GENERAL SPECIFICATIONS

The Broad-Range High-Voltage Non-Contact Tester (HVNCVT2) is an instrument
for verifying the live or de-energized status of conductors and other exposed
electrical equipment. The tester warns against dangerous voltage in several different
ranges without contacting the energized conductor. Only use with hot sticks and
rubber gloves meeting industry standards. Verify the rotary switch setting before
measuring voltage, to ensure it is on the correct setting for your application.

Always follow approved work safety practices and clearances per OSHA Sub-parts
R & V and all company work rules. For Minimum Approach Distances (MAD), see
OSHA Tables R-6 and R-7 (pages 8 & 9) in this manual.

OPERATING INSTRUCTIONS

Prior to use, always inspect the tester for visible signs of damage. If there is
any sign of damage, or if the tester does not operate correctly, discontinue use.

Always test on a known live circuit to verify tester functionality. The tester should be used
as an indication only.

Tester should be kept clean and dry. If it is not, wipe with a clean, dry lint-free cloth.

TEST FUNCTION

Turn the sensitivity selector knob 5
unit. Look for a steady red light from all 3 LEDs

to TEST in order to perform a self-test on the

and listen for a steady high-pitched

1

sound. This self-test function confirms battery sufficiency, system integrity, and
operation/active mode. Always test on known live circuit to verify tester functionality
prior to use.

If the 3 red LEDs do not glow and the beep sound is not present, replace

batteries.

240V AC (Secondary Test)

Perform a second test function prior to use by turning the sensitivity selector knob

5

to 240V and placing the dome near a low voltage live conductor. If a low voltage live
conductor is not available, rub the dome against an item of clothing to generate static.
Look for a blinking red light from all 3 LEDs

and listen for a beeping sound. See

1

Fig. 1 on page 5 for ideal detection angle. Always test on known live circuit to verify
tester functionality prior to use.

If the 3 red LEDs do not glow and the beep sound is

not present, replace batteries.

OPERATION

Before using the unit, a hot stick must be attached. Only use with hot sticks and rubber
gloves meeting industry standards. Always follow approved work safety practices and
clearances per OSHA Sub-parts R & V and all company work rules.

Turn the sensitivity selector knob 5 to the appropriate setting. It is recommended to
start with a lower test setting than the actual working voltage, then gradually increase
the setting until the voltage is detected.

Gradually move the tester towards the live conductor until the warning signal is triggered.
See Fig. 1 on page 5 for ideal detection angle. Always maintain the minimum approach
distances listed in OSHA Tables R-6 and R-7 on pages 8 & 9 in this manual.

OPERATING INSTRUCTIONS

FINDING FAULTS IN CABLE

The tester may be used for finding faults in some flexible cables. Turn the

5

sensitivity selector knob

to the appropriate setting for the energized cable
being detected. Move the detector along (but not touching) the cable, listening for
rapid beeping or steady sound and looking for the rapidly blinking or steady red

1

light from all 3 LEDs

. When the fault is reached, the unit will no longer beep
or blink. See Fig. 2 on page 5. Always maintain the minimum approach distances
listed in OSHA Tables R-6 and R-7 on pages 8 & 9 in this manual.

Employers may use the minimum approach distances in this table provided the worksite is
at an elevation of 3,000 feet (900 meters) or less. If employees will be working at elevations
greater than 3,000 feet (900 meters) above mean sea level, the employer shall determine
minimum approach distances by multiplying the distances in this table by the correction factor
in OSHA's Table R-5 Altitude Correction Factor, corresponding to the altitude of the work.

Arc rating is defined in article 100 NFPA 70E 2015 Edition.

2

Face shields are to have wrap-around guarding to protect not only the face but also the
forehead, ears and neck, or alternatively, an arc-rated flash suit hood is required to be worn.

3

If rubber insulating gloves with leather protectors are used, additional leather or arc-rated
gloves are not required. The combination of rubber insulating gloves with leather protectors
satisfies the arc flash protection requirement.

MAINTENANCE

BATTERY REPLACEMENT

1. Unscrew the tester handle (battery compartment) from the tester head.

Remove the 3 batteries.

2.

Replace with 3 new batteries (1.5V “C” type). Batteries should be placed in the

3.

handle with the negative (-) end down into the handle first, and the positive (+)
end upwards towards the head.

Screw the handle and head back together, ensuring that the black rubber O-ring

4.

is still in place, taking care not to damage the O-ring.

CLEANING

Be sure tester is turned off and wipe with a clean, dry lint-free cloth.

Do not

use abrasive cleaners or solvents.

STORAGE

If the tester is not to be used for periods of longer than 60 days, remove the
batteries and store separately from the tester.

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 or www.erecycle.org for additional information.
