1. Performance characteristics

 It is applicable to the measurement of DC parameters of overvoltage protection components such as zinc oxide arrester (varistor), metal ceramic two - and three electrode discharge tubes, vacuum surge arresters, etc. It can also be used as a voltage stabilizing and constant current power supply for other purposes.

 It has high voltage short circuit protection, over-current protection, high voltage preset, range adjustment and other functions, and the high voltage self discharge time is less than 0.5 seconds.

 Self check function.

 The measurement data is digitally displayed by 3 1/2 LCD with high accuracy and reliability.

 During the measurement, the measuring range can be set in advance, and the audible prompt for the over range test can be given during the measurement process, which is applicable to device grouping and inspection discrimination.

 Continuous measurement can be selected to conduct continuous test on batch samples.

 The panel function is simple and easy to operate.

 Light weight, easy to carry.
