WARNINGS:
• It is important that users of this tester read, understand, and follow all warnings, cautions, safety
information, and instructions in this manual before operating or servicing this tester. Failure to
follow instructions could result in death or serious injury.
• Risk of electric shock and burn. Contact with live circuits could result in death or serious injury.
• Use caution with voltages above 30V AC as a shock hazard may exist.
• A single blinking LED or a steady glowing LED and an audible beep indicate voltage present. 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 operation conditions (listed in Specifications section).
• Operation may be affected by differences in socket design and insulation thickness and type.
• In bright light conditions, the LED visual indicators will be less visible.
• Do not use if "power on" LED is not 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).
• Detection above 12V is specified under "normal" conditions as specified 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" 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 the product to extremes in temperature or high humidity.

OPERATING INSTRUCTIONS:
Modes of Operation:
• The NCVT-3 can operate as a 12 - 1000V AC non-contact voltage tester and/or a flashlight.
• The proximity sensor indicates voltage strength with an LED scale (Fig. 2).
Turn NVCT Functionality On:
• Press and release the “NCV” power button.
• Listen for single-beep sound and watch for the blue PWR LED to illuminate and remain lit
indicating the unit is powered on.
• Simultaneously, the Bar Graph LEDs (2 yellow and 3 red) will illuminate for approximately
1 second.
• After 1 second, the LED Bar Graph will turn off, then display the battery level:
°
All 5 LEDs lit indicate a full battery
°
1 LED lit indicates batteries are at approximately 20% of capacity
Turn NVCT Functionality Off:
• Press and release the “NCV” power button.
• Listen for double-beep sound and watch blue LED turn off.
Checking for the Presence of AC Voltage:
• Prior to use, test on known live circuit to verify tester functionality.
• Place tip of tester near AC voltage. If voltage is sensed, the unit will emit audible beeps
and the proximity sensor will indicate strength of voltage detected (Fig. 2).
NCVT Auto Power Off:
• After 4 minutes of non-use, the NCVT tester automatically powers off to conserve battery life.
• Measuring a voltage will reset the 4 minute timer.
• Upon power off, the unit will emit a double-beep sound and the blue LED will turn off.
NOTE: This feature is disabled when flashlight is on. When flashlight is turned off, the NCVT
four minute timer will begin.
Turn Flashlight On/Off:
• Press and release “Flashlight” button to turn flashlight on or off.
Flashlight Auto Power Off:
• After 20 minutes on, the flashlight will automatically power off. This will save batteries if the
flashlight is accidently turned on or left powered on.
• Before automatically powering off, the unit will “chirp” for 10 seconds.
• Pressing the flashlight button while chirping will reset the 20 minute timer, and keep
the flashlight on.
• If no button is pressed, the flashlight will turn off.
Low Battery Indication:
• When the battery drops to approximately 20% of capacity, the NCVT-3 will disable the
flashlight functionality. This will conserve the battery, and allow the unit to function as a
voltage detector for several more hours.
• When the flashlight is on and the battery drops to approximately 20% of capacity, the unit will
“chirp” 4 times, and then disable the flashlight.
• The NCVT function will remain on, and will not be affected.
BATTERY REPLACEMENT (Fig. 1):
• Unscrew cap and remove from body.
• Replace the 2 AAA 1.5V batteries – observe proper polarity.
• Screw cap on body until cap is fully seated.
• Damage to O-ring on cap seal can affect IP67 rating but will not affect operation.
CLEANING:
Turn instrument off. Clean the instrument by using a damp cloth. Do not use abrasive cleaners or solvents.
STORAGE:
Remove the batteries when instrument is 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 Specifications section, allow the instrument to return to normal operating conditions before using it.
DISPOSAL / RECYCLE:
This symbol indicates that equipment and its accessories shall be subject to
a separate collection and correct disposal. Do not place equipment and its
accessories in the trash. Items must be properly disposed of in accordance with
local regulations.
