CHANCE® Auto-Ranging Voltage Indicator (600V-765kV)

  • Complies with OSHA 1910.269 to Test for Absence of Nominal Voltage
  • 600V to 765kV For Overhead Conductors
  • Bright display lights indicate voltage class

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, reliable means for the operator to determine if a line is:

  • De-energized
  • 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® 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 100V and holds the display of one of these phase-to-phase voltage classes: 600V, 4kV, 15kV, 25kV, 35kV, 69kV, 115kV, 161kV,230kV, 345kV or 500kV.

The audible signal begins as a slow beeping that becomes faster as the reading is increased.

When not in use, the unit’s energy-saving Sleep mode automatically conserves the battery.
