symbol) on the BENNING MM 6.
- Using the blue button  on the BENNING MM 6, switch to diode testing
(press button twice)
- 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.
- Contact the diode connections with the safety test leads and read
the measurement value displayed in the digital display  of the
BENNING MM 6.
- For a normal silicone diode located in flow direction, the flow voltage
between 0.500 V and 0.900 V is displayed. If "000" appears in the display,
there may be a short circuit in the diode. If "1" appears in the display, there
may be an interruption in the diode.
- For a diode located in the non-conducting direction "OL" appears. If the
diode is defective, "000" or other figures appear.
See fig. 7:
8.5 Continuity testing with buzzer
- With the rotating switch , select the desired function (Ω/ buzzer and diode
symbol) on the BENNING MM 6.
- Using the blue button  on the BENNING MM 6, switch to continuity test
(press button once)
- 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.
- Contact the measuring points with the safety test leads. If the test lead
resistance between the COM socket  and the socket  for V, Ω, Hz on
the BENNING MM 6 is lower than 30 Ω the built-in buzzer is activated.
See fig. 8:

8.6 Capacitance 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!
- With the rotating switch , select the desired function on
BENNING MM 6.
- Determine the polarity of the capacitor and discharge it completely.
- 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.
- Contact the discharged capacitor with the safety test leads observing
correct polarity. Read the measurement value on the digital display  of
the BENNING MM 6.
See fig. 9:
8.7 Frequency measurement
- With the rotating switch , select the desired function (Hz) 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. Remember the minimum sensitivity for frequency
measurements using the BENNING MM 6!
- Contact the measuring points with the safety test leads and read the
measurement result on the digital display  on the BENNING MM 6.
See fig. 10:
