10–74 EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL
GROUP 1, FUNCTION 0 CHAPTER 10: PROGRAMMING GROUP 1 – VOLTAGE, AMP AND WATT SCALE SETTINGS
10.1 Group 1, Function 0
- FULL SCALE VOLTAGE SETTINGS, SCALE & DECIMAL POINT PLACEMENT -
Note
Tables 10-2 and 10-3 contain Full Scale Settings for typical voltages and currents
(PT and CT arrangements).
If PT is connected line to line, the full scale can be 14.40 KV. Full scale is 300 V L-N, not 277,
because the factory calibration is 300 V. Be sure the table is based on a meter regulation of
2000 A/D counts. Thus, for best accuracy, all settings should be placed within that range.
10.1.1 Voltage Full Scale:

Note
Press MAX/MIN/LIMITS at any time to cancel before storing the last digit or switch.
