[0002] At present, with the improvement of automation and integration of electrical equipment, the use of various electronic circuits is very large. When the circuit equipment fails, it is extremely difficult to diagnose and judge the fault point. In view of this situation, a variety of professional electronic circuit equipment fault diagnosis circuits have been developed to deal with the detection and diagnosis of electronic circuit equipment faults. But in use, it is found that the currently used electronic circuit equipment fault diagnosis circuit can only detect and diagnose faults of single or similar types or faults of electronic circuits, but in the process of diagnosis, the operation is relatively complicated , the detection efficiency is low and the accuracy of the detection results is relatively poor, so it cannot effectively meet the requirements of the current electronic circuit types and fault types that need to be detected, thus causing great inconvenience to the fault detection of electronic circuit equipment. There are also some detection devices with various functions, but these devices are often bulky, costly to use, and relatively poor in portability and performance, so they still cannot meet the needs of actual use. In view of this situation, it is urgent to develop a structure Simple, easy-to-use and low-cost invented electronic circuit detection circuit structure to meet the needs of practical use
