g) Diode Test
make sure that all circuit parts, circuits and components and other objects of
measurement are disconnected from the voltage and discharged.
- Turn the DMM on and select measuring range
.
Press “MODE” button 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 (9) and the black measuring line into the COM
measuring jack (8).
- Check the measuring lines for continuity by connect-
ing 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 (interrup-
tion). 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.
