8.4 Diode test
- Select the desired function (
BENNING MM 1-1/ 1-2/ 1-3.
- Connect the black safety measuring line to the COM jack J of the
BENNING MM 1-1/ 1-2/ 1-3.
- Connect the red safety measuring line to the jack for V, ,
BENNING MM 1-1/ 1-2/ 1-3.
- Bring the safety measuring lines into contact with the diode connections
and read the measured value on the digital display  of the
BENNING MM 1-1/ 1-2/ 1-3.
- For a standard Si diode applied in conduction direction, a conduction voltage
between 0.400 V and 0.900 V is displayed. „000" indicates a short-circuit
inside the diode, „OL" indicates an interruption inside the diode.
- For a diode applied in reverse direction, „OL" is indicated. If the diode is
defective, „000" or other values are indicated.
See figure 7:
8.5 Continuity test with buzzer
