摘要
阐述了箱式电位差计操作麻烦、费时及容易产生系统误差等原因．若改用数字式电位差计校表，就可以解决这些问题．UJ33 D型数字电位差计可数字直读发生和测量电压值；测量范围是0～2500．0 mV，准确度等级是0．01，最小分辨率是0．01 mV．说明用数字式电位差计校准电表的原理，对电阻R1、R2及Rs取值进行了研究，并对实验设计进行了分析研究．
The operation trouble , time -consuming and system error of box -type potentiometer are ex-pounded.These problems can be solved if the digital potentiometer is used .UJ33D type digital potentiometer can occur and digital direct voltage measurements;Measurement range is 0-2500.0 mV, the accuracy level is 0.01, the minimum resolution is 0.01 mV.The principle of calibrating the electric meter with digital potentiometer ,The values of resistance R1 , R2 and Rs were studied, and the experimental design was analyzed .
