1. Automatic measurement, convenient and quick operation

The instrument adopts the automatic control principle of the closed-loop adjustment precision of 1mA current and 0.75 times the DC reference voltage, using microcomputer control measurement process, leakage current DC reference voltage of arrester only needs to measure the Zinc Oxide 1mA press a button to automatically when the DC reference voltage and 0.75 times of the process takes about 15 seconds very suitable for mass measurement.

2. Integrated structure, small volume, light weight

The instrument consists of high voltage power supply, measurement and control system. All the components are concentrated in a case. It has the characteristics of small volume, light weight and so on.

3. Special process design, simple connection
