Diode test
To test the diode, turn the rotary
switch to position "
".
Then connect the measuring
contacts to the diode.
The measured value acquired
for the forward voltage appears
on the display.
If "1" appears on the display
instead of a measured value,
the diode has either been tested
in the reverse direction or is faulty.
If 0.0 V is measured, the diode is
faulty or a short-circuit has occurred.
