During the detection, the external power supply is connected to each component, so that the electromagnetic transmitter in the electromagnetic transmitting tube 20 emits electromagnetic waves. At the same time, the strength of the electromagnetic waves emitted by the electromagnetic transmitter is adjusted by the first adjustment knob 13, so that the electromagnetic environment in the detection tube 30 changes, so as to detect the working conditions of the detected device under different electromagnetic intensities. Secondly, the drive motor 321 can be operated by the external power supply, and then the drive motor 321 is adjusted. Driven by this, the placement plate 33 moves along the axis in the second cylinder wall 31, so that the distance between the detected device and the electromagnetic transmitter can be changed, so that the interference of the detected device between different distances can be detected, and the minimum distance of interference can be detected.
