Furthermore, the transmission line of the high-voltage probe is properly extended to be properly far away from the output module 1011 of the high-voltage power supply 101, so that accidents are avoided, and safety can be effectively guaranteed.
As a specific scheme, the display module 103 is electrically connected to the detection module 102, and is configured to display the real-time voltage value acquired by the detection module 102; specifically, the display module 103 includes at least one oscilloscope.

In addition, the MCU module 106 and the D/A module 107 transmit information in a digital signal mode in the transmission process, so that the data is more stable, the anti-interference capability is enhanced, the data is not easy to lose, and the transmission distance of analog signals is effectively shortened and the anti-interference capability is enhanced by using the MCU module 106 and the AD module.
As a preferable scheme, the MCU module 106 and the D/a module 107 are respectively independent from the output module 1011, where "independent" means that the MCU module 106, the D/a module 107 and the output module 1011 maintain relative positions in space that are not interfered with each other, and the distance between the MCU module and the D/a module 107 and the high voltage power supply 101 is moderate, so as to reduce interference of external electrical environment on data transmitted by the MCU module and the D/a module.
