摘　　要：拓展教学内容,给出创新空间,将课堂实验当作仪表厂工程师的实际工作来对待.增加对改装电表确定准确度等级的内容,并结合国家规定的检定规程和实验误差思想,从物理实验角度讨论了简略的电表准确度等级确定原则,以加深学生对常用电表知识的理解,充分调动学生的学习积极性和创新意识.This paper discusses how to guide students to regard experiments as making electric meters, let them feel as if they were engineers working at a factory while performing the experiments. Teaching content is expanded. Space for students to create is offered. Training of practical operation is gained greatly as well as the students＇ achievement. Content of judging the accuracy level of modified electric meter is mentioned. National verification standards and the thought of experiment - errors is combined to discuss the brief principle of judging the accuracy of electric meter from the angle of physics, so the students＇ understanding of the knowledge of common electric meter can be deepened and the enthusiasm of the students, as well as the creativity of them can be aroused greatly.
