DIODE TEST
WARNING:
To avoid electric shock, do not test any
diode that has voltage on it.
1. Set the function switch to the
position.
2. Insert the black test lead plug into the COM socket
and the red test lead plug into the
socket
.
3.
Press the MODE button until “
” appears in the
display.
4.
Touch the test probe tips to the diode or semiconductor
junction you wish to test. Note the meter reading.
5. Reverse the probe polarity by switching probe
position. Note this reading.
6. The diode or junction can be evaluated as follows:
A. If one reading shows a value and the other
reading shows OL, the diode is good.
B. If both readings show OL, the device is open.
C. If both readings are very small or zero, the
device is shorted.
NOTE:
The value indicated in the display during the
diode check is the forward voltage.
