1.1 General introduction
The tester can record switch operation waveform in overall process. The longest time is 6.4s.It can test various parameters such as transition waveform, transition time, transition resistance and three phase synchronization one time and analyze results automatically. It has power-off protection, over-voltage protection, perpetual clock and high-speed printing.
