11–84 EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL
CALIBRATION REQUIREMENTS CHAPTER 11: PROGRAMMING GROUP 2 - METER CALIBRATION
11.1 Calibration Requirements
Calibration on the EPM 5300P requires precise inputs of 120 Volts, 5 Amps, and 2.5 Amps.
The EPM 5300P -G model requires precise inputs of 300 Volts, 5 Amps, and 2.5 Amps. If this
equipment is unavailable, contact us for assistance.
Note
The voltage and current scales are calibrated with the maximum range value 2000 for
current, 14.40 for voltage, 300 for option G. The calibration value can be identical to the
full scale value in GROUP 1, for better accuracy than the specification. However, if a full
scale is ever changed to a higher value than the calibrated value, the value may be less
accurate.
