5.11. Diode test
Warning:
To avoid electric shock, do not test any diode that has voltage on it.
1. Set the function switch to " Ω /
2. Press the "FUNC" button until the "
display.
3. Insert the black test lead banana plug into the negative COM
jack and the red test lead banana plug into the positive V/
jack.
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 are OL, the device is open.
C: If both readings are very small or 0, the device is shorted.
Note: The value indicated in the display during the diode check is the
forward voltage.
