High Precision Intelligent Lightning Protection Component Tester With LCD Display
Introduction
This instrument is used to test the DC parameters of Oxide Zinc voltage dependent resistor
( varistor/ MOV), ceramic 2/3-electrode surge arrester, gas discharge tube and other Surge
Protective Devices. It also can be used as stable power source or constant current power supply.
Features
HV short circuit and over current protection, high voltage preset, range adjustment functions
HV self discharge time less than 0.5 second.
Self check function.
LCD display, high precision, strong reliability.
Measurement range can be preset, sound alert when exceed the acceptable range.
Continuous measurement for a batch of test objects
Simple panel for easy operation
Light in weight, easy to carry
