说明：  自动电阻测试仪程序：自动电阻测量仪设计采用C8051F020单片机作为核心,采用高精度恒流源驱动的伏安法针对不同档位电阻进行测量,选用MAX1241高精度A/D转换器进行模数转换,具有100Ω1、kΩ、10 kΩ1、0 MΩ四个量程,电阻测量精度均达到0.4 。各档位之间均可以实现手动分档或自动档位切换,并能根据键盘输入的电阻值和误差值进行筛选,对于不合格的电阻能够给出语音提示,该系统同时可以自动测量连续变化的电阻值并实时显示及绘制变化的曲线。自动电阻测量仪体积小、精度高、运行稳定可靠,具有一定的实用价值
(Automatic Resistance Tester Program: Automatic resistance meter designed using C8051F020 microcontroller as the core, high-precision constant current source driven voltammetry measurement of resistance against different stalls, the choice MAX1241 precision A/D converter analog to digital conversion, has 100惟1, k惟, 10 k惟1, 0 M惟 four ranges, resistance measurement accuracy reaches 0.4 . Both can be achieved between each gear manually sub-file or automatic gear switching, and according to keyboard input resistor values ​ ​ and error values ​ ​ were screened for resistance to give unqualified voice prompts, the system can automatically measure changes continuously while The resistance value and real-time display and rendering the curve. Automatic resistance measuring instrument, small size, high accuracy, stable and reliable, has a certain practical value)
