The forward-bias of a typical diode is within the range of 0.3 V to 0.8 V;
however, the reading can vary depending on the resistance of other
pathways between the probe tips.

beeper.
– A diode is considered good if the multimeter displays OL in reverse-bias
mode.
– A diode is considered shorted if the multimeter displays approximately 0 V
in both forward- and reverse-bias modes, and the multimeter beeps
continuously.
– A diode is considered open if the multimeter displays OL in both forward-
and reverse-bias modes.
