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.

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.
