IRT-C Insulation resistance tester

The insulation resistance tester IRT-C is engineered for accurate
measuring of LV-installations and appliances according the EN 61157
regulation. The tester has been developed to measure voltage and
continuity.
Also insulation resistance of high sensitive parts and even heavy machines
or ground cables can be measured easily with the four different test
voltages.

Measurements

• Insulation resistance with test voltages of:
  - 100 VDC
  - 250 VDC
  - 500 VDC
  - 1000 VDC
• Partial resistance of earth connection (200 mA)
• Voltage
