8. Measuring by means of 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
lines. Nominal voltage and current of the enclosed safety measuring lines
comply with the respective values of the BENNING MM 1-1/ 1-2/ 1-3.
- Check insulation of the safety measuring lines. If the insulation is damaged,
the safety measuring lines must be replaced immediately.
- Check the safety measuring lines for continuity. If the conductor in the
safety measuring line is interrupted, replace the safety measuring lines
immediately.
- Before selecting another function by means of the rotary switch 8,
disconnect the safety measuring lines 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!
The highest voltage which may be applied to the
- COM jack J
- jack for V, Ω,
- jack for the 10 A range K (BENNING MM 1-2/ 1-3)
of the BENNING MM 1-1/ 1-2/ 1-3 against ground is 1000 V.
Electrical danger!
Maximum circuit voltage for a measured current of 500 V! In

case of fuse triggering at values above 500 V, damages of the
device might be involved. A damaged device might represent
an electrical hazard!
