摘要
针对目前检测直流大电流使用的模拟指针式仪表读数不直观、误差较大等弊端，给出了一种用单片机设计的数字表头．文中给出了检测器的软硬件设计．对７５Ａ直流大电流实际检测表明，所设计的数字检测器性能稳定、抗干扰能力强．
In this paper,a digital instrument is introduced to test the large DC current for there are some disadvantages in the traditional analog instrument ,such as non visual read out and big error.And the hardware and software designs based on micro controller are also given.It is testified that the instrument has stable performance and stronge anti-interference when measuring 75 A DC current.
