General Precautions

General Precautions

Version 2.0 VITRO

We recommend that the key operator perform all periodic maintenance procedures.

Moving Parts
Wherever there are moving parts, such as the dispense blade, slide supply rotors, and the incubator disk, use caution when correcting malfunctions and when operating the analyzer. When either of the covers of the VITROS 250/350 Chemistry System are raised, interlock switches prevent the movement of any high-speed or high-power modules. Other modules are still operational.
Cleaning Solutions
Do not use any solvents or cleaning solutions on the equipment other than distilled or deionized water. Never use ammonia cleaners on or near the analyzer.
CAUTION: Do not use solvents, alcohol, ammonia, glass cleaners, or cleaning agents containing abrasives to clean the control unit monitor. These items will damage the touch screen and impair your ability to inter-act with the analyzer computer.

CAUTION: Do not use solvents, alcohol, ammonia, glass cleaners, or cleaning agents containing abrasives to clean the incubator evaporation caps. These items will damage the caps and affect system performance.

CAUTION: Do not touch or clean the Spectralon reference material.

WARNING: Dispose of paper towels and cotton swabs used to clean the analyzer following biohazard procedures. These items may be contaminated with serum or other body fluids.

Clean contaminated analyzer components using a 70 percent isopropyl alcohol in water solution when suggested in the following maintenance procedures. Be sure to use no more than a 70 percent concentrated solution. It is critical that enough water is present to hydrolyze and thus break down proteins.

NOTE: Do not contaminate any other fluids (for example, VITROS 250/350 System Reference Fluid) with isopropyl alcohol solution. NO fluids used on the analyzer should be contaminated with isopropyl alcohol solution or erroneous results will occur. Rinse all components thoroughly with warm distilled or deionized water to remove all traces of isopropyl alcohol.

Do not autoclave any component unless autoclaving is specifically indicated to be an acceptable alternative.

NOTE: You may leave the analyzer on, unless specified otherwise; but do not process samples while you perform maintenance procedures.

Moving the Equipment
Only authorized field personnel are permitted to move equipment from one location
to another. If the equipment is moved, it should be checked by authorized personnel. The equipment should also be checked if any unusual vibration has occurred that may affect it (for example, heavy construction nearby or earthquake).

2 Periodic Maintenance

Preparing for Periodic Maintenance

Version 2.0 VITRO

This chapter provides you with information for maintaining the VITROS 250/350 Chemistry System. It is divided into three parts—daily, weekly, and as-required maintenance.


After performing each maintenance procedure, make a record of it on a maintenance log. There are sample logs at the end of this chapter and in the Operator’s Quick Guide. You may copy them for your use, or you may want to establish a customized maintenance log for your own laboratory.

If questions arise on maintenance and diagnostics during daily operation of the analyzer, read the manual carefully. If you still need assistance, contact your Customer Support Representative.

WARNING: Assume that all used equipment is contaminated with potentially infectious biological material. Use the “Universal Precautions” rec-ommended by OSHA (Occupational Safety and Health Administra-tion) Bloodborne Pathogen Standard 29CFR1910.1030 when handling or cleaning equipment. In particular:

•Wear gloves, closed shoes, buttoned lab coats, and safety glasses throughout the cleaning and maintenance process.

•Treat all waste materials used in the cleaning process as contaminated. Follow the site procedures for your laboratory to dispose of these materials.

•Handle all equipment with care. Mechanical parts may have edges, pinch points, and corners that could potentially cause injury.

Refer to the “Important Safeguards and Precautions” at the beginning of this manual for more information. In addition, refer to the NCCLS guidelines for “Protection of Laboratory Workers from Instrument Biohazards” (NCCLS Document M29-A).

Emptying Disposal Boxes


2–4 VITROS 250/350 C

There are three disposal boxes located behind the two front doors of the analyzer. You must empty them daily.

NOTES: Be sure testing is complete and sampling is OFF before you empty the disposal boxes. The analyzer does not prevent removal of the boxes while tests are in process. If the mixing-cup array and tip disposal box is removed while sampling is on or if the slide-disposal box is removed while tests are in process, the disposal box tracks may become contaminated.

The slide disposal box holds approximately 800 slides. High-volume laboratories may need to empty the box more often than once a day.





To empty the disposal boxes:

1. Open the two front doors of the analyzer.

2. Remove the three disposal boxes (the mixing cup array and tip disposal box, the slide disposal box, and the cartridge disposal box) from the analyzer.

3. The mixing cup array and tip disposal box and the slide disposal box contain liners. Discard the two liners and their contents following your established laboratory procedures for the disposal of biohazardous materials.

ssume that all used equipment is contaminated with potentially nfectious biological material. Use the “Universal Precautions” recommended by OSHA (Occupational Safety and Health Administration) Bloodborne Pathogen Standard 29CFR1910.1030 when handling or cleaning equipment. In particular:

• Wear gloves, closed shoes, buttoned lab coats, and safety glasses throughout the cleaning and maintenance process.

• Treat all waste materials used in the cleaning process as contaminated. Follow the site procedures for your laboratory to dispose of these materials.

• Handle all equipment with care. Mechanical parts may have edges, pinch points, and corners that could potentially cause injury.

Cleaning the Analyzer
1. Empty the disposal boxes and any slides, cups, tips, or fluids.
2. Clean all obvious materials from the outside surfaces of the analyzer with a cloth that is moistened with soapy water. Avoid excessive use of water. Rinse with water to remove soap residue.

3. Clean the control unit, monitor screen, and the keypad cover with distilled water.

4. Clean potentially contaminated areas of the analyzer with a 70 percent isopropyl alcohol in water solution.

NOTES: Be sure to use 70 percent alcohol and not more concentrated solutions. It is critical that enough water be present to hydrolyze and thus break down (denature) proteins.

Ten percent bleach is not recommended for general cleaning as it can be corrosive to metal parts.

17. Follow the instructions below to determine when to update correction factors.

If Summary Screen Shows: Update?

• Two asterisks (**) or no asterisks in the New WCF or White Dr S.D. columns (no values with three asterisks)

AND

• New BCF values are all within typical range1

Yes.

Continue with step 18 on the next page.

• Two asterisks (**) or no asterisks in the New WCF or White Dr S.D. columns (no values with three asterisks)

AND

• Any New BCF value is outside of typical range1

No.

Check for errors2 and repeat test.

Call your Customer Support Center if New BCF values are out of range after you repeat the test.

• Any New WCF or White Dr S.D. value with three asterisks (***)

AND

• New BCF values are either within or outside of typical range

Yes—if service was performed or you have a new lot of correction factor slides.3 Continue with step 18 on the next page.

Otherwise, check for errors2 and repeat test.

Call your Customer Support Center if any New WCF or White Dr S.D. values have three asterisks after you repeat the test.

1 It is common for three flashing asterisks to appear in front of New BCF values, regardless of how many times the correction factors test is repeated. Typically, BCF values should fall in the range [-0.0020 to 0.0020].

2 Check for the following errors and repeat the correction factors test.— Ensure that the reference slides were inserted correctly. Reference slides should be

inserted ribbed side down.— Ensure that the assay values from the White or Black Reference Slide cartons were

entered correctly.3 Three asterisks in front of New WCF values usually indicates that something has

changed in the analyzer’s optical system. This can happen if a service procedure has just been performed, such as the installation of a new internal reference or a new lamp. This can also happen if you have a new lot of correction factor slides. If there is a valid reason for a large change in the correction factors (three asterisks), you should update the correction factors.


Diagnostics


3–28 VITRO

18. The prompt line will ask if you want to update the correction factors automatically. If you update the correction factors, repeat the entire correction factors test again from step 1 to verify the new values.

— To update the correction factors automatically, type “Y” for yes and press the Enter key on the keyboard. The update takes about ten seconds.

— To end the test without updating the correction factors, type “N” for no and press the Enter key on the keyboard.

Warning: If you update the correction factors with inappropriate values, patient results may be affected. If this happens, you can manually re-enter previous correction factors from the printouts you made in step 15 using “WCF Manual Entry,” found in the Operator’s Manual.

19. Close the analyzer covers.

20. Touch RETURN to return to the Setup/Adjustments screen, or touch RETURN TO MAIN DIAG MENU to return to the main Diagnostics screen.

Sample Metering

Details on how to run each performance test are found on the following pages.

Sample Metering T
wo sample metering performance tests are available:
• Leak/Hysteresis Test—Performs a sequence of four checks: A/D reference voltage check, transducer check, leak test, and hysteresis test.

— The A/D reference voltage check reads and displays the A/D converter output.

— The transducer check monitors and displays the pressure as voltage values while the sealed tip is subjected to a series of aspirations followed by a series of dispenses.

— The leak test verifies that a closed or sealed system can be created in the sample metering assembly when the proboscis picks up a tip, aspirates, and dispenses a sample.

— The hysteresis test measures the ability of the pump (over its full range) to return to its initial value after a set of dispense/aspirate actions. The pump is the portion of the sample metering assembly that causes the pressure changes. (Hysteresis is a physics term that indicates the ability or inability of a stressed system to return to its original state when the cause of stress is removed.)

The four checks are carried out in the order in which they are listed above. You can end the leak/hysteresis test after completing each check or continue with the next check in the sequence. If you choose to stop the leak/hysteresis test before all four checks have been completed, you must start the test from the beginning to perform the checks missed. For instance, you cannot go directly to the leak test without first doing the A/D reference voltage check and the transducer check.

• Drop Detection Test—Verifies that the sample metering drop detection and the slide recognition sensor are functioning properly. This sensor must tell the analyzer a drop of sample was dispensed on the slide and a slide is actually present in the slide block to accept a sample drop.

ou can use these performance tests to verify or assess the operation of he incubator disk and those mechanisms that control it.

Two incubator performance tests are available:

• Incubator Pad Reflectance—Verifies that there is a consistent level of reflectance from one incubator pad to the next in the incubator. This ensures accurate and precise slide readings for any test located in any incubator nest position.

• Incubator Position Timing—Verifies that the nest-to-nest rotational timing is consistent for all nests on the incubator disk. This also verifies that the aperture in each nest is present and centered over the reflectometer read station at a constant time interval for slide readings to be taken. This ensures accurate and precise slide readings for any test located in any incubator nest position.

Testing Incubator Pad Reflectance N
OTE: The white and black correction factors must be set before this test will run correctly. Refer to the “Rate/CM Correction Factor Test” in the “Setup/Adjust” section earlier in this chapter.

ou can use these performance tests to verify proper operation of the arious mechanisms that make up the reflectometer assembly.

Three reflectometer performance tests are available:

• Shutter Test—Verifies the performance of the shutter and those mechanisms involved with the shutter operation. To get precise and accurate results, the shutter must be in the correct position (open or closed) at a specified time.

• Static Test—Evaluates the reflectometer read precision without moving the incubator disk. Having the rotor remain stationary removes any imprecision resulting from the movement or performance of the disk. The more precise the reading taken by the reflectometer assembly, the greater the precision of the test result.

• Dynamic Test—Evaluates reflectometer precision and accuracy. All the readings are taken just as they would be if running a patient test.

ou can use these performance tests to verify the proper functioning of he Reference Fluid Metering Assembly.

Two reference metering performance tests are available.

• Timing Test—Verifies that the reference fluid metering assembly movements are completed within the time range allowed and within the step range allowed for the reference fluid metering assembly motor. If either the timing or the step range is violated, the ability of the analyzer to deliver a drop of reference fluid to the PM slide properly, to position a drop of reference fluid on the slide properly, or to dispense a drop of reference fluid on the slide accurately will be compromised.

• System Tests—Verifies the proper functioning of the reference fluid metering assembly signal processing system, the transducer, and the pump. The reference fluid metering system is checked for leaks. The system test is composed of four subtests.

— Signal Processing Test – Measures the reference coarse gain for the A/D converter.

NOTE: The remaining three subtests are done with the reference tip sealed, creating a closed system. The pressure can now be increased or decreased within the system.

— Transducer Check Test – Monitors the transducer for the effects of changing pressure.

— Leak Test – Looks for leaks in the system. The pressure within the system is increased and/or decreased. Once the system has stabilized from the pressure change, the pressure within the system should not change until the pump is activated for another pressure change. A change would indicate a leak in the system.

— Hysteresis Test – Monitors the consistency of response to increasing and decreasing pressure changes. The pump is the portion of the reference fluid metering assembly that causes the pressure changes. (Hysteresis is a term that indicates the ability or inability of a stressed system to return to the original state when the cause of stress is removed.)

The four subtests are carried out in this order. You can end the system tests after completing each subtest or continue with the next test in the sequence. Whether the next test is performed depends on the success of the test just completed. If completed results warrant further investigation with the system tests, then you should conduct the next test.

— If you choose to stop the system tests before all four subtests have been completed, the test must be started from the beginning to perform the subtest(s) missed; for instance, you cannot go directly to the leak test without first doing the signal processing test and the transducer check test.

ou can use these performance tests to run all mechanical and lectrical electrometer sequences.

Five electrometer performance tests are available.

• Normal Cycle–Verifies the integrity of the electrometer using normal slide reading operations. Verifies the mechanical and electrical operation.

• Contact Drive Timing–Verifies the proper operation of the motor that moves the contact points and that the motor can move the contact points to their intended destination within the time allowed in the software.

• Auto Checks—Verifies the electrical operation of the electrometer by taking readings while the contact points are up, down, or cycling. Any deviations from normal would indicate that the electrometer was at fault rather than any external mechanism.

— Contacts Up—measurements are taken with the contact points in the up position.

— Contacts Down—measurements are taken with the contacts down against the internal test pad.

— Cycle Contacts—basically the same as a normal cycle except the incubator and PM eject blade are not actuated. This isolates electrometer problems to outside or to internal origin.

• Extended Auto Checks—Verifies the integrity of the electronics of the electrometer to uncover extreme bias or surface currents that may adversely affect the accuracy of any slide readings taken, and to identify the presence of any current leaks due to impedance failures or surface contamination.

• Basic Modes—Allows independent mode control and readings from the electrometer. This test is for Clinical Diagnostics Field Engineer use only.

NOTE: The electrometer is reset after each test is completed. However, the electrometer A/D converter recalibrates only when you exit Diagnostics and return to normal operations, when you power down the analyzer and then power up, or when you perform a full reset.

Datalogger Analysis

Datalogger Analysis T

3–114 VITROS 250/350 C

he datalogger logs significant events that occur on the analyzer into a log file. The datalogger turns on automatically when you start up or reboot the analyzer.

There are a maximum of ten log files available. Each time the datalogger is turned on, data is written into a new file. Entry into that file is terminated when you turn off the datalogger. When log file ten is closed, log file one will be written to (erasing the data currently in that file) the next time you turn on the datalogger.

Depending on the nature of the condition you are investigating, you can search datalogger files by chemistry, incubator position, environmental data, and error codes. This will aid you in determining the possible cause of a system-related or intermittent condition.

NOTE: It is not possible to do a datalogger analysis on a file that is currently open. You must close the file first.

5 Troubleshooting

Self-Diagnostic Features

Error Conditions Ti


he analyzer contains numerous sensors and other devices that monitor nstrument performance. Also, each slide is monitored closely as it progresses through the various stations in the analyzer. When deviations from normal operation are discovered by any of the software modules with the control program, the condition is reported to the “error reporter” software module. The error reporter module sends an error indication to the status console on the monitor or to the printer when the power goes down. An error is defined as any deviation from acceptable performance.

Severity Levels Tm
he definition of “error” includes unusual hardware conditions, omentary communication difficulties in the computer system, out-of-
slide conditions, or a sample outside the analyzer’s spline range. A severity level is assigned to each error condition to convey the severity of the condition and to indicate the analyzer’s response to the error. Severity indicators are displayed on line one of the status console when an error occurs.

The number preceding a severity indicator is the total number of errors that have occurred in that severity level since you last examined the error log. Two question marks (??) instead of a number indicate that the number exceeds 92. A description of the five severity levels follows, from the least severe to the most severe.

Troubleshooting

Severity Levels

5–2 VITROS 250/350 C

TransientTransient severity level indicates error conditions that are temporary system conditions and do not normally affect analyzer operation. Transient errors are not reported on the status console because they do not require corrective action. They are, however, logged in a history file on the fixed disk and can be reviewed through the error log screen.

AttentionAttention severity level indicates error conditions that will eventually affect analyzer operation if left uncorrected. Examples of attention errors are low slide conditions and a printer that is off-line. Attention errors are reported on the status console; however, they are not logged in the history file on the fixed disk because they will progress to a higher severity level if not corrected.

ActionAction severity level indicates error conditions that prevent the execution of some but not all operator requests. As implied by its name, immediate operator intervention is suggested to correct the condition. Examples of action errors are out-of-slide conditions or an unsuccessful calibration. Action errors are reported on the status console with an audible alert consisting of a single, long, low tone.

MalfunctionA malfunction is an error condition that prevents the continued operation of one or more of the analyzer components (sample metering, incubator, tip transport, environmental monitoring). If possible, the processing of the slides currently in the incubator will be completed before the incubator is deactivated by the analyzer software. For example, if the reference arm fails to arrive at the tip-locator to meter a potentiometric slide, no more slides will be dispensed. Yet, those slides already in the incubator could be completed. However, if one of the incubator eject blades is stuck in the incubator disk so that the disk cannot turn, the incubator will be deactivated and no more slides will be processed. This method of selective deactivation minimizes the loss of valid test results while preventing damage to the analyzer components. Malfunction errors are reported on the status console accompanied by an audible alert consisting of a single, long, low tone.



Troubleshooting

Error Log Screen

ShutdownA shutdown is an error condition that is of sufficient severity to warrant reloading the control program or resetting the analyzer. Shutdown errors usually indicate an unusual condition in the control program in random access memory or an extreme condition on the fixed disk.

IMPORTANT: The shutdown severity level is usually an instruction to the operator; the analyzer does not turn itself off.

Only conditions in the analyzer’s electrical system or the line voltage can result in an automatic shutdown. However, the Shutdown indicator will be cleared from the status console only after you reset the analyzer. Shutdown errors are reported on the status console (except in rare instances of automatic shutdowns) and are accompanied by an audible alert consisting of a combination of high and low tones.

Error Log Screen
When a severity level indicator is displayed on the status console, you can view the error by touching the status console. This will cause the error log for the displayed severity level to appear on the unit monitor. If more than one severity level is displayed, touching the status console will display the error log for the highest severity level. The error log screen shows a list of the last eight errors for a given severity level. The most recent error appears at the top of the list and will be backlit by the highlight bar. When a new error is added to the list, the eighth error is erased. Although this error is no longer displayed on the screen, it is still retrievable from the Error History Log contained on the fixed disk (except for Attention errors; they are not recorded on the fixed disk).
If there are no errors displayed on the status console, touching the status console will cause the malfunction error log screen to appear on the monitor. Once on the malfunction log screen, you can access any of the other severity levels by touching the severity level target located at the right margin of the error log screen. This is useful when you need to access the error logs but no errors are displayed on the status console. When trying to resolve an analyzer condition, it may be necessary to move back and forth between the error screens and the operating software screens.

Finally, when viewing an error log screen and a new error is displayed on the status console, DO NOT touch the status console to view the new error. This action will cause a message on line three of the status console and an audible alert, consisting of a single long tone. The message is displayed for only a few seconds and says “Touch RETURN to exit displayed errors.” Touching RETURN will exit you from the error log screen. You can now touch the status console to display the error log screen for this latest error. An alternative is to simply touch the severity level target that corresponds to the new error. This also displays the latest error on the monitor.


Troubleshooting

Error Log Screen

5–4 VITROS 250/350 C

An error log screen is illustrated below, followed by explanations.

Date/TimeThis is the date and time that the error was logged. This information is useful when more than one error has occurred. The error posted first is most often the cause of the condition. Following the help text for the first error code could save time in getting the analyzer back into operation. Date and time are also useful when matching an error code to a result printed on a lab report. You can obtain more information about the flagged result by locating the error code that most closely matches the date and time the lab report was printed. Following the help text for this error can help you get the correct reporting result.

Condition CodeEach error condition is assigned a three-character code. The first letter of the condition code indicates the subsystem that posted the error. For example, G31 indicates an incubator error because G = incubator. There is a label on the underside of the top right analyzer cover. This label depicts the letter designation for each subsystem and its location in the analyzer.

Troubleshooting

Error Log Screen

This error condition code is also linked to the troubleshooting Help screens. Each condition code calls up a unique Help screen. The troubleshooting Help screens used with the line drawing label will assist you in your troubleshooting efforts. (For more information on Help screens and the line drawing label, see “Troubleshooting Help Screens” in this chapter.)

The error condition code is also helpful if you request assistance from your Customer Support Representative to correct an error condition.

Severity LevelThe associated severity level is displayed following the condition code.

Module/Error NumberEach error condition is assigned a unique module/error number. This is often referred to as the module/error pair. These numbers may be required when requesting assistance from your Customer Support Representative to correct an error condition.

Error MessageThe error message is composed of two or three parts separated by asterisks. The first part of the message identifies the module that is the source of the problem or the module that is reporting the problem. The second part of the message identifies the location within the module. (This error message component may be omitted from some messages if location cannot be identified or is not applicable.) The final error message component describes the problem. (Messages for prediction error conditions are preceded by the same two-letter code that is printed on the laboratory report. This code is provided so that you can correlate the error message with the printed report.)

The laboratory may choose to have these error messages displayed on line one of the status console in place of the severity indicators. See “Configuring the Analyzer” in Chapter 10, “Options,” of the Operator’s Manual.

RETURN TargetTouching the RETURN target returns the display to the screen that was on the monitor when you touched the status console. The severity level indicator is cleared from the status console when you enter the associated error log screen for all severity levels except shutdown.

UP/DOWN TargetsYou can use these targets to move the highlight bar to the error message for which you desire more troubleshooting information. The highlight bar always rests on the first error in the list when the error log is first displayed.

INITIALIZE Target

When you touch the INITIALIZE target, the analyzer initializes only the systems that were deactivated due to a malfunction error condition. Initialization is necessary to bring the affected system back to operational status after you have performed the recommended corrective actions. If a sample is being metered when you touch the INITIALIZE target, all slides for the sample are spotted before beginning the initialization process. After it is touched, the target changes from bright inverse video to normal video until the initialization process is completed. This initialization process does not affect slides being processed by systems unaffected by the deactivation.

The INITIALIZE target is not operational if any of the analyzer’s interlocked covers are open. If you attempt to initialize with any interlocks open, an Attention error will be generated. Close the covers of the analyzer before trying to initialize.

NOTE: If you experience a malfunction error condition with the electrometer, touching the INITIALIZE target following corrective action will only initialize the mechanical operational status of the electrometer. The electrometer A/D converter recalibrates only when you exit Diagnostics and return to the normal operation, when you power down the analyzer and then power up, or when you perform a full program load/reset.

Severity Level TargetsThese are the targets located at the right margin of the error log screen. All five of the error severity levels are represented by a target. You can touch any one of these targets to display the error log screen for that severity level. The backlit target identifies the currently displayed error log.

NOTE: A transient error target is included here even though this severity level is not displayed on the status console.

When a number of items are listed, you should perform the first item, then check whether the condition has been corrected. If it has not been corrected, proceed to the next item on the list, and so forth, until you have performed all suggested procedures. The first item listed is generally the most frequent resolution for the error.

NEXT/PREVIOUS SCREEN TargetsThese targets appear at the bottom of the error log screen when there is more troubleshooting text about the condition code than can be displayed on a single screen. Touching the NEXT SCREEN target will advance ahead one screen and display additional causes and solutions. This additional information is for trained service personnel. Touching the PREVIOUS SCREEN target will back up one screen.

The NEXT SCREEN target does not appear on the screen on the last or only page of text. The PREVIOUS SCREEN target does not appear on the screen on the first or only page of text.

RETURN TargetTouching the RETURN target returns the display to the error log screen.

Hardware Troubleshooting

Initializing the Analyzer Wa

hen you touch the INITIALIZE target on the error log screen, the nalyzer initializes only the systems that were deactivated due to an

error condition. Initialization is necessary to bring the affected system back to operational status after the recommended corrective actions have been performed.

If a sample is being metered when you touch the INITIALIZE target, all slides for the sample are spotted before initialization begins. Also, this initialization process does not affect slides being processed in systems unaffected by the deactivation. After you touch the target, the target changes from bright, inverse video to normal video until the initialization process is completed. To initialize all the mechanical parts, the analyzer must be in the ON mode.

The INITIALIZE target is not operational if any of the analyzer’s interlocked covers are open. If you attempt to initialize with any interlocks open, an Attention error will be generated. Close the covers of the analyzer before trying to initialize.

NOTE: If you experience an error condition with the electrometer, touching the INITIALIZE target following corrective action will only initialize the mechanical operational status of the electrometer. The electrometer A/D converter recalibrates only when you exit Diagnostics and return to the normal operation, when you power down the analyzer and then power up, or when you perform a full program load/reset.

2. Type “Y” and press the Enter key on the keyboard when prompted.

3. Wait until you see the message, “The analyzer has been shut down. Reset or power down is required.”

4. Turn off the analyzer’s main power switch (O or OFF). Leave the analyzer turned off for at least two minutes before turning the analyzer back on.

5. Turn on the analyzer’s main power switch (I or ON). Wait for the Main Menu to appear (approximately ten minutes).

6. Verify that the correct date and time are displayed in the upper right corner of the screen. To correct the date and time, see the “Special Services” section of Chapter 10, “Options,” in the Operator’s Manual, or see the Operator’s Quick Guide.

NOTE: Make sure the date and time are correct to prevent discrepancies in storage and retrieval of calibration, slide disposal, and patient data.

7. The analyzer is now ready for normal operation.

1. Verify that the cartridge was inserted into the correct slide supply (yellow top label in slide supply 1, white top label in slide supply 2).

2. Verify that the side bar code label on the cartridge is facing the rear of the analyzer.

3. Check the bar code label for damage. If damaged, try using one of the manual cartridge loading procedures, or try a new cartridge.

4. If the label is not damaged, try reloading the cartridge. With a smooth, continuous motion, push the cartridge into the opening as far as it will go. A beep will sound indicating that the cartridge was accepted for loading into the slide supply.

If the cartridge has entered the slide supply, there may be a cartridge jam at the load door. You must remove any jammed cartridge manually. To clear a slide cartridge jam at one of the load doors:

1. Allow all slide processing to complete if possible.

2 Periodic Maintenance

Preparing for Periodic Maintenance This chapter provides you with information for maintaining the

Vitros 250AT Chemistry System. This information is designed to supplement the procedures found in the “Periodic Maintenance” chapter of the Vitros 250 Chemistry System Maintenance & Diagnostics Guide. You should become familiar with both of these chapters before performing maintenance procedures.


After performing each maintenance procedure, make a record of it on a maintenance log. There are sample logs designed for use with the 250AT System at the end of this chapter. You may copy them for your use, or you may want to establish a customized maintenance log for your own laboratory.

If questions arise on maintenance and diagnostics during daily operation of the analyzer, read the Vitros 250 Chemistry System Maintenance & Diagnostics Guide carefully. Refer to this Supplement for procedures that are specific to the 250AT System. If you still need assistance, contact your Customer Support Representative.

WARNING: Assume that all used equipment is contaminated with potentially infectious biological material. Use the “Univer-sal Precautions” recommended by OSHA (Occupational Safety and Health Administration) Bloodborne Pathogen Standard 29CFR1910.1030 when handling or cleaning equipment. In particular:

•Wear gloves, closed shoes, buttoned lab coats, and safety glasses throughout the cleaning and maintenance process.

•Treat all waste materials used in the cleaning process as contaminated. Follow the site procedures for your laboratory to dispose of these materials.

•Handle all equipment with care. Mechanical parts may have edges, pinch points, and corners that could potentially cause injury.

Refer to the “Important Safeguards and Precautions” at the beginning of the Maintenance & Diagnostics Guide for more information. In addition, refer to the NCCLS guidelines for

Periodic MaintenancePreparing for Periodic Maintenance

2–2 Vitros 250 Chemistry System Maintenance & Diagnostics Guide Supplement for 250AT Systems 2/00

“Protection of Laboratory Workers from Instrument Biohazards” (NCCLS Document M29-A).

To access the Periodic Maintenance screen and begin using the periodic maintenance features, touch PERIODIC MAINTENANCE on the Main Menu.

Instructions on using the daily, weekly, and periodic maintenance features are found in the “Periodic Maintenance” chapter of the Vitros 250 Chemistry System Maintenance & Diagnostics Guide. The procedures documented in that volume also apply to 250AT Systems.
