The test instrument permits the measurement of insulation resistance with test voltages between 50 and 1000 V in accordance with VDE 0413-1,-2 (EN 61557-1, 2). The measuring range runs from 100 kΩ to 1 GΩ.

• Measurement of insulation resistance at voltage-free devices and equipment, up to 1000 V depending on the variant
• Measurement of surge protection devices, up to 1000 V depending on the variant
• Checking of test objects for the absence of voltage
