Abstract

PURPOSE: To increase the reliability and to simplify the maintenance, by the self- diagnosis for the failure of circuit function, through adding the unit in response to the detection of failure in the check circuit, in an ultrasonic inspector.
CONSTITUTION: The circuits 4 to 8 and the probe 1 of the ultrasonic inspector are individually provided with the check circuits 9 to 15 to check the circuit function, and the overall judgement circuit 16 to stop the inspector in response to the detection of faulure of the circuits 9 to 15 is provided. Further, before the flaw detection work for the failure F of the inspected object W or on its way, the propriety of the circuit function of the probe 1 and the constituting circuits 4 to 8 of the instrument section 2 can individually be judged by feeding the check instruction to the check circuits 9 to 15. Further, if failure is taken place, the circuit 16 stops the operation of the unit and a lamp is illuminated to the check circuit provided with the circuit having failure, allowing to confirm the failed part easily.
