数字电位差计的设计与研制

Design and research of the digital display electric potential difference meter

介绍一种采用先进的电子技术设计出新型高精度的电位差计．该仪器电子线路用高稳定性的可调电源取代传统电位差计的干电池和标准电池，用高灵敏度的电子检流计取代机械检流计．配上单片机，通过对可调电源的测量，转换成对被测物理量的测量。

A new high precision electric potential difference is introduced by adopting the advanced electronic technigue, in which the dry and standard cells in the electron line of the traditional meter are replaced by the stable regulator mains, and the mechanical electronic detector is replaced by the high sensitive one.With the help of the single chip computer, the regnlator mains and the physic quantity can be measured, thus the value of electronic motive force can eventually be measured.
