3. Plug the red test lead into the
V•W• •mA•mA•
jack
and the black lead into the
COM
jack.
4. Remove power from the circuit under test and dis-
charge all capacitors.
5. Connect the probes to the semiconductor device you
want to check and note the meter reading.
6. Reverse the probes and note the second reading.
7. Judge the semiconductor device as follows:
If one reading shows some value and the other is
OL.
, the device is good.
If both values are
OL.
, the device is open.
If both values are very small or zero, the device is
shorted.
Note:
The value indicated on the display during the diode
check is the forward voltage.
