Truck Boom Leakage-Current Monitor

Truck Boom Leakage-Current Monitor: It mounts on truck body and hardwires into truck’s 12-Volt system, eliminating need for battery changes. The alarm sounds immediately upon overcurrent and continues until condition is corrected, eliminating the need to watch the actual current level that is continuously displayed on the digital LCD screen. A jack on the instrument panel accepts a standard ‘A” two-conductor phone plug to also trigger a truck horn or other external alarm. It automatically performs a rapid electronic self test before each use,and a test terminal on the panel permits a simple continuity check of monitor leads prior to each operation
