摘要
用电位差计校正电表实验是主要针对工科学生所开的一个电学实验。由于仪器较多容易出的故障也较多,所以怎样根据仪器故障现象尽快对故障可能存在的部位作出判断,然后排除故障,是实验课能否顺利进行的根本保证。
The experiment of correcting electric meter with potentiometer is an important electric ex- periment of students of engineering. But the instrument failures are often multiple faults because of there are more instruments in this experiment, then finding and shooting these failures is the funda- mental guarantee of the experiment carrying out smoothly.
