Features of this Insulation Resistance Measuring Instrument
1. Insulation resistance range 2TΩ@5kV
2. The short-circuit current can be adjusted up to 3mA.
3. Automatically display the test values of polarization index (PI) and dielectric absorption ratio (DAR), which can test leakage current and capacitance.
4. Excellent anti-interference performance, the test accuracy can be guaranteed even when interference current reaches 2mA.
5. The capacitive test sample discharges quickly to avoid the danger of sparks caused by artificial discharge during cable testing.
6. The instrument has the traditional automatic discharge function, and can display the discharge voltage in real time (there is also an improved product with independent rapid discharge).
7. 2 kinds of power supply methods: when using lithium-ion battery power supply, battery life up to 5 hours (2500V@100M test resistance).
8. It can be charged in use. In the event of a power failure, it can automatically switch from AC power supply to battery power supply.
