  • Product Features

1、Insulation resistance range 20TΩ @ 20 kv


2、Short circuit current can be adjusted, maximum 5mA (Can be ordered as high as 10mA, short circuit current products).


3、Automatic display polarization index (PI), induced electric absorption test values than (DAR), and can test the leakage current and capacitance.


4、Anti-jamming performance is superior, the interference current reaches 2 mA, still ensure accuracy of test instruments.


5、2 methods for power: use of lithium ion batteries, battery life can be up to 4 hours (10000V @ 100MΩ).


6、Insulation resistance simulation column.


7、Digital filtering functions, external influence deviation display value causing mitigation point using filter function.


8、Perfect protection function, and the spare fuse prompt functions.
