3 Reverse the probes (as shown in
Figure 2-20
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
Keysight U1271A/U1272A User's Guide
Your multimeter can display diode forward bias of up to approximately 3.1 V.
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.
the diode again. Assess the diode according to the following guidelines:
– A diode is considered good if the multimeter displays
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
and reverse bias modes.
