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.
To test the diode out of a circuit, connect the
Meter as follows:
1. Insert the red test lead into the
terminal and the black test lead into the
COM terminal.
2. Set the rotary switch to and press
SELECT button to select measurement
