g) Diode test
Make sure that the circuit components, circuits and components to be meas-
ured or any other measuring objects are voltage-free and discharged.
- Turn on the DMM and select the measuring range . Press
the SELECT key twice to switch to the correct measuring
function. The display shows the symbol for diode test. Press-
ing the key again will switch to the next measuring function,
etc.
- Insert the red test lead into the V test socket (10) and the
black test lead into the COM test socket (9).
- Check the test leads for continuity by connecting the test
prods to one another. The device should then register a value
of approx. 0.000 V.
- Connect the test prods to the measuring object (diode).
- The display shows forward voltage “UF” in volt (V). If the
display shows OL, the diode is measured in reverse direc-
tion (UR) or the diode is defective (interrupted). For checking
purposes, conduct a measurement on the opposing poles. A
beep sounds in case of forward voltages <0.1 V.
- Remove the test leads from the measuring object and turn off
the DMM after measurement.
