Specifications are subject to change.

FUNCTION BUTTONS

NCV POWER ON/OFF BUTTON 1

To activate the Non-Contact Voltage Testing feature, press and release the NCV Power button 1. All LEDs will illuminate during the self-test, then the tester will emit a single beep, one of the Powers ON LEDs 3 will illuminate 3 indicating which NCVT mode is active (see OPERATING INSTRUCTIONS), and a green light will illuminate in the tip 4. To power off the tester, press and hold the NCV Power button 1. The tester will emit a double beep.

NOTE: The tester will automatically power OFF following 4 minutes of inactivity to conserve battery life.

FLASHLIGHT ON/OFF BUTTON 2
Press the Flashlight Power Button 2 to turn on the flashlight. Press again to turn off the flashlight.
NOTE: The flashlight will automatically power off after 20 minutes to conserve battery life

WARNINGS

To ensure the 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 the presence of voltage. If no indication, the 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 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 the Specifications section).
The operation may be affected by differences in socket design and insulation thickness and type; the 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” LEDs will be illuminated, and a green light will illuminate the tip. DO NOT USE TESTER UNLESS ONE OF THE “POWER-ON” LEDs IS ILLUMINATED.
Do not use if the 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, the protection provided by the product may be affected.

****CAUTION

DO NOT attempt to repair this tester. It contains no serviceable parts.
DO NOT expose the tester to extremes in temperature or high humidity.

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 in the mode that was most recently used.

OPERATING INSTRUCTIONS

CHECKING FOR THE PRESENCE OF AC VOLTAGE

Press NCV Power On/Off button. After performing a self-test, a green light will illuminate the tip when no voltage is detected.
Prior to use, test on a known live circuit to verify tester functionality.
Place the tip of the tester 5 near the AC voltage. If voltage is present, the unit will emit audible beeps and the LEDs in tip 4 will illuminate:

Mode	Power-On LED Color	12 to 70V AC	> 70 to 1000V AC

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.

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.

Unscrew the battery cap 9 and remove/recycle spent batteries.
Install two new AAA batteries. Note proper polarity.
Screw the battery cap tightly to ensure a tight seal with the O-Ring 8.

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.
