UNPACKING
The Model 5100 is packed in reusable, shock resistantpacking material that will protect the instrument duringnormal handling. In the event of shipping damage,immediately notify the carrier and MAGTROLCustomer Service Dept.
Save all shipping materials for reuse when returningthe instrument for calibration or servicing.
POWER
The 5100 PA is factory wired for either 120 or 240Vrms, 50/60 Hz, power at 40 volt amps, max. The linecord is a detachable NEMA standard 3 wire which plugsinto the rear access power entry and filter module of the5100 PA. The line cord must be detached from the PAduring servicing.
NOTE: The standard 5100 is factorywired for 120 Vrms power.Wiring for 240 Vrms is availableon special order.
FUSE REPLACEMENT
Remove the line cord and carefully pry up and removethe fuse holder. Use a 1/2 Amp slow blow fuse for 120Vrms or a 1/4 Amp slow blow fuse for 240 Vrms power.
SAFETY
SECURELY GROUND the 5100 PA case byconnecting a good earth ground at the ground stud thatis located on the rear panel. Use a number 12 AWG, orlarger wire.
CONNECTORS
Plugs that mate with 5100 PA connectors:
Superior Electric Supercon®
INPUT (plug, white, female) - PS50GWT
OUTPUT (plug, white, male) - PP50GWT
VOLTS HIGH (plug, black, female) - PS25GB
VOLTS LOW (plug, white, female) - PS25GWT
For your convenience, the above connectors are suppliedwith your 5100 PA.
Use only the above connectors.
NOTE: GPIB (IEEE-488) - 24 Pin busstandard. Not included, must beordered separately.
MAXIMUM RATINGS
LOAD voltage: line to line, or line to common is 600Vrms.
LOAD current: 50 Amperes rms, continuous.100 Amperes rms, 30 sec. max.
REMOTE VOLTAGE SENSE: Line to line is 600Vrms. Also, do not exceed 600 Vrms differentialbetween the VOLTS INPUT and AMPS OUTPUTterminals.

Magtrol Model 5100 Single Phase Power AnalyzerChapter 1 - Introduction
INSTALLATION
ORIENTATION
The 5100 PA must be mounted within ± 20 degreesfrom horizontal. This insures proper operation of themercury shunt bypass relay.
ELECTRICAL LOAD
Use wire rated for the maximum load current and voltageexpected.
Hint - use wire gauge large enough to insure goodconnector set screw compression on the wire leads.Soldering may be used instead of, or in addition to theset screw.
IEEE-488 (GPIB)
Use only high quality shielded cable conforming to thebus standards.
INITIAL CHECKOUT
Make sure the circuit is completely de-energized byremoving all voltage sources.
Plug the 5100 PA into the 50/60 Hz power mains.Switch the POWER rocker switch (red) to ON andobserve that the digit readouts flash on-off-on and thenindicate zero or a small number. The VOLTS andAMPERES range switch indicator lights will allilluminate. The voltage ranges sequence down from 600through 15 and current ranges sequence down from 50through 2. The 15 Volt, 2 Amp and AUTO indicatorswill remain illuminated. The MODE indicators do notlight during this power-on sequencing.
Your 5100 PA has passed the initial check.
TRANSIENT OVERLOADS
Connect an appropriate transient suppressor in parallelwith all inductive loads. Consult the suppressor vendorsapplication literature for proper selection and sizing.
Damage to the 5100 can result fromexcessive voltage transients generatedby unsuppressed inductive loads.
This damage is not within the scope ofthe normal instrument service and is notcovered by the MAGTROL WARRANTY.
CURRENT OVERLOAD
NO FUSES are in the 5100 PA measuring circuits.Therefore, excessive current passed through the AMPSterminals will cause excessive internal heating andpossible unit damage.
This overload abuse is not covered bythe MAGTROL WARRANTY.
Know your load conditions and double check allconnections. If an overload should occur, immediatelyremove all power , locate and correct the problem beforere-energizing your circuit. If a circuit breaker isinstalled, it must be installed on the LOAD side of the5100 (downstream). This will keep the low impedanceof the input line connected to the 5100 PA for surgesuppression. If the line side must also contain a breaker,it should be delayed in operation to open after the loadside breaker has opened.

THREE PHASE, 3 WIRE DELTA CONNECTIONS
Load true power is the algebraic sum of the two wattmeter readings ( W = W1 × W2 ) regardless of load powerfactor or balance. The general discussion from Figure 2 applies.
NOTE: For load power factor = 0.5, one wattmeter reads zero, as the power factor goes less than 0.5it's power is negative and is subtracted in the algebraic watts summation. The 5100 PA willnot display a minus sign for this condition. If your 5100 has the Analog Output Option, thewatts (relative) polarity is available by measuring both analog watts outputs. For powerfactors greater than 0.5, the polarity of both wattmeters will be the same therefore, true powerin watts is simply the unsigned sum of the wattmeter readings.
SINGLE PHASE AC OR DC CONNECTIONS
This circuit utilizes the 5100 PA REMOTE VOLTAGE SENSE feature by measuring the voltage at the load. Thisincreases measurement accuracy by eliminating line voltage drop from the power measurement. For safety, anoverload circuit breaker (CB) removes all load voltage during an over current condition. Make sure that connectionsfrom the remote voltage sense lines are connected very close to the circuit breaker and the lines from the breaker toload are as short as possible.
If a circuit breaker is used in the input line to the 5100 PA, a circuit should be used that preventsthe breaker from opening until after the load side breaker has operated. Otherwise, potentiallydamaging inductive transients will be applied to the 5100 PA. Damage caused by thesetransients are outside the scope of the MAGTROL WARRANTY.
For voltage sense lines less than 25 feet in length, a twisted pair of #20 gauge (or larger) wire can be used. For lineslonger than 25 feet or lines grouped with other AC conductors, shielded cable should be used. Connect the shield atthe 5100 PA GND terminal. If the wires connecting the load to the 5100 PA OUTPUT are short and the resultingvoltage drop is insignificant, the voltage sense connections can be made at the rear panel of the 5100 PA.
Connect the chassis ground terminal to a good earth ground. Use at least #12 gaugeinsulated copper wire.

GENERAL
Using Sections 1 and 3 as a guide, connect the 5100.Before connecting the power mains, double check allconnections using an Ohmmeter.
Verify that the overcurrent circuit breaker is open andconnect the power mains.
Observing the 5100 front panel indicators. Turn the 5100power switch ON and confirm proper operation - referto “Initial Checkout” under Chapter 1 - Introduction.
Energize the power mains and apply power to the loadby closing circuit breaker CB. If improper operationoccurs, immediately disconnect power mains, locate andcorrect the problem.
The 5100 has three MODES - HOLD; PF (power factor)and AVG (averaging); five AMPS ranges plus AUTO(autoranging); and five VOLTS ranges plus AUTO. Allhave adjacent red LED's indicating the active mode andmeasurement range.
AMPERES DISPLAY
The AMPS display is a four digit, floating point displayof true AC rms or DC current flowing into the AMPSINPUT connector (white) on the rear panel. For detailedspecifications refer to Chapter 2 - Specifications.
The 5100 defaults to AUTO (auto ranging) at turn on.AUTO up-ranging occurs if the rms current exceedsthe top of the range value plus about 5% or, if a peakvalue exceeds full range rms value × 1.414 plusapproximately 5%.
AUTO down ranging occurs when the current is justless than full range value of the next lower range.
Selection of any amps range pushbutton activates theselected range by overriding the AUTO- range selection- AUTO LED goes off and selected AMPS LEDilluminates. However, the AUTO up-range function isalways silently monitoring the current and is ready toup-range the instrument if the current increases abovethe range full scale. If the current falls below the valueof the originally selected range, that range will then re-activate. The instrument will automatically up-range
from the measured current but will down-range only tothe selected range. The display will show "HELP" whenthe 5100 PA maximum current is exceeded.
VOLTAGE DISPLAY
The VOLTS display is a four digit, unsigned floatingpoint display of AC rms or DC voltage between therear panel HIGH (black) and LOW (white) terminals.
The voltage input is differential (neither terminal tiedto common) allowing connection at a remotely locatedload. This remote connection removes the voltage dropin the load connection wires from the powermeasurement. The VOLTS - LOW terminal (WHITE)must be connected to the AMPS - OUTPUT line at theload - see Figure 1.
The AUTO and manual VOLTS range selection isidentical in operation to the AMPS as described above.
WATTS OR POWER FACTOR
The WATTS display is five digit, unsigned floatingpoint display of power in WATTS or POWER FACTORas a decimal number.
WATTS is the power ON default MODE, press theMODE - PF button for POWER FACTOR MODE.Watts measurements are from milliwatts through 30kilowatts, and Power Factors from 0.0001 through0.9999.
WATTS = V × I × cos θ = TRUE POWER
The WATTS range is set by the AMPS and VOLTSactive ranges.

MODE HOLD
The HOLD pushbutton may be depressed at any time.When depressed, all internal machine functions arehalted except auto ranging. If the AVG (averaging)function is active when the HOLD button is depressed,the last running average value of AMPS, VOLTS andWATTS will be latched on the display.
10
Magtrol Model 5100 Single Phase Power AnalyzerChapter 4 - Operation
The HOLD and AVG functions can be combined. Seethe MODE AVG paragraph, below.
MODE AVG
AVG is an integration or averaging function on VOLTS, AMPS and WATTS.
Averaging remains active across manual or auto rangechanges.
The averaging function is useful in stabilizing the displaywhen digits are changing because of slowly varyingvalues. Integration periods from seconds to minutes maybe needed.
The HOLD and AVG functions work together. Whenentering AVG with HOLD off, the averaging registersare cleared and integration starts from the current value.With the HOLD function active first, pressing AVGstarts the integration point from the last stored valuesof AMPS, VOLTS or WATTS. When AVG is turnedoff, non-averaged values are displayed and the valuesat that instant are stored in non-volatile RAM and uponreentering the AVG mode will be returned as the newaveraging starting points. Also, when the Analyzerpower is turned off, the last averaged values stored willbe held and returned when the AVG function isreactivated.
The HOLD - AVG function permits truly integratedpower measurements where power is appliedintermittently or, where a combination of devices requireintegrated measurements with interruptions betweenmeasurements.
NOTE: WATTHOURS can bedetermined by using the AVGfunction and a timing clock.
Watthours = (watts avg × time inhours)
Power Factor (PF) is notaveraged.
ANALOG OUTPUT OPTION
This option provides analog output signals for AMPS,VOLTS and WATTS. These three analog outputs withtheir common are isolated from the measured circuitsby 750 Volts continuous and 2500 Volts test breakdown.
The outputs are provided through a standard 5 pin DINstyle connector that is located on the rear panel of the5100 - see figure 9 for connections.
The analog output voltage is calibrated to 5.00 VoltsDC for full scale input on the 10 Amp current rangeand the 150 Volt voltage range (1500 Watt range). Theactual output on other ranges will be a relative valueclose to 5 Volts due to tolerances in gain resistors andinstrumentation amplifiers. For example: Full scaleoutput on the 15 Volt range may be 4.95 Volts DC.The analog output at 12 Volts input would be FS / Rng× Rdg or 4.95 / 15 × 12 = 3.96 Volts DC.
NOTE: Analog output of POWERFACTOR is not provided

GPIB (IEEE-488)
The IEEE-488 or GPIB (General Purpose Interface Bus)provides direct connection and control of the 5100 fromany appropriately equipped computer for the purposeof data acquisition and display. MAGTROL factoryassistance is available.
HARDWARE INSTALLATION
A GPIB interface requires installation of an interfacecard in the host computer and driver software residenton the PC's hard disk. MAGTROL can supply theNational Instruments Corp. GPIB-PC2A® interface, forIBM® or compatible PC's.
SOFTWARE INSTALLATION
Formatting and initialization assistance is available fromMAGTROL Customer Service.
All GPIB data acquisition systems require the use oftermination characters to signal the conclusion of a dataexchange. The 5100 uses the Hewlett Packard - HPIB™standard ASCII termination characters "Carriage Return(CR) and Line Feed (LF)", in that order. On a writecycle, the 5100 looks for the CR-LF to signal completionof an instruction and transmits these characters uponconclusion of a data read cycle.
PRIMARY ADDRESS
All instruments serviced on the bus have a separateprimary address code. The factory setting for the 5100is twelve (12). This code can be changed by changingthe DIP switch settings that are located on the rear paneland above the GPIB connector. Change this addressonly if there is an addressing conflict with otherinstrumentation on the bus. Refer to the table in Figure10 to set the DIP switch pattern.

IBM® AND COMPATIBLESINSTRUCTIONS
The 5100 PA is configured for the Hewlett Packardstandard termination characters of CARRIAGERETURN (CR hex OD) and LINE FEED (LF hex OA).On a read cycle (5100 to PC), the 5100 expects thestandard IEEE-488 read protocols and primary address.It responds with a data string followed by a CR and LF.This signals the end of a transmission. Upon receipt ofthese characters, the PC must be configured to terminateGPIB communications and proceed with its ownprogram execution. On a write cycle (PC to 5100), the5100 expects to receive: (1) the PRIMARY ADDRESS;(2) INSTRUCTIONAL DATA STRING (3); theTERMINATION CHARACTERS of CR and LF. If
12
Magtrol Model 5100 Single Phase Power AnalyzerChapter 5 - GPIB Communication
these characters are not forthcoming, the 5100 has noway of knowing when to terminate handshaking, resetthe GPIB and continue with its program loop. If omitted,the only way to restore operation is to cycle power OFF-ON or, force a GPIB interface reset - if available.
READ CYCLE
In read (5100 to PC) command mode, the 5100 willoutput a data string containing the information on theAMPS, VOLTS and WATTS display.
The ASCII output format is:
A= aa.aaV=vvv.vW=ww.www<CR><LF>
aa.aa is the CURRENT value as displayed on the AMPSdisplay.
vvv.v is the VOLTAGE value as displayed on theVOLTS display.
ww.www is the WATTS value as displayed on theWATTS display.
The string length is always 24 characters. Most PC'swill require that the input string length be dimensioned.
If the 5100 is in PF (power factor) MODE instead ofWATTS, the "W" changes to "P".

AMPERES TRANSDUCING
Current measuring is accomplished using two calibratedmanganin meter shunts. For the 2 ,5, 10 and 20 Ampranges, 0.011 Ohms resistance from two seriesconnected metering shunts provide a voltage to adifferential input calibration amplifier. In the 50 Amprange, the low current section of the shunt is bypassedby a low resistance mercury relay leaving 0.001 Ohmof active shunt. See Figure 10.
This autorange activated shunt bypass relay protects themetering shunts from overheating for overloads up to100 amps for about 30 seconds.
VOLTAGE SENSING
The VOLTS input terminal connects a 1.5 megohmresistive voltage divider to a differential input amplifierto provide scaled voltage for measurements.

ANALOG PROCESSING
Input signals proportional to AMPS and VOLTS areamplified and scaled for each range. These scaledsignals pass through a true rms to DC converter, avoltage to frequency converter and an optical isolationcoupler. The resulting signals represent true rms currentand voltage as a function of frequency (AF0 and VF0,respectively).
Also, scaled AMPS and VOLTS signals are input to aprecision four quadrant X-Y multiplier, averaged bypassing through an active two pole Butterworth filter,converted to frequency in a voltage to frequencyconverter and isolated through an optical coupler. Theresulting signal, WF0, represents true power - (V × I ×Cos θ) in WATTS as a function of frequency.
There is 2500 volts isolation between the measuredcircuit and the AF0, VF0 and WF0 frequency signals.
See Figure 12 for a block diagram.

DIGITAL PROCESSING
Frequency proportional signals of AMPS, VOLTS andWATTS (AF0, VF0 and WF0, respectively) areintegrated for a precise period of 0.1 seconds for digitalconversion and processing via an eight bitmicrocomputer. The MPU controls functions of rangecontrol, auto-zero, calibration, BCD conversion,parameter display and GPIB transmission.
The MPU acquisition and conversion rate is 100milliseconds (10 readings per second) and the displayupdates at 500 milliseconds (2 updates per second).The MPU scans all front panel pushbutton control inputs25 times per second. When a pushbutton is depressed,the appropriate program loop is entered and the functionis executed on the next program cycle. No damagewill result to the 5100 PA from any combination ofpushbutton selections.
In the AVG MODE (averaging), the 5100 PA integratesthe 10 data readings per second (AMPS, VOLTS andWATTS) and then samples the averaged value fordisplay. As the sampled readings accumulate, thechanging display digits will steady down to provide astable measurement of true power (computed fromaverage VOLTS and AMPS). This technique workswell when the displayed digits are changing too fast tobe recognized resulting from changing powerconsumption.

GENERAL
Complete calibration of the 5100 PA is beyond thecapabilities of most users. MAGTROL Inc.recommends that the 5100 PA should be returned tothe factory for calibration certifying the instrument tofull specifications.
NOTE: breaking the factory CAL VOIDsticker voids the MAGTROLWARRANTY - Please call theMAGTROL Service Departmentbefore you break this seal.
However, this section includes CALIBRATIONACCURACY VERIFICATION procedures and stepsto make minor trim-ups of calibration.
NOTE: Performing these steps VOIDSthe factory CALIBRATIONCERTIFICATION that comeswith the 5100 PA., the factoryseal will be broken.
TEST SETUP
The recommended test setup is shown by Figure 13.
The accuracy of the voltage and currentstandards used for calibration shouldbe at least four times the accuracy ofthe 5100 PA specifications. Theequipment shown in this test setupmeets this requirement.
To accurately measure AC power it isimportant that the current source havea phase shifting control. With such aphase adjustment, phase shift causedby incidental circuit inductances canbe compensated for by adjusting thephase of the current wave form to beexactly in phase (zero phase shift) withthe voltage wave form.
Sources of incidental circuit inductance include thecurrent shunts within the 5100, output impedance ofthe calibrators, impedance of the load and wiringinductance.
Since the current calibrator output is usually a lowimpedance with low compliance voltage, the 5100'scurrent measuring shunts are the circuits majorresistance. Let's take a representative example andcompute the resulting phase shift:
Let L = 10 µhenries (total of shunt, wiring, etc.)Let RSHUNT = 0.011 Ohm; RWIRING = 0.01 OhmR = 0.011 + 0.01 = 0.021 OhmsLet F = 60 Hz ∴ 2π F L ≈ 0.004θ = Arctan (2π FL / R) = Arctan (0.004 / 0.021)θ ≈ 11 degrees, or about 1.8 % measurement error.
This error can be eliminated by adjusting the calibratorsvariable phase shift control. This demonstrates the needfor care in making power analyzer calibrationmeasurements.

CALIBRATION VERIFICATION
Refer to Figure 13, for the recommended test setup.
If other test equipment is used, appropriately modifythe test steps for your equipment.
Potentially lethal voltages are used inthe following test steps.- avoidelectrical shock. Refer to yourcalibrator operator manual foroperating instructions - thesecalibrators generate lethal voltages,extreme care is necessary.
The three steps of the calibration verification are asfollows:
1. Volts Calibration Check
2. Amperes Calibration Check
3. Watts Calibration
Set both the VOLTS and AMPERES calibrators tostandby mode.
VOLTS CALIBRATION CHECK
DC:
1. On the 5100 PA, depress the 15 volts rangepushbutton.
2. Set the volts calibrator for zero volts DC and operatemode.
The 5100 VOLTS display should read zero +0.0001% max of volts full scale range.
3. Set volts calibrator for + 15 volts DC.
The 5100 VOLTS display should read 15.00 volts.
4. Record the VOLTS readings.
5. Set the calibrator for -15 volts DC and repeat theabove step.
6. Record the VOLTS readings.
7. Repeat the above 6 steps for the 30, 150, 300 and600 volts ranges.
Lethal Voltages are Used!
8. Compare the above readings to the 5100 PAACCURACY SPECIFICATIONS in Chapter 2 ofthis manual.
The (+) and (-) readings should be within ± 2 leastsignificant digit (LSD) of each other.
AC:
1. Set the volts calibrator for 60 Hz and repeat thevolts checks as outlined in the DC test above.
NOTE: If a beat frequency effect isexperienced between thecalibrator output and the 60 Hzpower line frequency, try settingthe calibrator for 80 Hz instead of60 Hz.
2. Set the volts calibrator to standby mode.
AMPERES CALIBRATION CHECK
DC:
1. On the 5100, depress the 2 AMPERES rangepushbutton.
2. Set the current calibrator for zero amperes andoperate mode.
The AMPERES display should read zero + 0.0001%max of range full scale.
3. Set the current calibrator for + 2 Amperes DC.
The AMPERES display should read 2.000 Amps.
4. Record the current readings.
5. Set the current calibrator for -2 Amperes.
The AMPERES display should read 2.000.
6. Repeat the above 5 steps for the 5, 10, 20 and 50Amp ranges.
7. Compare the above readings to the 5100 PAACCURACY SPECIFICATIONS in Chapter 2 ofthis manual.
18
Magtrol Model 5100 Single Phase Power AnalyzerChapter 7 - Calibration
The (+) and (-) readings should be within ± 2 LSDof each other.
AC:
1. Set the current calibrator for 60 Hz and repeat thecurrent checks outlined above.
NOTE: If a beat frequency effect isexperienced between thecalibrator output and the 60 Hzpower line frequency, try settingthe calibrator for 80 Hz instead of60 Hz.
2. Set the current calibrator to standby mode.
WATTS CALIBRATION CHECK
This step calls for the simultaneous application ofvoltage and current to the 5100 PA.
DC:
1. On the 5100, select a VOLTS and AMPERESrange.
2. Set the volts and current calibrators for a voltageand current near the center of each selected range.
3. Switch the CALIBRATORS to operate mode.
The WATTS readout should show a power that isthe product of the VOLTS and AMPS indications( POWER = V × I ).
4. Compare the 5100 PA WATTS readout to theproduct of VOLTS and AMPS from theCALIBRATORS output. This difference is theWATTS error.
AC:
POWER = V × I × Cos θwhere θ = phase angle between volts and amps.
NOTE: maximum true power is deliveredonly when θ = zero degrees (cosθ = 1). Therefore, the voltscalibrator variable phaseadjustment is set for zero phasebetween the volts and amps at theinput to the 5100 PA. Refer tothe calibrator instruction manualsfor this adjustment procedure.
1. The phase shift control should be carefully set toprovide a peak 5100 PA WATTS indication, thiscorresponds to zero volts to amps phase angle.
2. Repeat the procedure as used for the DC powerverification and record readings.
3. Compare the recorded reading to the 5100 PA.ACCURACY SPECIFICATIONS in Chapter 2 ofthis manual.
