F) Diode Test ( ) - VOLTCRAFT VC191 Operating Instructions Manual

f) Diode test (
Make sure all circuit parts, circuits, components, and other objects of measurement
are disconnected from the voltage supply and fully discharged.
The test voltage is approximately 3V.
1. Set the function dial to
2. Short press the SEL/PEAK button 3x to select
diode test, "
3. Connect the test leads to the terminals:
- Red test lead to the
- Black test lead to the COM terminal.
4. Check the lines for continuity by connecting the
two test leads. The value should be approximately
0.000 V.
5. Connect the test lead probes to the correct test
points on the diode.
- "OL" will appear on the display if the polarity is
reversed or if the circuit is open.
- The normal PN junction forward voltage is ap-
prox. 500 to 800 mV.
6. When finished measuring, disconnect the test leads and switch the power OFF.
