Measuring with BENNING MM 3

8.1 Measurement preparation
The BENNING MM 3 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 3 correspond specifically
to the rated voltage and current of the BENNING MM 3.
- 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 3 is used near strong noise generating sources, the
display may become unstable and measurement errors may arise.
8.2 Voltage and current measurement

To avoid electrical shock, observe the maximum rated voltage
to earth ground!
The maximum rated voltage that should be applied between any of the following
terminals of the BENNING MM 3 and earth ground is 600 V.
- COM terminal 
- Input terminal for V, Ω, and Hz 
- Input terminal for µA/ mA range 
- Input terminal for 20 A range 
Electrical hazard! Maximum permissible circuit voltage for
current measurement is 500 V! If a safety fuse blows at a

voltage above 500 V the BENNING MM 3 could be damaged.
A damaged tester presents an electrical shock hazard to the
user!
8.2.1 Voltage measurement
- Select the appropriate range with the rotary switch  of the
BENNING MM 3.
- Use the selector switch  of the BENNING MM 3 to select the required
