NCV1

INSTRUCTION MANUAL

Introduction

The NCV1 is a convenient pocket-size multifunction tester, which
combines latest digital technology with advanced powerful intelligent
sensor enable it to distinguish high/low AC voltage.

Features include

• Non-contact AC voltage test: from 70-600 V AC
(with auto hi/low sensitive indication)

• DC voltage/polarity check: 1.5 V - 36 V DC

• Continuity check: 0 - 80 M

• Flash light

Safety Notes

• The tester should not be used to test voltages above the stated
rated voltage.

• Operating temperature within -10˚ to +50˚C (14˚ to 122˚F)
and the frequency range from 50 to 500 Hz. Best environmental
temperature range up to 30˚C, humidity 80% at altitude up to
2,000 meter.

• The tester must be tested on a known voltage source to make sure
it is operating properly.

• The tester must not be used in the presence of moisture,
(e.g. dew or rain).

• Damaged tester must not be used.

• Static electricity may be generated by rubbing the "BODY" of
the tester (when pressing the switch) thus causing LED blinks, this
is NORMAL.

• The flashlight always lights up when pressing the switch, this
is NORMAL.

• In case of doubt, please consult a qualified technician.

Self-Test Function

Prior to use, it is necessary to perform a self-test to ensure guaranteed
indication. Press the switch down and touch the "TEST PIN" by other
free hand.

Both LED lights up and buzzer sounds indicating "NORMAL
FUNCTIONING".

Non-Contact AC Voltage Testing

Press the switch when testing.

Identifying polarity of AC voltage of the wire

To locate "LIVE/HOT" side of the wire, hold/grip the wire with your
free hand and gently "TRACE" inward.

Broken wire/fault finding
"FAULT/BREAK" point in the "LIVE/HOT" wire is indicated by an

interruption in sound and light (LED(2)).

Proper connection check

Move the tester close to the hair dryer with the power OFF. The buzzer
comes ON when the plug is inserted improperly, or if the "LIVE/HOT"
wire is improperly connected to the plug.

Ground/Earthing check

Move the tester close to the fan, toaster, electric kettle, dryer
machine, microwave oven, etc.. The buzzer comes ON if the
"GROUND/EARTHING" is not connected in the wiring.
