8.3 Resistance measurement
- Use the rotating switch
J
to select the required function (Ω, ,
,
) on the
BENNING MM 12.
- Connect the black safety measuring lead to the COM socket
L
on the BENNING MM 12.
- Connect the red safety measuring lead to the socket
K
on the BENNING MM 12.
- Connect the safety measuring leads to the measuring points. Read the measurement value
displayed in the digital display
1
of the BENNING MM 12.
See figure 6: Resistance measurement
8.4 Diode testing
- Use the rotating switch J to select the required function (Ω, ,
,
) on the
BENNING MM 12.
- Press the
Function
key 5 (down/ ▼) of the BENNING MM 12 to switch over (press twice)
to the diode test ( ).
- Connect the black safety measuring lead to the COM socket
L
on the BENNING MM 12.
- Connect the red safety measuring lead to the socket
K
on the BENNING MM 12.
- Contact the diode connections with the safety measuring leads. Read the measurement
value displayed in the digital display
1
of the BENNING MM 12.
- For a normal silicone diode located in flow direction, the flow voltage between 0.4 V and
0.8 V is displayed. “OL” indicates a short-circuit or an interruption inside the diode.
- For a diode applied in reverse direction, a negative forward voltage between -0.400 V and
-0.900 V is indicated.
See figure 7: Diode testing
8.5 Continuity testing with buzzer
- Use the rotating switch
J
to select the required function (Ω, ,
,
) on the
BENNING MM 12.
- Press the Function key
5
(down/ ▼) of the BENNING MM 12 to switch over (press once)
to the continuity test ( ).
- Connect the black safety measuring lead to the COM socket
L
on the BENNING MM 12.
- Connect the red safety measuring lead to the socket
K
on the BENNING MM 12.
Connect the safety measuring leads to the measuring points. If the line resistance between
the COM jack
L
and the jack
K
falls below the adjustable limiting value (10 Ω to 50 Ω), the
integrated buzzer of the BENNING MM 12 sounds.
See figure 8: Continuity testing with buzzer
8.6 Capacity measurement

Discharge capacitors fully before measurement! Never apply voltage to the
sockets for capacitance measurement as this may cause irreparable damage
to the unit. A damaged unit may represent an electrical hazard!
- Use the rotating switch
J
to select the required function (Ω, ,
,
) on the
BENNING MM 12.
- Press the Function key
5
(down/ ▼) of the BENNING MM 12 to switch over (press three
times) to the capacity measurement function ( ).
- Determine the polarity of the capacitor and discharge capacitor completely.
- Connect the black safety measuring lead to the COM socket
L
on the BENNING MM 12.
- Connect the red safety measuring lead to the socket
K
on the BENNING MM 12.
- Contact the discharged capacitor with the safety measuring leads observing correct polarity.
Read the measurement value on the digital display 1 of the BENNING MM 12.
See figure 9: Capacity measurement
8.7 Frequency measurement
- Use the rotating switch
J
to select the required function (V AC, mV AC, A AC) on the
BENNING MM 12.
- Press the Function key
5
(down/ ▼) of the BENNING MM 12 to switch over to the fre -
quency measurement function (Hz).
- Connect the black safety measuring lead to the COM socket
L
on the BENNING MM 12.
- Connect the red safety measuring lead to the socket
K
on the BENNING MM 12. Remember
the minimum sensitivity for frequency measurements using the BENNING MM 12!
- Connect the safety measuring leads to the measuring points. Read the measurement value
displayed in the digital display
1
of the BENNING MM 12.
See figure 10: Frequency measurement
8.8 Temperature measurement
- Use the rotating switch
J
to select the required function ( ) on the BENNING MM 12.
- Press the Function key
5
(down/ ▼) of the BENNING MM 12 to switch over to °C or °F.
- Connect the temperature sensor (type K) to the COM jack
L
and to the jack
K
observing
correct polarity.
- Place the contact point (end of the sensor lead) on the point to be measured. Read the
measurement value on the digital display
1
of the BENNING MM 12.
