To avoid damages to the Meter or to the devices under

test, disconnect circuit power and discharge all the

high-voltage capacitors before measuring diodes and

continuity.

Testing Diodes

Warning

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 a diode out of a circuit, connect the Meter as follows:

Insert the red test clip into the terminal and

the black test clip into the COM terminal.

Set the rotary switch to .

For forward voltage drop readings on any semiconductor

component, place the red test clip on the component’s

anode and place the black test clip on the component’s

cathode.

The display shows the diode forward voltage drop’s

nearest value.
