Performance Features:
1. It can measure resistive current either by direct testing method or by harmonic method indirectly.
2. Three-phase voltage and three-phase current are collected and displayed simultaneously, achieving true three-phase simultaneous measurement.
3. The reference voltage signal can use 3PT, 1PT, no PT, wireless, induction, and other methods.
4. The instrument is equipped with a rechargeable battery, calendar clock, and micro printer, and can store 500 sets of measurement data.
5. To facilitate the analysis of resistive current, side-phase compensation can be either prohibited or allowed.
6. To save printing paper, waveform printing can be disabled.
