CAUTION:
When reading the meter display, all consumption and demand values must be multiplied by
the correct multiplier to calculate true value. This includes all register values (kWh, kW,
kVARHLg, kVARHLd, etc.) and Phase Diagnostic values (real time Amps, Watts, etc.).
Volts, phase angle, frequency and power factor are displayed on the LCD as their true values
and should not be multiplied.
The multiplier value is dependent upon the ratio of the external Current Transformers (CTs)
and can be different for different meter points. The following table MUST be used to obtain
actual consumption and demand readings.
