NCVT3P Dual-Range Non-Contact Voltage Tester with Flashlight

Warnings

[Warning Symbol] 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” LEDs IS 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.

CAUTION: DO NOT attempt to repair this tester. It contains no serviceable parts.

DO NOT expose tester to extremes in temperature or high humidity.

Operating Instructions

Selecting Voltage Testing Mode

The NCVT3P can detect voltage in two distinct modes:

• Mode 1: Detects 70 to 1000V AC.
• Mode 2: Detects 12 to 1000V AC (for lower voltage and higher sensitivity).

With the tester powered ON, successive presses of the NCV Power-ON button (1) will switch between modes 1 and 2. The Power-ON indicator LEDs (3) will show the active mode. The tester powers on in the last used mode.

Checking for the Presence of AC Voltage

1. Press the NCV Power On/Off button (1). After a self-test, a green light will illuminate the tip if no voltage is detected.
2. Before use, test on a known live circuit to verify tester functionality.
3. Place the tip of the tester (5) near an AC voltage source. If voltage is present, the unit will emit audible beeps and the LEDs in the tip (4) will illuminate.

Note: In Mode 2, the tester is more sensitive to high voltage sources and electrically noisy environments. It is recommended to use 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). The flashlight functionality will be disabled to conserve battery for voltage detection.

1. Unscrew the battery cap (9) and remove/recycle spent batteries.
2. Install two new AAA batteries, noting proper polarity.
3. Screw battery cap tightly to ensure a tight seal with the O-Ring (8).

Cleaning

Ensure the tester is turned OFF. Wipe with a clean, dry, lint-free cloth. Do not use abrasive cleaners or solvents.

Storage

Remove batteries when not in use for a prolonged period. Do not expose to high temperatures or humidity. After storage in extreme conditions, allow the tester to return to normal operating conditions before use.
