Full Range ARVI Operating Instructions
Function and Design Overview
The CHANCE® Full-Range Auto-Ranging Voltage Indicator (ARVI), model number PSC4032915, is a
portable tool to confirm that an AC (Alternating Current) high voltage circuit is energized or
de-energized prior to performing maintenance. It provides field practicality over the two points of
contact measurement method. Readings from the Full-Range ARVI represent the class of voltage that
is present on the line.
The Full-Range ARVI is used as a secondary means to confirm the condition of a circuit after
principal work procedures such as visible open gaps, dispatcher hold orders, and apparatus tag-outs
have rendered the circuit de-energized. The unit utilizes a single point of contact to the conductor,
therefore it is not a voltmeter. It is designed to determine approximate Phase-to-Phase nominal
voltage up to 765 kV AC 50/60 Hz.
The Full-Range ARVI is an electric field intensity indicator, which is calibrated to illuminate an LED
(light-emitting diode) representing the class of voltage that is present on the conductor. It responds
to the magnitude of the field gradient between its end probe and a floating electrode. The device
may also indicate the combined field intensity from nearby conductors, including ground wires and
grounded equipment. If the universal coupling is too close to a ground, another phase, or another
voltage source, the voltage indication will tend to be high. If the universal coupling is too close to a
jumper or equipment of the same phase, the indication will tend to be low. The tool must always be
used with an appropriate length Hot Stick for safety and to maintain its calibration.
This device is an AC (alternating current/alternating voltage) only indicator; do not use it to detect
DC (direct current/non-alternating voltage).
NOTICE
Before and after each use, always test the unit on a known energized voltage source or with the
Voltage Indicator Tester to verify proper operation.
! WARNING
Features
• Meets intent of OSHA 1910.269 to test for absence of nominal voltage
• Used to determine if power lines are at rated voltage, have induced voltage, or are de-energized
• Capacitive Test Point through 765 kV AC for overhead and underground systems
• Adjustable audible alarm
• Power-saving sleep mode (auto-off)
• Approximate Phase-to-Phase voltage ranges are indicated by LED lights
• Automatic Hold Mode
• Battery drawer for simple battery replacement
• QR code located in the instructions and on the unit itself
This instrument is not a voltmeter; hence, the manufacturer claims no specific accuracy, and therefore,
no specific accuracy is to be assumed by the user. Readings will vary with the field intensity,
determined by a great variety of field conditions including proximity, size, and orientation of all system
components in the vicinity, both energized and grounded. Erroneous readings may result from being
too near other energized conductors or being too near another phase or ground. To avoid such field
distortions, keep the unit as far away as practical from all system components other than the specific
conductor being tested.

Operations for Overhead
Turn the Unit On:
1. Momentarily depress the “Power Button” for approximately 2 seconds.
a. Upon power-up, each LED will illuminate individually from the lowest voltage to the highest
followed by the adjustable audible alarm. These tests verify the function of the LEDs, alarm,
batteries, and internal circuitry.
b. Following the adjustable audible alarm, the “PWR” LED will continuously flash. The unit is
ready for use.
c. Always install the unit on an appropriate length insulated Hot Stick.
Take a Reading:
2. Install the supplied Shepherd Hook and place the unit in contact with the power line conductor.
Minimum Approach Distances (MAD) should be adhered to at all times.
a. Ensure that the green "PWR" LED is flashing before, during, and after testing.
b. Keep the Full-Range ARVI perpendicular to the phase conductor and away from poles or
structures a distance of at least twice the circuit’s phase spacing. If possible, test away from
structures, jumpers, risers, cutouts, insulators, ground wires, and any system components that
may cause reading errors.
c. The audible alarm will begin to beep as the unit senses the electric field. The Range LED that
corresponds with the system voltage level present on the conductor will begin to blink. The
higher the voltage, the faster the beeping occurs. Audio and visual indications may begin
before contact is made.
d. Test three or four locations to check consistency. Where little or no consistency is apparent,
consider the highest reading as correct.
e. All interpretations should take into account the circuit configuration, length, proximity to
other lines; and should be consistent with previous experience on the same circuit with
this instrument. If ever in doubt about interpreting Full-Range ARVI readings under any
circumstance, always assume circuit is energized and take appropriate safety precautions.
Hold Mode: Refer to page 14.
Turn the Unit Off:
3. To turn the Full-Range ARVI off:
a. Press and hold the "Power Button" on the unit for 3 seconds:
i. The adjustable audible alarm will generate two series of three tones each.
ii. The unit will turn off after the second series of tones.
b. Or the unit will automatically power itself down (auto-off) after approximately 15 minutes of
inactivity.

Operations for Overhead (Cont.)
Both the electromagnetic action of current and electrostatic action of voltage can induce a high
static condition on the de-energized circuit. Activity effects can exist between all conductor pairs.
The Full-Range ARVI indicates the combined field intensity from all other conductors, including
ground wires.

Operations for Underground
Before and after each use, always test the unit on a known energized voltage source or with the
Voltage Indicator Tester to verify proper operation.
! WARNING
Always use appropriate length insulated Hot Stick even when wearing rubber gloves. Contact with
universal coupling or other parts, even when using rubber gloves, will cause erroneous voltage
indication. Also, due to the close proximity of conductive metals, the readings taken in URD
cabinets will typically be higher than on an overhead line.
As with overhead, the same basic rules and procedures apply when using the CHANCE® Full-Range
Auto-Ranging Voltage Indicator (ARVI) on underground systems. Follow these three very important
additional instructions when using the tool on underground equipment:
1. When testing dead-front URD equipment, use an appropriate Bushing Adapter on the Bushing
Well. On Capacitive Test Points, use the Straight Probe. Never use the Shepherd Hook on URD
equipment.
2. Use extreme caution when testing live-front URD equipment. Use applicable safe work
practices and procedures. Do not use any probes or Bushing Adapters on the Full-Range ARVI
when testing live-front URD equipment. Only use a small hex head machine screw (1/4-20 X
3/8" long).
3. When testing live-front URD equipment, the Full-Range ARVI may detect fields from adjacent
conductors, energized parts or grounds, including grounded cabinet components. Indication of
an energized field may not be sufficient to isolate one specific conductor.
! DANGER
Do not allow the universal coupling to touch any part of the URD (Underground Residential
Distribution) cabinet, to become grounded in any other way, or to contact another phase as this
will cause erroneous voltage indication and could cause severe personal injury or damage to
equipment.

Capacitive Test Point
Capacitive Test Points must be free of corrosion and contamination for valid testing.
If ever in doubt about interpreting the CHANCE® Full-Range Auto-Ranging Voltage Indicator
reading under any circumstance, always assume circuit is energized and take appropriate safety
precautions.
! DANGER
Failure to use proper safety equipment, procedures, and work rules could result in personal injury
or damage to equipment.
! WARNING
1. To test Capacitive Test Points on dead-front URD equipment, safely remove the protective cap/
cover from the Elbow by using appropriate work practices and procedures. Follow the Elbow
manufacturer’s recommendations on proper use of all Capacitive Test Points. Capacitive Test
Points must be free of corrosion and contamination for valid testing.
2. While observing all required safe work practices, and with an appropriate length insulated Hot
Stick attached to the Full-Range ARVI’s universal coupling, touch the short Straight Probe of the
unit to the Elbow Test Point. Depending on the condition of the Test Point, either the "Cap. TP" or
one of the Range LEDs should be illuminated.
3. When taking a reading, the area of and around the Capacitive Test Point must be dry and free
of contaminants. The Capacitive Test Point has no direct connection to the conductor. It uses an
impedance capacitance tap and only high impedance indicating instruments designed for this
application should be used. If a reading is indicated, the Cable is energized, but if no reading is
indicated this is not sufficient to establish a de-energized circuit. For safety reasons, use other
approved safe procedures, such as direct contact, to determine if the Cable is de-energized.
