If the polarity of the test leads is reversed
with diode polarity (or forward bias voltage
is above 1V),
OL
appears in the LCD. This
allows you to distinguish the anode and
cathode sides of the diode.
3.8. Non-Contact Voltage Detection
(NCV)
NCV can only detect live AC voltage
referenced to the ground. Under some
conditions, NCV may not detect live
voltage present in electrical circuits or
equipment. To ensure safety, never
touch the circuit under test even if NCV
does not detect voltage.
1.
Turn the rotary switch to
NCV
.
2.
Point the top of the instrument (labeled
NCV) towards the conductor to be
tested, and approach the conductor
with the instrument.
3.
If AC voltage is detected, the LCD
backlight blinks red.
NCV can detect voltages of 100V and
higher.
