文档介绍：摘要
目前对于数字水准仪的各种精度的检测,,由于这种方法存在一些缺陷,例如外业工作量大,易受外界环境条件、观测者读数水平以及已知点成果精度等的影响。所以这种方法不能较客观的评价仪器的本身精度。基于上述,本文主要论述了数字水准仪的原理与特点,分析总结了数字水准仪的误差源及其影响的大小,并深入的介绍了仪器检定项目和方法,从而为了解和掌握数字水准仪的工作原理、误差分析以及水准仪的检定作出系统的分析。

Abstract
At present for the detection of various precision digital leveling instrument, there is no a set plete and detailed verification regulation. Some just field observation way, because this method has some ings, such as industry workload, vulnerable to read number level of known points and the accuracy of the results and effects of environmental conditions, the observer. So this method can't objectively evaluate the accuracy of the instrument itself.. Based on the above, this paper mainly discusses the principle and characteristics of digital leveling instrument, the analysis summarizes the size of digital leveling instrument error sources and their effects, and deeply describes the instrument calibration items and methods, so as to understand and grasp the working principle of digital leveling instrument, error analysis and leveling instrument verification system to make the analysis.

绪论

迄今为止,几何水准测量仍是传递高程精度最高的一种方法,还不能被别的方法所替代,因此一直运用至今。但是传统几何水准测量存在一些缺点,比如存在测量速度
