一、跳动误差及其检测原则跳动误差是指被测实际要素纬基准轴线作无轴向移动的回转时,指示器在给定方向上测得的最大与最小读数之差。跳动误差这一项目本身就是根据“测量跳动原则”定义的,因此它的误差测量方法与误差定义是一致的,不需要再用最小包容区的概念进行评定,可由测量过程读数直接得出跳动误差值。但是,要获得准确的误差值,必须遵守以下检测原则: First, the beating error and its detection principle Beating error refers to the measured actual element latitude axis of reference for the axial movement of the rotation, the indicator measured in a given direction of the difference between the maximum and minimum reading. The runout error itself is defined by the “measuring runout principle” and therefore its error measurement method is consistent with the definition of error, eliminating the need to re-use the concept of minimum containment area can be assessed directly from the measurement of the beat error value. However, to obtain accurate error values, the following testing principles must be observed:
