Do this by connecting the multimeters positive or red lead on the anode side of the diode which is unmarked. Most digital multimeters have a diode check mode.

Measure the forward voltage drop across the zener diode.

Testing a zener diode with a digital multimeter. The orientation is very important. Multimeter diode testing diodes can be tested using a multi meter. Place the negative or black lead on the cathode side of the diode which is marked by a stripe.

The diode test procedure is conducted as follows. Let us see how to test an led using a digital multimeter. Set the multimeter selector switch in low resistance value.

There are however a number of points to remember when testing diodes. Increase the supply voltage gradually to the zener diode and note the meter reading displayed on screen. So we take the ohmmeter and place it across the leads of the diode.

To enable this mode turn the dial to the symbol for diode a black arrow pointing to a vertical line. The method of testing a diode with an analog meter is quite straightforward. This is a simple test we can do to check whether it is good open or shorted.

Identify the terminals anode and cathode of the led. Typically used only if a multimeter is not equipped with a diode test mode. It is normally the resistance of the diode in both forward and reverse directions that is tested.

Connect the positive terminal of the diode to the positive terminal of the multimeter. The multimeter then displays the voltage drop when the test leads are connected across a diode when forward biased. Test a zener diode with an ohmmeter of a multimeter.

Make certain a all power to the circuit is off and b no voltage exists at the diode. A very good test you can do is to check a zener diode with your multimeter set to the ohmmeter setting. Check for a diode check mode.

Place the multimeter selector in diode mode. In some cases it may be necessary to remove one end of the diode from the circuit in order to test the diode. Digital multimeters can test diodes using one of two methods.

If the led is working properly then it glows otherwise the led is defective. In both of digital or analog multimeter set the meter on dc voltage test mode by turning the rotary switch of multimeter. Connect the probes of the meter to led such that it is forward biased.

If your multimeter does not have this mode test resistance instead. Testing of a diode using analog multimeter step by step instructions. Almost always the best approach.

Connect the negative terminal of the diode to the negative terminal of the multimeter. A multimeters diode test mode produces a small voltage between test leads.
