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.
