To test a diode out of a circuit, connect the Meter as follows:
1. Insert the red test lead into the VΩmA°C°F 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 measured value shows on
the display.
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 to the proper terminals as said above to avoid error
display. The LCD will display "1" indicating open-circuit for wrong con-
nection. 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 testing leads and the circuit under test, and remove the
test leads from the Meter terminals.
To test for continuity, connect the Meter as below:
1. Insert the red test lead into the VΩmA°C°F terminal and the black test
lead into the COM terminal.
2. Set the rotary switch to
3. Connect the test leads across with the object being measured. The buzzer
sounds if the resistance of a circuit under test is less than approximately
70Ω.
Note
• The LCD displays 1 indicating the circuit being tested is open.
• When continuity testing has been completed, disconnect the connection
