![]() ![]() If the multimeter deflects in both conditions the diode is FAULTY.If multimeter deflects only in one condition, the diode is OK.Note down the deflection of multimeter again.Condition 2: Now reverse the connections.Note down the deflection of multimeter.Condition 1: Connect RED probe to anode, BLACK probe to cathode.Procedure to check the condition of diode and go no-go condition Procedure to check the diode for faulty or OK condition Refer the following diagram for connections.And the terminal connected to BLACK probe is cathode.Now if the multimeter deflects, the terminal connected to RED probe is anode.If the multimeter DOES NOT DEFLECT, reverse the probes connections.Connect two probes to two terminals of diode, AT RANDOM.RED probe is positive and BLACK probe is negative.Take a multimeter and put it in ohmmeter range.So to check the diode there are two procedures as discussed below. When you pick up a diode from your stock, sometimes the cathode marking band on the body of diode, may be wiped out, so its difficult to find our the anode and cathode just by looking at it.Īlso when you are troubleshooting an electronic circuit, like a TV, DVD player, etc., and if you doubt a particular diode in the circuit, then after de-soldering it, you need to check it for its go no-go condition. How to find out the anode & cathode using a multimeter?ĭiodes are very cheap in cost, so it is a general thing that every electronic hobbyist has large number of diodes in his/her stock.What is Forward & Reverse Biasing of PN Junction?. ![]() What is Conductor, insulator & semiconductor?. ![]()
