Abstract

PURPOSE:To detect a malfunction of detecting operation caused by the high speed running of a vehicle and the response speed of a detector by altering a change-of-frequency time by means of a time element controller for a resonance circuit, and to proved a testing device which is also applied to a detector using a device for preventing incorrect information from being received.
