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.
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
however, the reverse-bias read-
ing can vary depending on the
resistance of other pathways
between the probe tips.
