摘要
本文以利用实验室废旧的500型指针式万用表为实验对象,开展创新性实验设计,将500型指针式万用表电阻档扩展了R×30kΩ档位电阻档,既锻炼了学生的动手能力和创新能力,又加深了学生对万用表的理解,还补充了创新实验室的仪器.
In this paper, an innovative experimental design is implemented on a wasted 500- model analog multimeter. The R×30kΩresistance range is extended in the 500-model analog multimeter, which trains the students＇ ability and innovation, and deepens their understanding of the multimeter. The innovative laboratory instruments are also complemented.
