How to Test Diodes with a Digital Multimeter | Fluke
A diode is best tested by measuring the voltage drop across the diode when it is forward-biased. A forward-biased diode acts as a closed switch, permitting current to flow. A multimeter’s Diode Test mode produces a small voltage between test leads.

How To Test a Diode - Learning about Electronics
How to Test a Diode with the Ohmmeter of a Multimeter. A very good test you can do is to check a diode with your multimeter set to the ohmmeter setting. This is a simple test we can do to check whether it is good, open, or shorted. So we take the ohmmeter and place it across the leads of the diode. The orientation is very important.
