3.2.5 Diode Test

To avoid electrical shock and/or damage to the instrument, disconnect circuit
power and discharge all high-voltage capacitors before testing diodes.
To test a diode out of a circuit (set up the Meter as shown in Figure 3-5):
1. Set the rotary switch to
2. Press the SELECT key to select Diode Test.
3. Connect the black and red test leads to the COM and VΩ terminals respectively.
4. For forward-bias readings on any semiconductor component, place the red test lead on the com-
ponent's anode and place the black test lead on the component's cathode.
5. The meter will show the approx. forward voltage of the diode.
In a circuit, a good diode (Si)
should still produce a forward
bias reading of 0.5V to 0.8V;
however, the reverse-bias read-
ing can vary depending on the
resistance of other pathways
between the probe tips.
