f) Continuity test
Make sure that all circuit parts, circuits and components and other
objects of measurement are disconnected from the voltage and dis-
charged.
- Switch on the DMM and select measuring range
switch measurement functions. The symbol for continuity test now appears in the
display. Pressing this button again takes you to the next measuring function, etc.
- Plug the red measuring line into the V measuring jack (10) and the black measur-
ing line into the COM measuring jack (9).
- An approximate value of less than 30 Ohm is identified as continuity; in this case
a beep sounds. The measuring range is up to approx. 400 Ohm.
- If "OL." (overload) appears on the display, you have exceeded the measuring
range or the measuring circuit is interrupted.
- Remove the measuring lines from the object to be measured after completion of
the measurement and switch off the DMM.
g) Diode test
Make sure that all circuit parts, circuits and components and other objects of measurement are
disconnected from the voltage and discharged.
- Switch on the DMM and select measuring range
twice to switch measurement functions. The symbol for diode test now appears in
the display. Pressing this button again takes you to the next measuring function,
etc.
- Plug the red measuring line into the V measuring jack (10) and the black measur-
ing line into the COM measuring jack (9).
- Check the measuring lines for continuity by connecting the two measuring prods.
The value must be approximately 0.000 V.
- Connect the two measuring prods with the object to be measured (diode).
- The display shows the continuity voltage "UF" in volt (V). If "OL" appears, the
diode is measured in reverse direction (UR) or the diode is faulty (interruption).
Perform a counter-pole measurement to check.
- Remove the measuring lines from the object to be measured after completion of
the measurement and switch off the DMM.
