Abstract

PURPOSE:To improve the accuracy of trouble shooting by separately recognizing places where the number of times of the occurrence of abnormality is above a defined value from places where the number of times is below the defined value and indicating the places above the defined value, while indicating the places below the defined value in the order of the number of times. CONSTITUTION:The detection of abnormality in diagnosed places is carried out by an abnormality detecting means A, and the number of times of the occurrence is counted while storing the number of times and the places of the occurrence by an operating/storing means B. And, a first recognition means C recognizes the places where the number of times of the occurrence of abnormality is above a defined value and forms an indicating information, while a second recognition means D recognizes the places where the number of times of the occurrence of abnormality is below the defined value and forms an indicating information arrangingly in the order from the large number of times. By request for trouble shooting, a selecting means E selects and drives the first and second recognition means C, D in an alternative way, indicating information on an indicating means F. By this structure, it can be prevented to diagnose mounting/removing at the time of inspection, etc., as failure, thereby improving accuracy.
