CHANCE® Truck Boom Leakage-Current Monitor

For continuous performance, this unit mounts on truck body and hardwires into truck’s 12-Volt system, which eliminates battery changeout.

To alert utility-line workers of overcurrent conditions on truck booms, this monitor 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.
