Measuring with the BENNING MM 4

8.1 Preparation for measurement
Store and use the BENNING MM 4 only under the correct temperature condi-
tions specified. Always avoid prolonged exposure to sunlight.
- Check nominal voltage and current data on the black safety test lead and red
test probe. The black test lead and the red test probes supplied correspond
to the BENNING MM 4 in nominal voltage and nominal current.
- Check insulation of the safety test lead and red test probe. If the insulation
is damaged, discard the lead and test probes immediately.
- Check the continuity of the safety test lead. If the conductor in the safety
test lead is interrupted, discard the safety test lead immediately.
- Before selecting another function at the sliding switch 2 or function button
4, the safety test lead and red test probes must first be disconnected from
the measurement point.
- Strong sources of interference in the vicinity of the BENNING MM 4 may
cause unstable or incorrect readings.

8.2 Voltage measurement


Always observe the maximum voltage to earth potential!
Electrical hazard!
The maximum voltage which may be applied to the sockets of the Multimeter with
- COM socket 7, marked black,
- V-Ω socket (positive) 8 for voltage and resistance measurements, continu-
ity and diode testing (marked red) of the BENNING MM 4 with reference to
earth potential is 600 V.
- Plug the black safety test lead into the COM socket 7 (black).
- Plug the red test probe into the V-Ω socket 8 (red).
- With the slide switch 2, the function button 4 and the RANGE button 6 of
the BENNING MM 4, select the desired range.
- Contact the measurement points with the black safety test lead and the red
test probe. The measured value appears in the digital display 3.
Note:
In low voltage ranges, the zero volts display does not appear due to interference
when the safety test leads are open. Check that the BENNING MM 4 is fully
functional by short-circuiting the test probe.
