8. Measuring with the BENNING IT 105

8.1 Preparations for measuring

Operate and store the BENNING IT 105 only at the specified storage and operating temperatures. Avoid
continuous insulation.
- Check the nominal voltages and nominal current on the safety measuring leads.
- Strong sources of interference in the vicinity of the BENNING IT 105 might lead to unstable readings
and measuring errors.
Before starting the installation tester, always check it as well as all measuring leads and

wires for signs of damage.
8.1.1

Switching the BENNING IT 105 ON/OFF

- Turn the rotary switch 1 from position "OFF" F to the desired measuring function to switch on the
BENNING IT 105.
