1. Applies to test the DC parameters of Oxide Zinc arrester (voltage dependent resistor), cermet second, third electrode discharge tube, vacuum lightning tube and others over voltage protection components. It also can be considered as stable power source and constant current power supply.
2. With HV short circuit protection, over current protection, high voltage preset, range adjustment functions, HV self discharge time less than 0.5 second.
3. It has self calibration function.
4. LCD display, high precision, strong reliability.
5. Pre-set the measurement range when testing, there will be sound alarm if exceed the measurement range.
6. Choose continuous measurement can make continuous test for mass measured equipments.
7. Panel function is simple, easy to operate.
8. Light in weight, easy to carry.
