| Abstract: | In this paper,a high current instrument is designed to measure AC /DC with Hall element,whose basic principle of the measurement is： showing the size of the measured current by measuring the size of magnetic field caused by measured current. The size of magnetic field is converted into the Hall voltage through the Hall sensor,and displayed on the LCD screen after a SCM processing. The current measurement ranges from 0. 1A to 500 A and measurement accuracy is up to effective 3-digit figures. The instrument provides the measurement of high DC with a better way. |
