1. There are a variety of output voltages (2500V,5000V,10000V). Resistance range measuring range up to 0 ~ 400GΩ. Resistance measuring range can be automatically converted, and have the corresponding instructions.

2. Insulation resistance is simultaneously displayed in two ways:  change range of insulation resistance can be easily observed by mechanical pointer; digital display has measurement accurate results.

3. With embedded and real-time operation of industrial microcomputer software system, high degree of automation and anti-interference ability, equipment can be automatically calculated absorption ratio and the polarization index, without human intervention. 

4. All measurement results have anti-power-down function. It can store 19 consecutive measurements. 

5. The built-in residual high-voltage discharge circuit can automatically release the residual pressure to the device under test after the test is completed.

6. Suitable for AC and DC. Rechargeable battery and AC adapter are configured. 

7. Meter with portable design for easy field operation. 

8. High voltage short circuit current ≥ 1mA
