C. Testing Diodes
(see figure 5)
Warning
To avoid damages to the Meter or to the devices
under test, disconnect circuit power and discharge
all the high-voltage capacitors before testing
diodes.
Use the diode test to check diodes, transistors, and
other semiconductor devices. The diode test sends
a current through the semicondutor junction, then
measure the voltage drop across the junction. A
good silicon junction drops between 0.5V and 0.8V.
To test the diode out of a circuit, connect the Meter
as follows:
Insert the red test lead into the Hz Duty%
terminal and the black test lead
into the
COM
terminal.
