Testing Diodes
Warning
To avoid damages to the Meter or to the
devices under test, disconnect circuit power
and discharge all the high-voltage capacitors
before 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.
