8.4 Diode test

- Using the rotary switch  select the required function (
BENNING MM 9/ 10.
- The black safety measuring lead has to be connected to the COM jack 
on the BENNING MM 9/ 10.
- The red safety measuring leads has to be connected to the jack for V, Ω,
µA, , Hz  on the BENNING MM 9/ 10.
- Bring the safety measuring lead into contact with the diode connections, read
the measured value on the digital display  on the BENNING MM 9/ 10.
- 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 "OL" indicate an interruption in the
diode.
- For a diode applied in reverse direction "OL" is displayed. If the diode is
defective, "000" or other values are shown.

8.6 Capacity measurement

Before carrying out capacity measurements discharge
capacitors completely!

Never apply voltage to the capacity measurement jacks!
The appliance can become damaged or even be destroyed! A
damaged appliance may cause an electrical hazard!
- Using the rotary switch  select the required function (
BENNING MM 9/ 10.
- Determine the polarity of the capacitor and discharge capacitor completely.
- The black safety measuring lead has to be connected to the COM jack 
on the BENNING MM 9/ 10.
- The red safety measuring lead has to be connected to the jack for V, Ω, µA,
, Hz  on the BENNING MM 9/ 10.
- The safety measuring leads have to be brought into contact with the dis-
charged capacitor according to its polarity, read the measured value on the
digital display  on the BENNING MM 9/ 10.
see figure 9:
8.7 Frequency measuring
