Full Range ARVI Operating Instructions
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.
