DIODE TESTING
NOTE
Do not use the diode test functionality while connected to a
live circuit. Doing so will result in incorrect readings and
may engage the internal protection circuitry. Should this
occur, wait 5 minutes before taking further measurements.
To test diodes or other silicon junction devices, a test current is
pushed through the device under test and the resulting voltage is
measured.
Positive test current ows out of the Ω terminal and into the C
terminal
The test current is 100µA.
