To test a diode out of a circuit, connect the Meter as follows:
1.
Insert the red test lead into the
terminal and the black test lead into the
COM
terminal.
2.
Set the rotary switch to
.
3.
For forward voltage drop readings on any semiconductor component, place the red test lead on
the component’s anode and place the black test lead on the component’s cathode. The polarity of
red test lead is “+” while black test lead is “-“.
4.
The measured value shows on the display.
Note
Ɣ
In a circuit, a good diode should still produce a forward voltage drop reading of 0.5V to 0.8V;
However, the reverse voltage drop reading can vary depending on the resistance of other pathways
between the probe tips.
Connect the test leads to the proper terminals as said above to avoid error display.
