Lite-Check’s Pro-Check 720 and 720AC test instruments for trailer lights and electrical systems allow users to perform a U.S. Department of Transportation-style electrical inspection in only a few moments to identify and monitor electrical faults. The devices, available in both 12V DC battery and 120V AC-powered versions, can be operated by using the front control panel or the included full-function remote control.
The Pro-Check 720, designed for 12V DC trailers using a commercial-style 7-way connector, identifies electrical faults by displaying the conditions on a digital display and sounding alarms unique to each type of fault.
