Measuring with BENNING MM 1

8.1 Measurement preparation
The BENNING MM 1 must be used and stored only at the indicated storage and
working temperatures, avoid exposure to continuous sunlight.
- Check the rated voltage and current indications on the test leads. The
safety test leads provided with the BENNING MM 1 correspond specifically
to the rated voltage and current of the BENNING MM 1.
- Inspect the test leads for damaged insulation. If the insulation is damaged,
the test leads should be discarded immediately.
- Check test lead continuity. If the conductor in the test lead is damaged, the
leads should be discarded immediately.
- Remove test leads from circuit to be measured before turning the rotary
switch  to select another function.
- If the BENNING MM 1 is used near strong noise generating sources, the
display may become unstable and measurement errors may arise.
