ABSTRACT:
An anti-tamper device in an automotive vehicle test system monitors an access panel to the automotive vehicle test system. An alarm is actuated if the access panel is opened. The automotive vehicle test system tests automotive vehicles and prints certificates which verify test results. The access panel is unlocked following the completion of an automotive vehicle test so that an operator can gain access to a printer to retrieve a printed certificate. The test system monitors the condition of the access panel even if power is removed from the automotive vehicle test system. A large capacitor provides power to monitoring circuitry. A data latch, powered by the capacitor, latches the condition of the access panel. The alarm is sounded when power is returned to the automotive vehicle test system and the condition of the latch indicates that an access panel has been opened.
