Characteristics
It can online and offline test the AC feature such as lightning protector full leakage resistance, resistance current, capacity current, power consumption, harmonic component and waveform curve. It has the side phase correction function, it can effectively remove the phase interference, the isolation mutual inductor is set inside the device to thoroughly isolate the device and site PT, the double insurance ensure the safety of PT; The chargeable cell is set inside so that it can be used conveniently in site; It can save as much as 210 group data; It is convenient for reference, it equips with the RS-232 communication interface, it can transfer data, it is whole Chinese character interface operation, and easy to be used.
