电阻电容电感测试仪的设计与制作

Design and Production of the Instrumentation,which could Test the Resistance、the Capacitance and the Inductance

该电阻电容电感测试仪以AT89S52单片机为控制核心,通过测量频率来间接测量电阻器的阻值、电容器的容量和电感器的电感量,并对测试数据和测试结果进行保存记录,可调出最近十次的测量结果并显示测试的时间、元件类型、参数;所有测量的量程均能自动转换量程,并显示相应的提示语句。

The core of the tester for the resistance, the capacitance, the inductance was AT89S52. The resistance, the capacitance or the inductance was tested indirectly by testing the frequency. The dates and the results were stored in the core. The last ten testing results could be recalled, at the same time, the testing time, the type and the parameters of the component were displayed. All of the testing range were changed automatically, and the corresponding languages were displayed simultaneously.
