8. Measuring with the BENNING MM 1‑1/ 1‑2/ 1‑3
8.1 Preparing the measurement
Operate and store the BENNING MM 1-1/ 1-2/ 1-3 at the specified storage and
operating temperatures only!
Do not permanently expose the device to sunlight.
- Check stated nominal voltage and nominal current on the safety measuring
leads. Nominal voltage and current of the enclosed safety measuring leads
comply with the respective values of the BENNING MM 1-1/ 1-2/ 1-3.
- Check insulation of the safety measuring leads. If the insulation is damaged,
the safety measuring leads must be replaced immediately.
- Check the safety measuring leads for continuity. If the conductor in the
safety measuring lead is interrupted, replace the safety measuring leads
immediately.
- Before selecting another function by means of the rotary switch
8
, discon-
nect the safety measuring leads from the measuring point.
- Strong sources of interference in the vicinity of the BENNING MM 1-1/ 1-2/ 1-3
might involve unstable readings and measuring errors.
8.2 Voltage and current measurement
Do not exceed the maximum permitted voltage with respect to
earth potential! Electrical danger!
