电子水准仪的精度分析与研究

Precision Standard of Electronic Digital Level

探讨了评价电子水准仪的精度指标,并利用TOPCON DL-101C电子水准仪和Leica NA3003电子水准仪对闭合环进行观测,对其精度进行了分析,结果表明,这两种仪器都满足一等水准测量的限差要求。

In this paper, the precision standard of electronic digital level （EDL） is analyzed. The precision analysis of the TOPCON DL-101C and Leica NA3003 is presented. The conclusion can be drawn that they all can be used in second-order leveling.
