Features and Advantages
1、Intuitive reading: the instrument adopts digital LCD meter to directly display the test values of high voltage, instrument voltage, low voltage current and high voltage current, which is convenient for test observation and recording.
2、Measurement accuracy: full digital processing, built-in precision mathematical model, high measurement accuracy and accurate test value.
3、Accurate protection function: full digital processing, the setting of overcurrent protection value, timing voltage and overvoltage protection value are all realized by digital, making the protection more accurate.
4、Automatic timing: the instrument has the timing trigger function. The equipment automatically timing according to the set voltage value, making the timing more accurate and effective.
5、Safety grounding inspection: the instrument has the safety grounding inspection function. When the instrument is not grounded safely during the test, the closing test is not allowed.
6、Convenient to carry: small size, light weight, only 30%~70% of the volume of similar products, very convenient to carry.
