本文通过数学计算,对度盘几何中心在 XOY 坐标上沿 X、Y 轴与指针旋转中心偏移不同距离时,影响指针回零的示值误差进行分析.并提出排除误差的方法。
In this paper, we analyze the indication errors that affect the zeroing of the pointer when the geometric center of the dial is offset by X, Y axes and the rotation center of the pointer on the XOY coordinates by mathematical calculation, and propose a method to eliminate the error.
