Performance Features
Suitable for measuring DC parameters of overvoltage protection components such as zinc oxide arresters (varistors), metal ceramic two- and three-electrode discharge tubes, and vacuum surge arresters. It can also be used as a stabilized voltage or constant current power supply for other applications.
Ø Features high voltage short-circuit protection, overcurrent protection, high voltage preset, range adjustment, etc. High voltage self-discharge time is less than 0.5 seconds.
Ø Has self-test function.
Ø Measurement data is displayed on a 3½ LCD digital display, with high accuracy and good reliability.
Ø During measurement, the range can be preset, and an audible alarm is provided for over-range testing, suitable for component grouping and inspection discrimination.
Ø Select continuous measurement for uninterrupted testing of batch samples.
Ø Simple panel functions for easy operation.
Ø Lightweight and portable.
