Non-Contact, High Voltage Detector 275HVD 1
Testing the 275HVD Before Operating:
The 275HVD is a battery operated instrument. It must be carefully checked each
time before use.
(1) Test Before Use:
Switch the sensitivity to “TEST”. The warning buzzer should emit A continuous
audible tone and the warning light LEDs should stay lit up with the 275HVD in all
positions. This indicates that the sensor is operational and the battery functional.
If there is any intermittent buzzer and/or light, do not operate the 275HVD.
Further operation is not to take place until authorized and qualied personnel
have reviewed the operation and cleared the instrument after proper Test
and Functional tests.
(2) Detection Test:
After a successful Test (1), perform the following steps to ensure that the 275HVD
detects voltage on a known live conductor.
Select the 240V• AC range and place the sensing head near a known live
(low voltage) conductor (if not available, rub the sensor with a cloth or
against a clothing item to generate a DC static charge which will trigger
the sensor circuit detection).
The warning light and warning beeper should go ON as if a live conductor•
were being tested.
NOTE: Positioning the sensing dome near a computer screen or a TV screen
(not liquid crystal display type) should also trigger the tester while on the 240V
selection.
(3) Battery:
If any malfunction or instability of the light and/or buzzer occurs, then the•
user should also check the battery compartment and/or batteries.
When installing a new set of batteries or before use, tighten the battery•
compartment completely and properly (insure the O-ring is well seated),
select the Test position and move the meter in different positions. In the
Test mode the light and buzzer should remain ON continuously and
be steady at all times. Otherwise, do not use the instrument.
Failure to properly close the battery compartment and/or the use of weak•
batteries may result in intermittent operation. Do not use the 275HVD if
intermittent operation occurs (see Test Before Use).
WARNING! - READ BEFORE USE!

Non-Contact, High Voltage Detector 275HVD 3
CHAPTER 1
INTRODUCTION
Warning
The Model 275HVD Non-Contact High Voltage Detector has been
designed with safety in mind. However, no design can completely protect
against incorrect use. The 275HVD should be used by trained and
qualied personnel only. The 275HVD can only be used with an
insulated rod or “Hot Stick” rated at the appropriate working volt-
age. The 275HVD Non-Contact High Voltage Detector is never to be
put into direct contact with a live conductor.
If caution or poor safety practices are not adhered to, electrical cir-
cuits can be dangerous and lethal.
This instrument should only be used by authorized and properly
trained personnel who fully understand the High Voltage testing
procedures.
Personnel working with high voltages should be trained regularly.
• Read the user manual carefully and completely before using the
tester. Fully understand the instructions before using this product.
• Follow the instructions for every test.
• Take all the necessary safety precautions. Do not exceed the limits
of this instrument.
• The 275HVD Non-Contact High Voltage Detector must never be in
physical contact with any conductor. This is a proximity detector, not
a detector which works by contact.
• Tests must only be carried out with the 275HVD attached to an
approvedinsulatedberglassrodorHotStick.
• Alwaysuseanauthorizedberglass(orequivalent)rodorHotStick
appropriately rated for the voltage with which you are working.
• Always check that the 275HVD Non-Contact High Voltage Detector
is working before and after the test.
• Verify the Range Switch setting before measuring. Make sure it is on
the correct setting for your application.
• Do not touch any exposed wiring, connections, or other “live” parts of
an electrical circuit.

1.1 International Electrical Symbols
This symbol on the instrument indicates a WARNING and that
the operator must refer to the user manual for instructions before
operating the instrument. In this manual, the symbol preceding
instructions indicates that if the instructions are not followed, bodily
injury, installation/sample and product damage may result.
Risk of electric shock. The voltage at the parts marked with this
symbol may be dangerous.
1.2 Receiving Your Shipment
Upon receiving your shipment, make sure that the contents are consistent
with the packing list. Notify your distributor of any missing items. If the
equipmentappearstobedamaged,leaclaimimmediatelywiththecar-
rier and notify your distributor at once, giving a detailed description of any
damage. Save the damaged packing container to substantiate your claim.
Do not use an instrument that appears to be damaged.

CHAPTER 2
PRODUCT FEATURES
IMPORTANT WARNING
Never assume conductors that have been tested as
de-energized will stay de-energized.
Always install proper grounding devices before working.
Failure to do so may result in serious injury or death.
2.1 Description
The Non-Contact High Voltage Detector Model 275HVD is a high voltage
detector by proximity. It is not designed to enter into contact with
conductors.
The 275HVD should never touch conductors and must be used
with an insulated berglass rod or Hot Stick appropriately
rated for the voltage being tested.
The Non-Contact High Voltage Detector Model 275HVD is not a “measuring
instrument” per say, rather it is a product designed to warn the user of the
presence of voltage in a particular work site.
The 275HVD uses an internal sensor designed to detect the radiated
electrical eld (V/m) present in energized conductors. The radiated
electricaleldincreaseswiththelinevoltagebutdecreaseswithdistance
and/or shielding.
The 275HVD has eight voltage range settings. These correspond to
internaleldsensitivitysettings:thelowerthevoltagesetting;thehigher
thesensitivitytodetecttheelectricaleld;and,thegreaterthedetection
distance. It also has an “auto-test” setting to check functionality (see §
4.3).

6 Non-Contact, High Voltage Detector 275HVD
The 275HVD is battery powered and contains three standard 1.5V “C”
cells in the shaft below the sensing head.
Whenanelectricaleldisdetected,asoundannunciator(high-pitch,high
-powered buzzer) and visual indicators (bright LEDs) are triggered ON,
warning the user.
The body is made out of industrial grade UL rated polyamide (Type 66
Nylon).Theshotgunadapterattheshaftendisdesignedtotintomost
Hot Stick adaptors.
2.2 Typical Uses (always use a Hot Stick)
• Identifyandchecklivecables
• Checkanddetectlivehighvoltagecables
• Findfaultinexiblecables
• Checkgroundingequipment
• Serviceneonlighting
• Tracelivewires
• Checkhighfrequencyradiation
• Detectresidualorinducedvoltages
IMPORTANT WARNING
The275HVDdetectsradiatedelectricalelds.Toaccomplishthis,
an energized cable or sample must radiate an electrical eld.
Shielded cables or shielded samples do not radiate, or radiate very
smallelectricalelds.Also,cableswithconcentricneutralswillhave
asmaller/lowerradiatedeldthanplaininsulatedcables.
The 275HVD may not detect, as expected, an electrical eld on
shielded cables (buried cables are often shielded) or shielded
samples and the 275HVD has lower sensitivity on cables with
concentric neutrals.
It is not recommended to use the 275HVD on shielded cables or
shielded samples. Use extreme care on cables with concentric
neutrals (use a low setting).
