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

Cterminal and

the black test lead into the COM terminal.

2. Set the rotary switch to
