The special functions of our instrument test software and hardware version

1) Short circuit protection test (Refers to the microsecond level of real short circuit protection test).

2) Drop test (It means that the signal line of a section can be detected when it falls off or breaks).

3) Selfpower consumption test (Refers to the true and accurate self power consumption of each section).

4) Equalizing current and voltage (Can accurately grasp the equalizing current and voltage)     

The above technology is the result of many years of experience and research and development of our engineers and technicians, which is different from other instruments that need to be  upgraded frequently.
