摘　　要：通过仪器电路改进、程序编写等工作,成功改进了数字电流表。改进后的电流表具有量程自动切换功能,实现了对原有数字电流表的量程保护。经实验测试表明,改进后电流表运行稳定,测试结果正确。By optimizing electric circuit and writing program,the galvanometer has been made better success-fully. The improved galvanometer can switch the range automatic when necessary,so it can protect the range from burning itself. Through the testing,machine works well,and experiment result is right.
