Description: 本文所设计的系统是基于AT89C52单片机控制的简易RLC测试仪。为了充分利用单片机的运算和控制功能，方便的实现测量。把参数R、L、C转换成频率信号f，然后用单片机计数后再运算求出R、L、C的值，并送显示。 转换的原理分别是RC振荡电路和电容三点式振荡电路。为了比较准确的测试而频率的计数则是利用等精度数字频率计完成。然后再将结果送单片机运算，并在LED显示器上显示所测得的数值。通过一系列的系统调试，本测试仪到达了测试标准。经过测试，
-In this paper, the system designed is based on AT89C52 single-chip microcomputer to control a simple RLC tester. In order to take full advantage of single-chip computing and control functions to facilitate the realization of measurement. The parameters R, L, C converted into frequency signal f, and then use the single-chip counts obtained after the operator R, L, C values, and sent to display. The principle of conversion is the RC oscillator circuit, respectively, and three-point oscillator circuit capacitance. In order to test more accurate frequency count is the number of frequency of use of complete accuracy. Then send the results of single-chip operation, and LED display shows the measured values. Through a series of system debugging, the tester arrived at the testing standards. After testing,
