Disconnect circuit power and discharge all high-voltage capacitors before testing
diodes to avoid damaging the multimeter.
To test a diode, switch the circuit power off, and remove the diode from the
circuit. Then proceed as follows:
1 Press
2 Connect the red and black test leads to the input terminal as shown in
3 Connect the red test lead to the positive terminal (anode) of the diode and
The cathode of a diode is indicated with a band.
4 Read the display.
5 Reverse the probes and measure the voltage across the diode again (refer to
• Measurement method:
• Response time:
• Gate time:
• Input protection:

• A diode is considered good if the multimeter displays OL in reverse bias
• A diode is considered shorted if the multimeter displays approximately
• A diode is considered open if the multimeter displays OL in both forward
