2. Current Only – Does not modify the AC Voltage calibration constants.
3.3.1 Equipment
If you are doing an AC current calibration you will need the following:
1. An accurate instrument (e.g. ammeter or multimeter set to AC current) to
measure current from the generator. Measure as close to the CTs as
possible.
2. A load source to generate two different currents for the calibration
preferably at 25% and 75% of normal maximum load.
3. Knowledge of the number of phases the GSC400 is measuring (A, B, C).
To determine this look at the AC Voltage connections on the back of the
GSC400.
If you are doing an AC voltage calibration you will need the following:
1. A voltmeter to measure the voltage at the GSC400 terminals.
