PROGRAMMING GROUP 2—METER CALIBRATION

WARNING—READ THIS SECTION CAREFULLY BEFORE PROCEEDING:

Any rescaling, such as a change in a transformer ratio, can be accomplished in GROUP 1. Calibration is not necessary.

Meter calibration cannot be performed if the meter is installed for service. The sensing inputs must be connected to a power supply with variable voltage and separate current outputs.

The calibration procedure requires highly accurate and stable input signals. Incorrect readings result from improper calibration procedures. If unsure, return unit to the factory for calibration.

BEFORE calibrating any channel, make a note of its Full Scale Setting (see Chapter 10). Set the Full Scale in accordance with Table 10-2 for calibration. Restore original Full Scale Setting when calibration is completed.

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,

14.40for 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.
