriver or other object to punch through thefilter and remove it. The gasket that sits betweenthe inlet port and the filter should come out withthe filter.

5. Place the new hydrophobic filter filter side down inplace of the one removed in step 4. The gasketshould be located on top of the filter and should sitagainst the dust filter holder, which will bereinstalled in step 6.

6. Replace the dust filter holder (which now has anew filter in it) and secure it with the two screwsremoved in step 1.

AppendicesAppendix A Toxic gas measurement –Warning, Danger, STEL and TWA alarmsMany toxic substances are commonly encountered in industry.The presence of toxic substances may be due to materials beingstored or used, the work being performed, or may be generatedby natural processes. Exposure to toxic substances can producedisease, bodily injury, or death in unprotected workers.It is important to determine the amounts of any toxic materialspotentially present in the workplace. The amounts of toxicmaterials potentially present will affect the procedures andpersonal protective equipment that must be used. The safestcourse of action is to eliminate or permanently control hazardsthrough engineering, workplace controls, ventilation, or other safetyprocedures. Unprotected workers may not be exposed to levels oftoxic contaminants that exceed Permissible Exposure Limit (PEL)concentrations. Ongoing monitoring is necessary to insure thatexposure levels have not changed in a way that requires the use ofdifferent or more rigorous procedures or equipment.Airborne toxic substances are typically classified on the basis oftheir ability to produce physiological effects on exposed workers.Toxic substances tend to produce symptoms in two time frames.Higher levels of exposure tend to produce immediate (acute)effects, while lower levels of long-term (chronic) exposure may notproduce physiological symptoms for years.Hydrogen sulfide (H2S) is a good example of an acutely toxicsubstance which is immediately lethal at relatively lowconcentrations. Exposure to a 1,000 ppm (parts per million)concentration of H2S in air produces rapid paralysis of therespiratory system, cardiac arrest, and death within minutes.Carbon monoxide (CO) is a good example of a chronically toxicgas. Carbon monoxide bonds to the hemoglobin molecules in redblood cells. Red blood cells contaminated with CO are unable totransport oxygen. Although very high concentrations of carbonmonoxide may be acutely toxic, and lead to immediate respiratoryarrest or death, it is the long term physiological effects due tochronic exposure at lower levels that take the greatest toll ofaffected workers. This is the situation with regards to smokers,parking garage attendants, or others chronically exposed to carbonmonoxide in the workplace. Exposure levels are too low to produceimmediate symptoms, but small repeated doses reduce the oxygencarrying capacity of the blood over time to dangerously low levels.This partial impairment of the blood supply may lead over time toserious physiological consequences.Because prudent monitoring programs must take both time framesinto account, there are two independent exposure measurementsand alarm types built into the MultiPro design.

1. Warning and Danger AlarmsOSHA has assigned some, but not all, toxic substances with aceiling level which represents the highest concentration of a toxicsubstance to which an unprotected worker should ever beexposed, even for a very short time. The default Warning andDanger alarm levels in the MultiPro are less than or equal to theOSHA-assigned ceiling levels for both CO and H2S. Never enteran environment even momentarily when concentrations oftoxic substances exceed the level of either the Warning or theDanger Alarm.

Time History Graph

Ceiling

2. Time Weighted Average (TWA):The maximum average concentration to which an unprotectedworker may be exposed over an eight hour working day is calledthe Time Weighted Average or TWA value. TWA values arecalculated by taking the sum of exposure to a particular toxic gasin the current operating session in terms of parts-per-million-hoursand dividing by an eight-hour period.

Time History Graph

Ceiling

TWA (8 hour)

3. Short Term Exposure Limits (STEL):Toxic substances may have short term exposure limits which arehigher than the eight hour TWA. The STEL is the maximumaverage concentration to which an unprotected worker may beexposed in any fifteen minute interval during the day. During thistime, neither the eight hour TWA or the ceiling concentration maybe exceeded.Any fifteen minute periods in which the average STELconcentration exceeds the permissible eight hour TWA must beseparated from each other by at least one hour. A maximum offour of these periods are allowed per eight hour shift.

Appendix B CalibrationFrequencyRecommendationOne of the most common questionsthat we are asked at Biosystems is:“How often should I calibrate my gasdetector?”

Sensor Reliability andAccuracyToday’s sensors are designed toprovide years of reliable service. Infact, many sensors are designed sothat with normal use they will onlylose 5% of their sensitivity per yearor 10% over a two-year period.Given this, it should be possible touse a sensor for up to two full yearswithout any significant loss ofsensitivity.A lot of sensors indeed do last thatlong with only minimal loss ofsensitivity. However, there are anumber of reasons why a sensormay unexpectedly lose additionalsensitivity or even fail to respond togas. Such reasons includedesiccation, poisoning, physicalrestriction of airflow, overexposure,leakage, and mechanical damagedue to dropping or immersion.

Verification of AccuracyWith so many reasons why a sensorcan lose sensitivity and given thefact that dependable sensors can bekey to survival in a hazardousenvironment, frequent verification ofsensor performance is paramount.There is only one sure way to verifythat a sensor can respond to the gasfor which it is designed. That is toexpose it to a known concentrationof target gas and compare thereading with the concentration of thegas. This is referred to as a “bump”test. This test is very simple andtakes only a few seconds toaccomplish. The safest course ofaction is to do a “bump” testprior to each day’s use. It is notnecessary to make a calibrationadjustment unless readings are offby more than 10% of the expectedvalue.

Lengthening the Intervalsbetween Verification ofAccuracyWe are often asked whether there areany circumstances in which the periodbetween accuracy checks may belengthened.Biosystems is not the onlymanufacturer to be asked this question!One of the professional organizations towhich Biosystems belongs is theIndustrial Safety Equipment Association(ISEA). The “Instrument Products”group of this organization has beenvery active in developing a protocol toclarify the minimum conditions underwhich the interval between accuracychecks may be lengthened.A number of leading gas detectionequipment manufacturers haveparticipated in the development of theISEA guidelines concerning calibrationfrequency. Biosystems proceduresclosely follow these guidelines.If your operating procedures do notpermit daily checking of the sensors,Biosystems recommends the followingprocedure to establish a safe andprudent accuracy check schedule foryour Biosystems instruments:1. During a period of initial use of at

least 10 days in the intendedatmosphere, check the sensorresponse daily to be sure there isnothing in the atmosphere, which ispoisoning the sensor(s). The periodof initial use must be of sufficientduration to ensure that the sensorsare exposed to all conditions thatmight have an adverse effect on thesensors.

2. If these tests demonstrate that it isnot necessary to make adjustments,the time between checks may belengthened. The interval betweenaccuracy checks should not exceed30 days.

3. When the interval has beenextended the toxic and combustiblegas sensors should be replaced uponwarranty expiration. This willminimize the risk of failure during theinterval between sensor checks.

4. The history of the instrumentresponse between verificationsshould be kept. Any conditions,incidents, experiences, or exposure tocontaminants that might have an

adverse effect on the calibrationstate of the sensors should triggerimmediate re-verification ofaccuracy before further use.

5. Any changes in the environmentin which the instrument is beingused, or changes in the work beingperformed, should trigger aresumption of daily checking.

6. If there is any doubt at any timeas to the accuracy of the sensors,verify the accuracy of the sensors byexposing them to knownconcentration test gas before furtheruse.

Gas detectors used for the detection ofoxygen deficiencies, flammable gasesand vapors, or toxic contaminantsmust be maintained and operatedproperly to do the job they weredesigned to do. Always follow theguidelines provided by themanufacturer for any gas detectionequipment you use!If there is any doubt regarding yourgas detector's accuracy, do anaccuracy check! All it takes is a fewmoments to verify whether or not yourinstruments are safe to use.

One Button Auto CalibrationWhile it is only necessary to do a“bump” test to ensure that the sensorsare working properly, all currentBiosystems gas detectors offer a one-button auto calibration feature. Thisfeature allows you to calibrate aBiosystems gas detector in about thesame time that it takes to complete a“bump” test. The use of automaticbump test and calibration stations canfurther simplify the tasks, whileautomatically maintaining records

Don't take a chancewith your life.

Verify accuracy frequently!Please read also Biosystems’ applica-tion note: AN20010808 “Use of‘equivalent’ calibration gas mixtures”.This application note providesprocedures to ensure safe calibration ofLEL sensors that are subject to siliconepoisoning.Biosystems website is located at:
