目前,角度计量仪器的度盘读数形式常见的有单边读数和度盘对径符合成象读数两种。由于读数形式的不同,度盘偏心引起的示值误差也不同。偏心量相同时,对径符合成象的示值误差小,单边读数的大。本文介绍一种度盘偏心位置的判断及其调整的“公式图示法”,供参考。设度盘的刻度中心相对于回转中心的偏心 At present, the angle measuring instrument dial readings common forms of unilateral readings and dials on the road coincide with the image readings of two. Due to the different forms of readings, the indication error caused by the eccentricity of the dial is also different. When the eccentricity is the same, the indication error of the coincidence image of the diameter is small, and the reading of the single side is large. This article describes a judgment of eccentric disc position and the adjustment of the “formula diagram” for reference. Set the scale center of the disc relative to the center of rotation eccentricity
