h) Conducting a diode test
Make sure that all objects that you wish to measure (including circuit components, circuits and
component parts) are disconnected and discharged.
- Switch on the DMM and select the desired mode
.
-
PlugtheredleadintotheΩterminal(G)andtheblacklead
into the COM terminal (H).
- Check the measuring leads for continuity by connecting
both measuring probes to one another. A value of approx.
0.000 V should be shown.
- Connect the two measuring probes to the object that you
want to measure (diode). Connect the red lead to the an-
ode (+) and the black lead to the cathode (-).
- The continuity voltage (“UF”) will be shown in Volts (V).
“OL” indicates that the diode is reverse-biased or defec-
tive. Try taking the measurement again in the opposite
polarity.
- After taking a measurement, remove the leads from the
measured object and switch off the DMM.
i) Conducting a continuity test
Make sure that all objects that you wish to measure (including circuit components, circuits and
component parts) are disconnected and discharged.

- PlugtheredleadintotheΩterminal(G)andtheblacklead
into the COM terminal (H).
- Ifthemeasured resistance is equaltoor less than 10Ω,
the multimeter will beep to indicate continuity. The beeps
stopwhentheresistanceexceeds100Ω.Thecontinuitytest
measures resistances of up to 200 Ohm.
- “OL” (overload) indicates that the measuring range has been
exceeded or that the circuit is broken.
- After taking a measurement, remove the leads from the
measured object and switch off the DMM.
