摘　　要：为克服传统的外加交流测量法电源波动易引起偏差和文氏电桥测量法参数调节复杂等问题,文章设计了以89C51单片机系统为核心的RLC测试仪,实现RLC参数的自动测量和显示,该测试仪具有自动量程转换、实时显示等功能。通过Multisim软件,对电阻、电容以及电感所组成的振荡电路进行仿真设计,系统结构合理、操作便捷,且测量准确度高、响应速度快、测量范围广。To overcome the traditional method of measuring external AC power fluctuations caused by the deviation and the electrical bridge method of regulating complexity, this paper introduces the design of RLC tester based on 89C51 microcontroller as the core of the system, realize the RLC parameter automatic measurement and display, the instrument has automatic range conversion, real-time display and other functions. The oscillation circuit of resistor, capacitor and inductance is simulated by Multisim software. The system is compact, easy to operate, and has high measuring accuracy, fast response and wide measuring range.
