  • Product Features

1、High current: 

The tester can output sequential high current which overcome the difficulties in instantaneous current of pulsed power. It can effectively Breakdown the oxide layer between the switches and then get more precise results

2、Strong anti-interference ability: 

The last number of test data showed in the LCD screen ranges ±1 even in strong Interference situation

3、Long service life: 

All of the precise resistances used in the tester can reduce The temperature’s impact on the measurement results and military connectors can enhance vibration resistance

4、Convenience: 

Smaller and lighter
