摘　　要：本文介绍了对低纬子午环从初调到精调 ,从解决一些明显的问题到发现一些潜在问题的调试过程 ,文章贯穿叙述了在对各种仪器误差测量新方法的正确性充分理解的基础上 ,在仪器已经成形而不能对其结构作较大修改的条件下 ,如何对部分问题作必要的修改和另一部分问题作回旋处理的作法 ,使得该仪器在具体的工艺水平和加工精度的条件下 ,接近于采用新的误差理论后所应达到的观测精度。The process of adjusting the LLMC is described in this paper,which starts from the initial adjustment to the fine adjustment and from solving some obvious problems to discovering some later ones.Based on the sufficient comprehension of correctness of the new method for each instrumental error measurement,and being in the condition that the instrument has been made and the large-scale modification can not be done,we have improved on some parts and treated others in a circular manner.This makes the instrument in the concrete level of technology and manufacturing accuracy close to the observation precision that should reach after a new error theory is adopted.
