| Abstract: | The potentiometer is often used to accurately measuring different electrical quantities,such as elec-tromotive force,voltage,current,resistance and so on. The meter can be calibrated by the potentiometer too. In this paper,a new physical experiment has been offered. The UJ31 potentiometer is often used to current meter by balancing different indicator calibration laboratory. Through the comparative analysis on the test data, the correction table accuracy class and measuring results of different balance indicator are obtained. |
