E. Testing Diodes

(See figure 7)

Warning
To avoid possible damage to the Meter and to the
device under test, disconnect circuit power and
discharge all high-voltage capacitors before testing
diodes.
To avoid personal injury, please do not attempt to
input voltages higher than 60V DC or 30V AC.

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.
