WebMay 9, 2024 · To test them put a 5 V voltage source and 1k resistor in series and then measure the voltage across the LED. If you see your supply voltage or 0V then the LED is dead, if you see just over 3V the LED is good. Supply voltage or around 0.6V could also indicate the diode is backwards depending upon the exact nature of the part. WebNov 15, 2024 · How to Test a Diode with a Multimeter Connect the black lead to the COM terminal on the multimeter. Connect the red lead to the Ω terminal, unless your particular model differs. Turn the dial to the diode symbol on the multimeter. This allows for electric current to travel in one direction (the arrow) and not the other. Turn the multimeter on.
