6511A12-24V Multi-functional Auto Tester with LCD Display


Test the automotive electrical system within 12-24V. In order to save the testing hours for the automotive electrical system, the tester is designed to test the system without re-connection between the vehicle battery and the testing components. For the testing and safety purpose, the tester contains short-circuit protection, which can also check the ground connection without voltage drop test. The short-circuit protection system contains the recoverable fuse, so the technician will not waste the fuses during the testing. The extension cable is long enough for a technician to test the whole system for the vehicle.
Therefore, the technicians do not have to search for ground connection constantly.
