Function Overview
The CHANCE® Auto-Ranging Voltage Indicator® (ARVI), model number C4033374, is a smart new-generation instrument that 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.
- Complies with OSHA 1910.269 to Test for Absence of Nominal Voltage
- 600 V to 69 kV For Overhead & Underground
- Bright display lights indicate voltage class
It provides an easy, yet reliable means for the operator to determine if a line is:
- De-energized
- Carrying less than normal system voltage from any source or induced charge 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 push-button 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.
The probe can then 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.
Overhead and Underground Capabilities
For overhead testing, a Shepherd Hook probe is included with the Basic ARVI (Auto-Ranging Voltage Indicator).
For underground testing, Elbow Adapter T4030856 and Bushing Adapter T4030857 are included in the ARVI Kit. They simply thread onto the ARVI in the field to check for voltage at switch bushings or elbows on cables, using a feed-thru device.
