Magtrol Model 5300 Three Phase Power Analyzer

Chapter 9 - Calibration

NOTE: Calibration on the 25 and 100

Amps ranges may have to be

done at less than full range scale,

depending on your calibration

equipment.

VOLTS BALANCE

1. Go to the 5300 PA 150 VOLTS range.

2. Set the voltage calibrator for + 150 volts DC output.

Note the VOLTS display reading.

3. Reverse the calibrator polarity to -150 volts DC. If

the plus to minus display readings differ by more

than ± 2 LSD, connect a digital voltmeter at

amplifier 78B147-U4 pin 14 and adjust trim pot

78B147-R10 for zero ± 0.1 millivolt dc.

CURRENT BALANCE

1. Go to the 5300 PA 5 amp. range

2. Set the current calibrator for + 5 Amps DC output.

3. Note the AMPERES display reading. Reverse the

calibrator polarity to - 5 Amps DC. If the plus and

minus display readings differ by more than ± 2 LSD,

connect digital voltmeter at amplifier 78B147-U1

pin 14 and adjust trim-pot 78B147-R2 for zero ±

0.1 millivolt DC.

WATTS SCALE FACTOR

1. Set the volts and current calibrators for 150 VDC

and 5 Amp DC output.

2. Adjust trim pot 78B147-R18 for 750.00 WATTS

display reading.

3. Confirm AC measurement accuracy by setting the

calibrators for 150 VRMS and 5 Amps RMS at 60

Hz. The WATTS display should read close to

750.00 watts and be within the specification

accuracy. See Section 2 - Specifications.

NOTE: Adjust current calibrator's phase

shift control for zero phase angle

between volts and amps (peak the

watts indication) - see

"Calibration Verification--AC,"
