The unit on the display depends on the secondary rated power, VT ratio, and CT ratio. It is fixed, and cannot be changed.
Ex. For active power, the measuring range and unit are determined as follows.
Secondary rated power is the rated power in the table below.
For voltage ranges of 150 V, 300 V, 600 V, the rated input voltages are 110 V, 220 V, and 440 V. For single phase 3 wire configurations, the rated voltage for a voltage range of 300 V (fixed) is 200 V. For three-phase four-wire, select voltage range for the phase voltage.
