i) Diode test
Ensure that all objects that you want to measure (including circuit components, circuits and com-
ponent parts) are disconnected and discharged.
- Switch the DMM on and select the mode
- Press "SELECT" twice to switch to diode test mode. The diode
symbol and "V" will appear on the display. Press the button
again to switch to the next mode.
- I nsert the red test lead into the Ω measurement socket (G) and
the black test lead into the COM measurement socket (H).
- Check the test leads for continuity by connecting both measur-
ing probes to one another. A value of approx. 0.000 V should
be shown.
- Now connect the two measuring probes to the object to be
measured (diode). The red test lead to the anode (+), the black
test lead to the cathode (-).
- The continuity voltage "UF" will be shown in volts (V). "OL"
indicates that the diode is reverse-biased or defective. Try tak-
ing the measurement again with the opposite polarity.
- After taking a measurement, remove the leads from the meas-
ured object and switch the DMM off.
j) Continuity test
Ensure that all objects that you want to measure (including circuit components, circuits and com-
ponent parts) are disconnected and discharged.
- Switch the DMM on and select the mode
- Press the "SELECT" button once to switch to the mode. The
continuity test symbol and the Ω symbol will appear on the
display. Press the button again to switch to the next mode.
- I nsert the red test lead into the Ω measurement socket (G) and
the black test lead into the COM measurement socket (H).
- I f the measured resistance is equal to or less than 10 Ω, the
multimeter will beep to indicate continuity. There is no further
beeping from >100 Ω. The continuity test measures resist-
ances of up to 600 Ω.
- "OL" (overload) indicates that the measurement range has
been exceeded or that the circuit is broken.
- After taking a measurement, remove the leads from the meas-
ured object and switch the DMM off.
