Diode Test - VOLTCRAFT VC272 Bedienungsanleitung

12.9 Diode test

Make sure that all objects that you wish to measure (including circuit
components, circuits and component parts) are disconnected and dis-
charged.
1. Switch the DMM on and select the
mode .
2. Press SEL/
ode test mode. The diode symbol and
"V" will appear on the display. Press
the button again to switch to the next
mode.
3. Insert the red test lead into the
measurement socket and the black
test lead into the COM measurement
socket).
4. Check the test leads for continuity by
connecting both measuring probes to
one another. A value of approx. 0.000 V should be shown.
5. 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 normal PN junction forward voltage will be shown in volts (V). "OL"
Æ
indicates that the diode is reverse-biased or defective. Try taking the meas-
urement again with the opposite polarity.
6. After taking a measurement, remove the leads from the measured object and
switch the DMM off.
