8. Measuring with the BENNING MM 6
8.1 Preparation for measurement
Store and use the BENNING MM 6 only under the correct temperature
conditions stated. Always avoid longer exposure to sunlight.
- Check the rated voltage and rated current stated on the safety test leads.
The safety test leads supplied with the unit are suitable for the rated voltage
and current of the BENNING MM 6.
- Check the insulation of the safety test leads. If the insulation is damaged in
any way, do not use the leads.
- Check the continuity of the safety test leads. If the conductor in the safety
test lead is interrupted, do not use the leads.
- Before selecting another function with the rotating switch
, always
disconnect the safety test leads from the measuring point.
- Sources of strong current in the vicinity of the BENNING MM 6 may cause
unstable or incorrect readings.
8.2 Voltage and current measurement
Always observe the maximum voltage to earth potential! Electrical hazard!
The maximum voltage which may be applied to the sockets
- COM- socket
- socket for V, Ω, Hz
- socket for mA range
and the
- socket for 10 A range
of the BENNING MM 6 to earth is 1000 V.
Electrical hazard!
Maximum switching-circuit voltage for current measurement,
500 V! If the fuse triggers over 500 V, the unit may be damaged.
A damaged unit may represent an electrical hazard!
8.2.1 Voltage measurement
- With the rotating switch
, select the desired function (V) on the
BENNING MM 6.
- With the blue button
on the Benning MM 6, select the type of voltage to
be measured (DC or AC voltage)
- Connect the black safety test lead to the COM socket
on the
BENNING MM 6.
- Connect the red safety test lead to the socket
for V, Ω, Hz on the
BENNING MM 6.
- Connect the safety test leads to the measuring points. Read the measurement
value displayed in the digital display
of the BENNING MM 6.
See fig. 2:
DC-voltage measurement
See fig. 3:
AC-voltage measurement
8.2.2 Current measurement
- With the rotating switch
, select the desired range and function (mA or A)
on the BENNING MM 6.
- With the blue button
on the Benning MM 6, select the type of current to
be measured (DC or AC current).
- Connect the black safety test lead to the COM socket
on the
BENNING MM 6.
- Connect the red safety test lead to the socket for mA range,
for current
up to 400 mA or to the socket for the 10 A range,
for currents greater than
400 mA up to 10 A on the BENNING MM 6.
- Connect the safety test leads to the measuring points. Read the measurement
value displayed in the digital display
of the BENNING MM 6.
See fig. 4:
DC-current measurement
See fig. 5:
AC-current measurement
8.3 Resistance measurement
- With the rotating switch
, select the desired function (Ω) on the
BENNING MM 6.
- Connect the black safety test lead to the COM socket
on the
BENNING MM 6.
- Connect the red safety test lead to the socket
for V, Ω, Hz on the
BENNING MM 6.
- Connect the safety test leads to the measuring points. Read the measurement
value displayed in the digital display
of the BENNING MM 6.
