OPERATING INSTRUCTIONS
CHECKING FOR THE PRESENCE OF AC VOLTAGE
1. Press NCV Power On/Off button. After performing a self-test, a green
light will illuminate the tip when no voltage is detected.
2. Prior to use, test on a known live circuit to verify tester functionality.
3. Place tip of the tester
5
near AC voltage. If voltage is present, the unit
will emit audible beeps and the LEDs in the tip
4
will illuminate:
Mode Power-On
LED Color 12 to 70V AC >70 to 1000V AC
Mode 1
70 – 1000V Range
Red
No illumination,
no sound Red LED in tip
4
illuminated, continuous
audible beep
Mode 2
12 – 1000V Range
Blue
Blue LED in tip
4
blinking, pulsing
audible beep
Red LED in tip
4
illuminated, continuous
audible beep
NOTE: In Mode 2, the tester is more sensitive to high voltage sources and
electrically noisy environments. It is recommended to set the tester to
operate in Mode 1 when expected voltages are above 70V AC.
SILENT OPERATION
To activate silent operation, power-ON by pressing and holding the NCV
Power-ON button
1
for more than 2 seconds. Power-ON in this manner
each time silent operation is desired.
CLEANING
Be sure tester is turned off and wipe with a clean, dry lint-free cloth.
Do not use abrasive cleaners or solvents.
STORAGE
Remove the batteries when not in use for a prolonged period of time. Do
not expose to high temperatures or humidity. After a period of storage
in extreme conditions exceeding the limits mentioned in the General
Specifications section, allow the tester to return to normal operating
conditions before using.
DISPOSAL /RECYCLE
Do not place equipment and its accessories in the trash. Items must
be properly disposed of in accordance with local regulations. Please
see www.epa.gov/recycle for additional information.

MAINTENANCE
BATTERY REPLACEMENT
When the battery is low, the unit will power-on with a blinking red
LED
3
; at this point the NCVT-3P will disable the flashlight functionality
to conserve battery function for voltage detection.
1. Unscrew the battery cap
9
and remove/recycle spent batteries.
2. Install two new AAA batteries. Note proper polarity.
3. Screw battery cap tightly to ensure a tight seal with the O-Ring
8
.
WARNINGS
To ensure safe operation and service of the tester, follow these instructions.
Failure to observe these warnings can result in severe injury or death.
• Risk of electric shock and burn. Contact with live circuits could result in death or serious injury.
• Use caution with voltages above 25V AC as a shock hazard may exist.
• A blinking LED or a steadily illuminated LED in the tip and audible beeps indicate presence of voltage. If
no indication, voltage could still be present.
• Before and after each use, verify operation by testing a known working circuit that is within the rating
of this unit.
• Never assume neutral or ground wires are de-energized. Neutrals in multi-wire branch circuits may be
energized when disconnected and must be retested before handling.
• The tester WILL NOT detect voltage if:
• The wire is shielded.
• The operator is not grounded or is otherwise isolated from an effective earth ground.
• The voltage is DC.
• The tester MAY NOT detect voltage if:
• The user is not holding the tester.
• The user is insulated from the tester with a glove or other materials.
• The wire is partially buried or in a grounded metal conduit.
• The tester is at a distance from the voltage source.
• The field created by the voltage source is being blocked, dampened, or otherwise interfered with.
• The frequency of the voltage is not a perfect sine wave between 50 and 500Hz.
• The tester is outside of operating conditions (listed in Specifications section).
• Operation may be affected by differences in socket design and insulation thickness and type; tester may
not be compatible with some types of standard or tamper resistant (TR) electrical outlets.
• In bright light conditions, the LED visual indicators will be less visible.
• When powered-ON, one of the “power-ON” LED’s will be illuminated, and a green light will illuminate
the tip.
DO NOT USE TESTER UNLESS ONE OF THE “POWER-ON” LEDsIS ILLUMINATED.
• Do not use if tester appears damaged or is not operating properly. If in doubt, replace the tester.
• Do not apply more than the rated voltage as marked on the tester (1000V).
• Do not apply to uninsulated hazardous live conductors.
• Detection above 70V AC in Mode 1, or above 12V AC in Mode 2 is specified under "normal" conditions
as detailed below. The tester may detect at a different threshold at different conditions, or may not
detect at all unless:
• The tip of the tester is within 0.25" (6 mm) of an AC voltage source radiating unimpeded.
• The user is holding the body of the tester with his or her bare hand.
• The user is standing on or connected to earth ground.
• The air humidity is nominal (50% relative humidity – non-condensing).
• The tester is held still.
• Always wear approved eye protection.
• Comply with local and national safety requirements.
• If this product is used in a manner not specified by the manufacturer, protection provided by the
product may be affected.
OPERATING INSTRUCTIONS
SELECTING VOLTAGE TESTING MODE
NCVT-3P can detect voltage in two distinct modes, defined by the voltage ranges
to which the tester is sensitive. Mode 1 detects 70 to 1000V AC, Mode 2 detects
12 to 1000V AC.
With the tester powered-ON, successive presses of the NCV
Power-ON button
1
will switch the tester between modes 1 and 2. The Power-ON
indicator LED’s
3
will indicate the currently active mode.
The tester will power-
ON in the mode that was most recently used.
CAUTION
• DO NOT attempt to repair this tester. It contains no serviceable parts.
• DO NOT expose tester to extremes in temperature or high humidity.
