Note
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 properly as said above to avoid error display. The LCD
will display “OL” indicating open-circuit for wrong connection. The unit of diode
is Volt (V), displaying the positive-connection voltage-drop value.
When diode testing has been completed, disconnect the connection between
the leads and the circuit under test.

2. Press SELECT button to select diode test.
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 LCD displays the nearest value of diode forward voltage drop.
