GENERAL SPECIFICATIONS
The Klein Tools NCVT-6 is a full-range non-contact voltage tester
with an integrated laser distance meter. It can detect voltage from
12V to 1000V AC and can measure distance from 2 in. to 65.6 ft.
(51 mm to 20 m). Under normal operating conditions, at distances
from 51 mm (2 in) – 10 m (32.8 ft) the NCVT-6 has an accuracy
of +/- 1.6 mm (1/16 in). At distances >10m (32.8 ft) – 20m (65.6
ft ) the NCVT-6 has an accuracy of +/- 3.2 mm (1/8 in). The laser
distance meter functions independently from the NCVT.
• Distance Measurement Range: 2 in. to 65.6 ft. (51 mm to 20 m)

• Batteries: 2x AAA 1.5V Alkaline
• Operating and Storage Altitude: Up to 6562 ft. (2000 m)
• Operating and Storage Temp: 32° to 122°F (0° to 50°C)
• Relative Humidity: <85% non-condensing
• Dimensions: 6.45" x 1.32" x 1.21" (164 x 34 x 31 mm)

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 II 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 red or a steadily illuminated red NCV Indicator
indicates the presence of voltage. A steadily illuminated blue NCV Indicator
indicates that no voltage is detected, however 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:
