and discharge all high-voltage capacitors before measuring diodes and continuity.
Never attempt to input over 60V in DC or 30V rms in AC to avoid personal dangerous.
Testing Diodes
Use the diode test to check diodes, transistors, and other semiconductor devices.
The diode test sends a current through the semiconductor junction, and then measures the
voltage drop across the junction. A good silicon junction drops between 0.5V and 0.8V.
To test out a diode out of a circuit, connect the Meter as follows:
1. Set the rotary switch to
Ω
range.
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.
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.
