Diode Measurements
1.
Insert the black test lead into the
COM
input jack and the red test lead
into the
Positive
input jacks.
2.
Turn the function switch to “ ” position.
3.
Use the
MODE
Button to select the diode function if necessary (Diode
symbol will appear on the LCD when in Diode test mode)
4.
Touch the test probe tips to the diode or semiconductor junction under
test. Note the meter reading.
5.
Reverse the test lead polarity by reversing the red and black leads, Note
this reading.
6.
The diode or junction can be evaluated as follows:
If one reading displays a value (Typically 0.400V to 0.900V) and the
other reading displays “
OL
”, the diode is good.
If both readings display “
OL
” the device is open.
If both readings are very small or ‘
0
’, the device is shorted.
Non-Contact Voltage (NCV) Measurements
WARNING: Risk of Electrocution, always test the Voltage Detector on a
known live circuit to verify proper operation before use.
1.
Touch the probe tip to the hot conductor or insert into the hot side of the
electrical outlet.
2.
If AC voltage is present, the detector light will illuminate.
Note:
The conductors in electrical cord sets are often twisted. For best results,
rub the probe tip along a length of the cord to assure placing the tip in close
proximity to the live conductor.
Note:
The detector is designed with high sensitivity. Static electricity or other
sources of energy may randomly trip the sensor. This is normal operation.
