This tool is not intended for continuous contact applications. Contact with
energized conductor should be limited to the amount of time required to note
indication.
To determine the approximate phase-to-phase voltage:
1. Check battery and circuitry for proper operation by pressing and releasing the
power switch. Verify full unit function by contacting with a known energized
high voltage source or with the appropriate Voltage Indicator Tester (C403-
3409 for C403-3374 ARVI and C403-3431 Voltage Indicator Tester for C403-
3375 ARVI).
2. Thread the hook probe into the end fitting of the ARVI and attach universal
fitting to an insulated hot stick of proper length for system voltage involved.
Always use appropriate length stick even if wearing rubber gloves.
Contact with universal ferrule or other part even with rubber gloves will cause
erroneous voltage indication.
Always use with a universal pole to maintain its calibration.

Keep instrument clean and dry.
Do not allow universal fitting to become grounded or contact another phase as this
will cause erroneous voltage indication and could cause severe personal injury or
damage to equipment.
Always maintain proper working clearance between operator and all energized parts
of the ARVI by using proper length universal pole. Failure to follow these warnings
could result in personal injury or damage to equipment.
