BENNING MM 11
26
- jack for 10 A range
of the BENNING MM 11 against ground, amounts to 1000 V.
Electrical danger!
Maximum circuit voltage for a measured current of 600 V! In
the case of a safety triggering in excess of 600 V, damage to the
appliance may be caused. A damaged appliance may represent
an electrical hazard!
8.2.1 Voltage measuring
- Use the rotary switch
to select the required function (V) on the
BENNING MM 11.
- Using the button (blue)
select the voltage type to be measured on the
BENNING MM 11: direct current (DC) or alternating current (AC).
- The black safety measuring lead has to be connected to the COM jack
on the BENNING MM 11.
- The red safety measuring lead has to be connected to the jack for V,
, Hz,
°C,
on the BENNING MM 11.
-
Bring the safety measuring leads into contact with the measuring points, read
the measured value on the digital display
unit of the BENNING MM 11.
See figure 2:
Direct voltage measurement
See figure 3:
Alternating voltage measurement
8.2.2 Current measuring
- Use the rotary switch
to select the required range and function (mA or A)
on the BENNING MM 11.
- Using the button (blue)
select the voltage type to be measured on the
BENNING MM 11: direct current (DC) or alternating current (AC).
- The black safety measuring lead has to be connected to the COM jack
on the BENNING MM 11.
- The red safety measuring lead has to be connected to the jack for the mA
range,
for currents up to 200 mA or with the jack for 10 A range
for
currents greater 200 mA to 10 A on the BENNING MM 11.
-
Bring the safety measuring leads into contact with the measuring points, read
the measured value on the digital display
unit of the BENNING MM 11.
See figure 4:
Direct current measurement
See figure 5:
Alternating current measurement
8.3 Resistance measurement
-
Using the rotary switch
select the required function (Ω) on the
BENNING MM 11.
- If necessary, use the button (blue)
to select the function LVΩ
(reduced
measurement voltage: 0.6 V).
- The black safety measuring lead has to be connected to the COM jack
on the BENNING MM 11.
- The red safety measuring lead has to be connected to the jack for V,
Ω
, Hz,
°C,
on the BENNING MM 11.
-
Bring the safety measuring leads into contact with the measuring points, read
the measured value on the digital display
unit of the BENNING MM 11.
See figure 6:
Resistance measurements
8.4 Diode test
- Use the rotary switch
to select the required function (
) unit of the
BENNING MM 11.
- The black safety measuring lead has to be connected to the COM jack
on the BENNING MM 11.
- The red safety measuring lead has to be connected to the jack for V,
Ω
, Hz,
°C,
on the BENNING MM 11.
- Bring the safety measuring leads into contact with the diode connec-
tions, read the measured value on the digital display
unit of the
BENNING MM 11.
- For a standard Si diode applied in conduction direction the conduction volt-
age between 0.400 V to 0.900 V is displayed. The display “000” indicates a
short circuit in the diode, display values > 2 V indicate an interruption in the
diode.
- For a diode applied in reverse direction “OL” is displayed. If the diode is
defective, values < 2 V are shown.

Diode test
8.5 Continuity testing with buzzer
- Use the rotary switch
to select the required function (
) on the
BENNING MM 11.
- Using the button (blue)
carry out the switchover to continuity testing on
