Frequently asked questions

What happens if the measured voltage is above 660 V ac/dc?

The meter will display ">660Vac/dce" on the screen.

How is the Polarization Index (PI) calculated?

PI is calculated by dividing the insulation resistance measured at the 10-minute mark by the resistance measured at the 1-minute mark.

What indicates a good insulation reading for PI or DAR?

A reading where PI is bigger than 2 or DAR is bigger than 1.3 indicates good insulation.
