8.4 Diode test
- Select the desired function ( ) by means of the rotary switch 8 of the
BENNING MM 1-1/ 1-2/ 1-3.
- Connect the black safety measuring lead to the COM jack J of the
BENNING MM 1-1/ 1-2/ 1-3.
- Connect the red safety measuring lead to the jack for V, , , Hz 9 of the
BENNING MM 1-1/ 1-2/ 1-3.
- Bring the safety measuring leads into contact with the diode connec-
tions 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.
