How do you test a zener diode
WebTo resistance-test the Zener diode, you have to use the multimeter to check the resistance in both directions. Step One: Remove or isolate the Zener diode from the circuit, if applicable. Step Two: Test the resistance in the ‘positive bias’ configuration. Place the negative/black lead of the multimeter on the cathode- the side of the Zener ... WebThe Diode Test procedure is conducted as follows: Make certain a) all power to the circuit is OFF and b) no voltage exists at the diode. Voltage may be present in the... Turn the dial …
