A Intelligent Method for Measuring the Value of Capacitor

本文设计的电容测量装置 ,采用 C-T电路 ,将电容量 C转换成与之对应的振荡周期 T,经缓冲整形后送入 CPU进行测量数据处理 。

The method for measuring the value of capacitor introduced in this paper adopts C T circuit, which can translate value of capacitor to oscillation cycles and transmit its shapped waveform to CPU for data processing and to display the measuring results in digits. In the paper, not only the design of hard ware and software are presented, but also the cause of measuring error is analyzed.
