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.
- Switch on the DMM and select the desired mode
- P lug the red lead into the Ω terminal (G) and the black lead
into the COM terminal (H).
- I f 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.
