SAFETY INFORMATION
 Warning

To prevent possible electrical shock, fire, or
personal injury:

• If the Tester is used in a manner not specified
by the manufacturer, protection provided by
the Tester may be affected.

• Test on a known live source within the rated
AC voltage range of the product both before
and after use to ensure the Tester is in good
working condition.

• When using the Tester, voltage may be
present even if the tip does not glow. The
Tester indicates active voltage in the presence
of electrostatic fields of sufficient strength
generated from the source voltage. If the field
strength is low, the Tester may not provide
indication of live voltage. Lack of an indication
occurs if the Tester is unable to sense the
presence of voltage which may be influenced
by several factors including, but not limited to:

- Position of the earth conductors in the
environment under test

- Shielded wire/cables

- Thickness and type of insulation

- Distance from the voltage source

- Fully-isolated users that prevent an
effective ground

- Receptacles in recessed sockets / differences
in socket design

- Condition of the Tester and batteries

• The Tester is not the appropriate tool to check
for the absence of voltage. Use a voltage
tester therefore.

• Do not use the Tester if it appears damaged or
is not operating properly. Closely examine the
probe tip for cracks or breakage before use. If
in doubt, have the Tester serviced.

• Do not apply more than the rated voltage as
marked on the Tester.

• When operating the Tester, keep fingers
behind the finger guard.

• Do not use the Tester if it is not flashing upon
power on.

• Use caution with voltages above 30 V AC as a
shock hazard may exist.

• Comply with local and national safety requirements.

• Use proper protective equipment as required
by local or national authorities.

APPLICATIONS

• Detects the presence of AC voltage in cables,
circuit breakers, wall sockets, junction boxes,
fuses, extension cords and more.

• Tests voltage through wire insulation.

• Identifies cable breaks in wires, cords and
lighting systems connected in series.

• Identifies polarity (line vs. neutral) of receptacles
and cables. (Depending of the internal
construction and dimension of receptacles in
different countries this application may be
influenced.)

• Tests voltage without contact.

• Safety CAT IV 1000 V rated for a wide range of
applications including industrial, commerical,
and residential.

• Water-resistant IP65 rated for indoor and
outdoor use.

• Magnetic solenoid detection to diagnose
electromagnets and relays (NCV-1040 only).

OPERATING INSTRUCTIONS
Turning the Tester ON

To turn the Tester on, momentarily press the ON/OFF
button. A continual single flash visually indicates the
Tester is active in default voltage range

Press the ON/OFF button again to switch to high
sensitivity range

only).

A continual double flash indicates the Tester’s
sensitivity range is at the 12 to 50 V range.
Note: Please remove the battery insulator before first
time use.

(12 to 50 V for NCV-1030 and NCV-1040

(50 to 1000 V).

Turning the Tester OFF

Press and hold the ON/OFF button for longer
than two second to turn the Tester off. The absence
of flash at the tip indicates the Tester is inactive.

Auto Power Off

To save battery life, the NCV-1030 and NCV-1040
are enabled with an automatic power off feature.
The Tester will automatically power off after

approximately 3 minutes of non-use.

Checking for the Presence of AC Voltage

To test for the presence of AC voltage in a
receptacle, insert the tip of the Tester. To test a
wire, approach the wire with the tip of the Tester.
Switch between default (50 V to 1000 V AC) and
high sensitivity (12 V to 50 V AC) voltage range
detection by short pressing the ON/OFF button
(NCV-1030 and 1040 only). The LED at the tip of the
Tester will illuminate solid bright red and a buzzer
will sound when AC voltage is detected. Note: High
sensitivity range is optimized for 12 to 50 V range
with a maximum indication up to 1000 V. Using
the tester above 50 V in high sensitivity range may
affect polarity indication.

When operating the Tester, keep fingers behind
the finger guard.

Checking for the Magnetic Field (NCV-1040)

The NCV-1040 can test for a magnetic field in
addition to AC voltage detection. A solid yellow
LED will illuminate when a magnetic field is
detected.

Note: If AC voltage and a magnetic field are
detected simultaneously, the Tester will flash both

red and yellow.

BATTERY REPLACEMENT & CARE
Low Battery Indication

The NCV-1030 and NCV-1040 Testers provide a low
battery indication in the form of a slowly blinking
red LED upon power on when battery level is low
and the batteries should be replaced. At that point
no voltage indication is possible.

The NCV-1020 does not provide the same
indication; instead, batteries will need to be
replaced when no LED appears upon power on.

Battery Replacement

To remove the battery cap, use the thumb grip to
pull it upwards and outwards. Remove batteries
and replace with (2) AAA 1.5 V alkaline batteries,
noting the battery orientation as shown on the
side of the tester. Replace the cap.

If the Tester will not be used for a long period
of time, remove the batteries.

Cleaning

The Tester can be cleaned with a mild solution of
soapy water. Apply sparingly with a soft cloth and
allow to dry completely before using. Do not use
aromatic hydrocarbons, gasoline, or chlorinated
solvents for cleaning.
