To alert utility-line workers of overcurrent conditions on such aerial devices as insulated ladders and truck booms, the CHANCE® Sentinel sounds an alarm if leakage current reaches a pre-set level. The leakage setting adjusts from 1 to 1,000 microamperes in resolution increments of 0.1 microamp.
The audible warning eliminates the need to watch the actual current level, continuously displayed on the CHANCE® Sentinel’s digital LCD screen. The alarm sounds immediately upon overcurrent and continues until the condition is corrected.
To also trigger a truck horn or other external alarm, a jack on the instrument panel accepts a standard 1/4″ two-conductor phone plug.
A test terminal on the panel permits a simple continuity check of the monitor leads prior to each operation. Before each use, the instrument automatically performs a rapid electronic self test. Simple operating steps are printed on the inside lid panel. A detailed instruction sheet also comes with each unit.
Kit includes 1 coaxial cable and battery, plus 2 jumpers and 3 hose clamps for connections to two- or three-rail ladders. Brackets on box secure to an earth-grounded structure up to 5/8″ thick such as a transmission tower.
