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