Auto Range Voltage Indicator

Item Number: C403-3374 Category Search Terms , Brand:

600V – 69kV. This smart new-generation instrument makes hot-line voltage testing easier than ever. Its state-of-the-art electronics eliminate the need for a selector switch. Its automatic ranging function quickly displays the approximate line-to line voltage class.

It provides an easy, yet reliable means for the operator to determine if a line is:

  • a) De-energized or
  • b) Carrying less than normal system voltage from any source or induced charged from an adjacent live circuit energized at full system voltage.


Simple to operate, the tester attaches to an Epoxiglas® insulating universal handle of appropriate length to maintain proper OSHA working clearances.

A single pushbutton activates the instrument, then a single light indicates either Power On (by glowing solid) or Low Battery (by blinking). With a good battery condition, the instrument performs a confirming self-test by illuminating each of the six indicator lights in series while emitting an alternating audible signal. Then the probe can be brought into contact with the conductor. It automatically begins detecting at approximately 480 Volts and holds the display of one of these voltage classes: 600V, 4kV, 15kV, 25kV, 35kV or 69kV phase-to-phase. The audible signal begins as a slow beeping that becomes faster as the final reading is displayed.

  • When not in use, the unit’s energy-saving Sleep mode automatically conserves the battery.
  • For overhead testing, a Shepherd Hook probe is included with the ARVI (Auto-Ranging Voltage Indicator).
  • For underground testing, order as a separate item Bushing Adapter T403-0857.
  • It simply threads onto the ARVI in the field to check for voltage at switch bushings and on cables, using a feed-thru device.
