摘要
文章从霍尔电流传感器的工作原理入手,重点探讨了校准电流传感器示值误差的计量标准器具、校准步骤以及校准时的注意事项,最后对校准结果进行了测量不确定度的评定。
The article starts with the working principle of the Hall current sensor,and focuses on the measurement standard instruments for calibrating the indication error of the current sensor,the calibration steps and the precautions during calibration.Finally,the measurement uncertainty is evaluated for the calibration results.
