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.
To change the Full Scale Settings:
NOTE: Press MAX/MIN/LIMITS at any time to cancel before storing the last digit or switch.
