How to Test a Diode using Digital Multimeter

1) Connect the Positive  Lead of the Meter to the Anode of the Diode

2) Connect the Negative Lead of the Meter to the cathode of the Diode

3) Set the Meter to high Resistance mode such as 1k or above .


4) Damaged Diode will show very Low resistance at Both Forward and Reversed Direction

5) Good Diode will show High resistance in the reversed direction while show low resistance at Forward Biased.
