PCR is composed of metal shaft, conductive foam rubber layer, resistance layer, protective layer, responsible for charging the OPC surface. When one to two cycles are used, the PCR is susceptible to aging, resulting in an increase in surface resistance. For the manufacturer, it is important to detect the surface resistance of the PCR. Therefore, it is necessary to design a PCR resistor detection system for batch detection of the advantages and disadvantages of PCR components. The PCR resistance detection system to achieve the following functions: 50V ~ 500V high voltage adjustable generation circuit, current sampling circuit and conditioning, matrix button to achieve, the host computer communication and debugging information display
