Ic: The dc current output. In case of single phase or two-phase measurement, Ia
and Ib are current output.
②
Ua Ub Uc Uo: The input of measuring voltage. In case of single-phase measurement,
Ua and Ub are voltage input. In case of two-phase measurement, Ua and Ub are the voltage
input of the first channel; Uc and Uo are the input of the second channel.
