What to measure
(Diode test): Judging the diode (Good or defective)
2)
Measuring procedure
①
Connect the red plug of the test lead to
measuring
terminal and the black one to the COM terminal.
②
Set the function selector to
, then press the SELECT
button to select the diode test.

③
Apply the black test pin to the cathode of the diode, and the
red one to the anode.
④
The display will show the forward voltage drop (forward
biased).
*
Forward biased voltage drop for a good silicon diode is
between 0.400 V to 0.900 V. A reading higher than that
indicates a defective diode. A zero (or close to)reading
indicates a defective diode (shorted). An OL indicates a
defective diode (open).
⑤
Apply the red test pin to the cathode of the diode, and the
black one to the anode.

the diode is good. Any other readings indicate the diode is
defective (resistive or shorted).
