Test Y0 Y △type transformer, display the resistance without conversion. 2. Data analysis of human nature, you can automatically identify the fault in the middle of the waveform, and make a mark; 3. Waveform display is automatically adjusted according to the sampling data and the resistance to the magnitude of the time; 4. The △ type transformer can display the three-phase synchronization; 5. The test can be carried out with or without winding; 6. There are four terminal connection modes, to provide high precision resistance measurement, and no need to wire compensation.
