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