INSTRUCTION MANUAL

High-Voltage Contact Tester

5kV to 36kV AC

HVCT1

SYMBOLS

Warning or Caution Risk of Electrical Shock Suitable for Live Working

GENERAL SPECIFICATIONS

The High Voltage Contact Tester (HVCT1) is intended to provide added safety to crew members required to work on

overhead distribution lines. The HVCT1 detects voltage between 5kV AC and 36kV AC. When used properly, the detector

provides visual and audible warning signals of energized conductors.

Always follow approved industry, OSHA and company work practices & safety procedures when working on or near

high-voltage systems.

FEATURE DETAILS

OPERATING INSTRUCTIONS

FOR USE BY TRAINED PERSONNEL ONLY

Anyone using this instrument should be knowledgeable and trained about the risks involved with measuring medium and

high voltage. They must also understand the importance of taking safety precautions as well as testing the instrument

before and after using it to ensure that it is in good working condition.

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.

SITUATIONS TO AVOID

Certain situations and system configurations may cause electrical field interference that could affect the operation of

the tester. It is imperative that the user be aware of and identify all such conditions which may exist. Examples of these

situations include:

1. 90° Corner Configurations – Position the tester to at least 3 ft (1 m) on both sides of corner configurations. Any corner

configuration—including conductor configurations, busbar and other electrical apparatus—may cause field cancellation,

causing the tester to not operate correctly.

2. Same-Phase Interference – When two conductors of the same phase are in close proximity to one another, the field

generated could shield the tester, causing it not to operate. Position the tester in areas which will remove it from these

situations.

3. Opposite Phase Interference – This condition may occur if you’re testing a grounded and de-energized conductor which

is in close proximity to a live, ungrounded conductor. If you are within the field of the energized conductor, this may

cause the tester to indicate that the de-energized line is energized. Attempt to approach the conductor you want to test

from outside this possible field.

SELF-TEST

Before using the tester, perform a self-test of the unit. The HVCT1 uses an integrated electronic device to perform a self-

check of the correct operation of the indicator and power circuits. This self-test function ONLY confirms battery sufficiency,

system integrity, and power is on. Always test on known live circuit to verify tester functionality prior to use, and again

after use in the event of indication that voltage is not present.

Press and hold the Power/Test button

. Look for the red

, green

and orange

LEDs to flash, and listen for a

beep sound.

When the Power/Test button is released, the tester remains on and ready. The green LED will remain illuminated and the

tester remains operative for 2 minutes. When the green LED turns off, the unit is off.

OPERATION

This probe is intended for overhead applications only. See Fig. 1 for ideal detection angle.

Before using the tester, a hot stick or the Klein Tools Telescoping Handle (Cat. No. HV43) must be attached. Only use with

hot sticks and rubber gloves meeting industry standards. Always follow approved industry, OSHA and company work

practices & safety procedures when working on or near high-voltage systems.

The HV43 Telescoping Handle may be used up to 10kV AC.

Check to ensure that the metal probe

is firmly screwed into the top of the

tester before using.

Touch the metal probe directly to the conductor, as close to a 90° orientation as

possible (Fig. 1) Look for the red LED to illuminate and listen for a beep sound,

indicating the presence of voltage. If the red LED does not light and the beep

does not sound, the conductor may not be energized. Perform the Self-Test

again, to ensure the unit is in proper working condition.

Note: in the absence of voltage, the green LED will remain illuminated for up to

two minutes to indicate the tester is still on.

When the orange LED is illuminated, this indicates a low battery. Do not

attempt to use the tester when the orange LED is lit. See Battery Replacement

instructions under MAINTENANCE.
