FUNCTION BUTTONS (FIG. 1)
NCV POWER ON/OFF BUTTON
1
To activate the Non-Contact Voltage Testing feature, press and
release the NCV Power-ON button
. The tester will emit a
1
single beep and one of the Power ON LED's
3
indicating which NCVT mode is active (see OPERATING
3
INSTRUCTIONS). To power-OFF the tester, press and hold the
NCV button.
NOTE: The tester will automatically power-OFF following 4 minutes
of inactivity to conserve battery life.
LASER ON/OFF BUTTON
2
Press and hold the Laser Power Button
to activate the laser

pointer. Release the button to deactivate the laser.
WARNING: LASER RADIATION. DO NOT do any of the
following, as severe and permanent eye damage could result:
• DO NOT direct laser beam into eyes.
• DO NOT stare into the beam.
• DO NOT view directly with optical instruments.
To ensure safe operation and service of the tester, follow these
instructions. Failure to observe these warnings can result in severe
injury or death.
• LASER RADIATION, Class IIIa laser. DO NOT direct laser beam into eyes, DO NOT
stare into the beam, or DO NOT view directly with optical instruments as this can cause
severe and permanent eye damage.
• 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.
• 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. 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).
• 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.
• 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
NCVT5 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
the tester between modes 1 and 2. The Power-ON indicator LED's
will indicate the currently active mode. The tester will power-ON in the
mode that was most recently used.
WARNINGS
CHECKING FOR THE PRESENCE OF AC VOLTAGE
1. Prior to use, test on a known live circuit to verify tester
functionality.
2. Place tip of the tester
the unit will emit audible beeps and the LEDs in the tip
illuminate:
Mode
Mode 1
70 – 1000V
Range
Mode 2
12 – 1000V
Range
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
manner each time silent operation is desired.
BATTERY REPLACEMENT
If activating the laser pointer results in a blinking red LED
level is too low to operate the laser, but the NCVT may still be used. If
attempts to use either the NCVT or the Laser Pointer results in a blinking
blue LED
1. Unscrew the battery cap
2. Install two new AAA batteries. Note proper polarity.
3. Screw battery cap tightly to ensure a tight seal with the O-Ring
Be sure tester is turned off and wipe with a clean, dry lint-free
cloth. Do not use abrasive cleaners or solvents.
Remove the batteries when not in use for a prolonged period
of time. Do not expose to high temperatures or humidity. After
