• Checking of test objects for absence of voltage
Applicable Regulations and Standards
Characteristic Values
Measurement of Insulation Resistance
Nominal Range per EN 61557-2: 0.100 M – Rmax*
* The Rmax value depends on the selected test voltage:
Nominal voltage of 50 to 99 V Rmax = 1.999 G
Nominal voltage of 100 to 249 V Rmax = 3.999 G
Nominal voltage of 250 to 1000 V Rmax = 9.999 G
