D.Testing Diodes
To avoid damage 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
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:
through the semicondutor junction, then measure the
