The instrument gives the conclusion in the table below： result inferior Middle Good Best interference Φ 0～74.99° 75～76.99° 77～79.99° 80～82.99° 83～87.99° ≥88° Note 1: The waveform displayed by the instrument is the collected gear signal, so do not use the waveform amplitude to determine the size of the data. Note 2: No PT measurement, fixed UI angle = 83.5 degrees, easy to calculate resistive current。...
- Page 10 Single-phase measurement: (main wiring and three-phase measurement wiring are the same, the wiring of the test product is the phase of which phase is connected, which is not measured.) The detailed wiring of each phase is as follows: 2.1Phase A measurement, the current and voltage lines on the green, red wire clip on the wire hanging, only the corresponding phase A yellow clip.
