It’s mainly used to measure and display the parameters of electric circuit in a high-accuracy manner, such as voltage, current, active power, reactive power, apparent power, power factor, frequency, four-quadrant electric energy, harmonic, content (2^nd~31^st) of voltage and current, total harmonic content of voltage and current, degrees of voltage and current unbalance (including positive sequence, negative sequence and zero sequence), etc.

The meter supports functions like switch input, switch output, analog quantity output, RS485 interface and so on.
