– Your multimeter can display diode forward bias of up to approximately 3.1 V. The
NOTE
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.
– If the beeper is enabled during a 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" on page
Reverse the probes (as shown in Figure 2-19) and measure the voltage across the diode
again. Assess the diode according to the following guidelines:
– A diode is considered good if the multimeter displays
– A diode is considered shorted if the multimeter displays approximately 0 V in both
– A diode is considered open if the multimeter displays
