Measurement Operation(8)
Warning
To avoid damage to the Meter or to the equipment
under test, disconnect circuit power and discharge
all high-voltage capacitors before measuring diodes
and continuity.
Testing Diodes
Use the diode test to check diodes, transistors, and other
semiconductor devices. The diode test sends a current
through the semiconductor junction, and then measures
the voltage drop across the junction. A good silicon
junction drops between 0.5V and 0.8V.
To test out a diode out of a circuit, connect the Meter as
follows:
1. Insert the red test lead into the
V
o
Cterminal and
the black test lead into the
COM
terminal.
2. Set the rotary switch to
