GENERAL SPECIFICATIONS

The Dual-Range High-Voltage Non-Contact Tester (HVNCVT1) checks for the

presence of AC voltage without making any disconnection in cables, wall sockets,

fuses, circuit breakers, junction boxes, etc. No current flow is needed for correct

operation. The tester warns against dangerous voltage from low to high voltage

applications up to 132kV without contacting the energized conductor. The low-

range setting should be used for detecting 50V AC to 1.5kV AC. It may be used as

a hand-held device ONLY when checking for low voltage. The high-range setting

should be used for detecting 1.5kV AC to 132kV AC. It should ONLY be used with a

hot stick when checking for high voltage.

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.

WARNINGS

To ensure safe operation and service of the tester, follow these instructions.

Failure to observe these warnings can result in severe injury or death.

• Use extreme caution when testing live electrical circuits due to risk of injury from

electrical shock.

• When testing for high voltage, always use hot sticks and rubber gloves meeting

industry standards.

• Follow approved work safety practices and clearances per OSHA Sub-parts

R & V and your company work rules.

• Always test on a known live circuit to verify tester functionality prior to use.

• Do not exceed the limits marked on the instrument itself. Never test voltage

more than 132kV AC RMS.

• Never ground yourself when taking measurements. Do not touch exposed

circuit elements.

• Observe the proper safety precautions when working with voltage above 30V AC

RMS to avoid electrical shock hazard.

• Do not assume equipment or conductors are, or will remain, de-energized.

Always install proper grounding devices before starting procedure.

• Do not operate tester in an explosive atmosphere.

• Do not expose tester to rain or moisture. This increases the risk of fire

or electric shock.

• Do not rely on this tester for shielded wire or cable with concentric neutrals.

• Do not let the unit make contact with live line voltage. Do not touch any exposed

wiring, connections or other energized parts of an electrical circuit.

• 3-phase feeder cables with conductors close to each other may self-cancel the

electric field and not be detected by the device. Verify that the phase conductors

are separated by at least 15" (381 mm) before testing for AC voltage.

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.

MODES OF OPERATION

The HVNCVT1 can operate in two ranges. In low-range mode, the red LED

below the

low-range button

will illuminate.

In high-range mode, the red LED

below the

high-range button

will illuminate.

See

FEATURE DETAILS

for locations of red LEDs.

ON/OFF BUTTON

Press the on/off button

to turn the unit on or off. When the unit is turned on, the

two blue LEDs

will flash and the unit will emit a high-pitched beep sound. See

FEATURE DETAILS

for locations of blue LEDs.

"TEST" BUTTON

Press and hold the TEST button

to perform a self-test on the unit. Look for a

steady blue LED light

and listen for a steady beep sound. This self-test function

ONLY confirms battery sufficiency, system integrity, and operation/active mode.

Always test on known live circuit to verify tester functionality prior to use.

If the two

blue LEDs do not glow and the beep sound is not present, replace battery.

LOW-RANGE BUTTON

When the unit is turned on, press the low-range button

to switch the unit to the low-

range setting. Look for a steady red LED

below the low-range button. Also look for

the two blue LEDs

to blink and listen for a beep sound.

The Low range is 50V AC to 1.5kV AC.

Place the probe tip of the tester

near a low voltage source, but not touching it. Look

for the blue LEDs

o blink quickly and listen for a quickened beep sound when

voltage is present. As the probe tip gets closer to the voltage source, the blue LEDs

and beep sound will be constant. 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.

HIGH-RANGE BUTTON

Before using the unit in High range, 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.

When the unit is turned on, press the high-range button

to switch the unit to the high-

range setting. Look for a steady red LED

below the high-range button. Also look for

the two blue LEDs

to blink and listen for a beep sound.

The High range is 1.5kV AC to 132kV AC.

Place the probe tip of the tester

near a high voltage source, but not touching it.

Look for the blue LEDs

to blink quickly and listen for a quickened beep sound

when voltage is present. As the probe tip gets closer to the voltage source, the blue

LEDs and beep sound will be constant. 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.

FINDING FAULTS IN CABLE

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

button for low-range

or high-range

according to the voltage of the energized

cable being detected. Move the tester along (but not touching) the cable, listening for the

rapid beeping or steady sound and looking for the rapid blinking or steady light from the

blue 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.

For single-phase systems, use voltage-to-ground.

OPERATING INSTRUCTIONS

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 below.

One of the 3 basic methods is used to determine an HRC for a job task.

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

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.

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.
