If the beeper is enabled during diode test, the multimeter will beep briefly
for a normal junction and sound continuously for a shorted junction, below
0.050 V. See "Changing the beep frequency"
beeper.
Reverse the probes (as shown in
the voltage across the diode again. Assess the diode
according to the following guidelines:
• A diode is considered good if the multimeter displays
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
in both forward and reverse bias modes.
