Measuring with the BENNING CM 1-3

8.1 Preparing the measurement

Operate and store the BENNING CM 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 CM 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 2, discon-
