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.
