The operation instruction is issued by the user and can be the increase or decrease of the voltage, resistance and capacitance. Correspondingly, the control instruction is the voltage switching instruction, the resistance switching instruction and the capacitance switching instruction. When the voltage switching instruction is sent, the power voltage adjusting module 102 receives the voltage switching instruction and adjusts the voltage of the power supply; when the resistance switching instruction is sent, the resistance adjusting module 103 receives the resistance switching instruction and adjusts the resistance value; when the capacitance switching instruction is sent, the capacitance adjusting module 104 receives the capacitance switching instruction and adjusts the current capacitance.

The current detection module 107 can also be used for fault diagnosis. When a fault occurs in the circuit, the current value may change. By monitoring the current value, the fault can be discovered in time and appropriate maintenance measures can be taken. The selection and use of the current detection module 107 also need to be determined according to the specific application scene and requirements.

[0032] Further, in order to more intuitively display the values of the current voltage, resistance and capacitance and other information, so that the user can more intuitively obtain the required data or information, the conversion device provided in the embodiment includes an LCD display module 108 connected with the single-chip microcomputer control module 101. The single-chip microcomputer control module 101 sends the data or information to be displayed to the LCD display module 108, and the LCD display module 108 receives and processes the data or information.

This design not only realizes test simplification and data accuracy, but also has good real-time performance, strong anti-interference performance and low distortion characteristics.

[0035] Further, connecting the power voltage adjustment module 102 with the resistance adjustment module 103 can protect the components in the circuit from damage caused by excessive voltage.
