1、 Main features of transformer DC resistance tester

1. The instrument adopts two power supply modes: ① mains power~220V power supply; ② The internal lithium battery power supply of the instrument solves the problem of inability to test on site due to lack of power supply;

2. The testing process is controlled by a microcomputer, which automatically completes self calibration, stable current judgment, data processing, and resistance display;

3. Complete back electromotive force protection function;

4. Charging and power display functions, using large capacity lithium batteries to meet on-site continuous testing needs;

5. The longitudinal test of the DC resistance of the on load tap changer can be completed with one power supply;

6. Fast measurement speed and accurate and stable measurement data;

7. Features such as easy operation, high precision, anti-interference, shock resistance, and convenient portability;

8. The LCD screen adopts a new type of LCD with a wide temperature range of -20 ° C to 70 ° C and automatic adjustment of display content contrast.
