| 摘 要： | 为了实现自动测量电阻的目的,自动电阻测试仪以C8051F020单片机为核心,在被测电阻上通过已知的恒定电流,取出被测电阻上的压降,送入单片机A/D转换的输入端,经单片机处理,由LCD12864系统直接显示电阻值。通过控制继电器切换档位,具有自动电阻筛选功能,满足了测试对象的多变性,提高了测量精度,便于使仪表实现智能化,具有相应的灵活性和实用性。

| Abstract: | In order to realize the purpose of automatic measurement,automatic resistance tester consists of C8051F020 monolithic integrated circuit as the core element.Through the measured resistance constant current with known value passes,voltage drop on the resistor is input into single-chip A/D converter input port,after processing by single-chip microprocessor,the resistance value is displayed on LCD12864 system.By controlling relay switch,the resister tester can realize function of resistance automatic filtering,which meets the variability of test objects,improving measurement accuracy,and easily makes instrument to be intelligent,with appropriate flexibility and practicality. |
