8. Measuring with 01
8.1 Measurement preparation
The MN 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 01 correspond specifically
to the rated voltage and current of the 01 .
- Inspect the test leads for damaged insulation. If the insulation is damaged,
the test leads should be discarded immediately.
