Testing tips
•
To measure forward-bias diode, connect the other end of the red test
lead to the positive terminal (anode) of the diode and the black test lead
to the negative terminal (cathode). The cathode of a diode is indicated
with a band.
•
The U3606B can display diode forward bias of up to approximately
1.2 V. The forward bias of a typical diode is within the range of 0.3 V to
0.8 V.
•
A diode is considered good if the multimeter displays OPEn 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 U3606B beeps
continuously.
•
A diode is considered open if the multimeter displays OPEn in both
forward and reverse bias modes.
