摘要
介绍了一种箱式直流单臂电桥的快速调节方法。用它测量电阻时不用粗测待测电阻,而直接进行电桥平衡的调节,测量过程简单、快捷。
A rapid adjustment method for the QJ -23a box-type single arm D. C. bridge is intro- duced in this paper. With this method, a coarse measurement for the resistant is no longer needed. The experimenters can directly regulate the electric bridge to be balance. Therefore, the measuring process is more simple and quick.
