摘要:

i角是衡量水准仪性能最重要的指标之一.本文以DS3-Z型微倾水准仪和DSZ3-1型自动安平水准仪为例,给出了平行光管检验校正台校正光学水准仪的具体步骤.实验表明,校正后DS3-Z型与DSZ3-1型水准仪的i角分别从130.4″减小至17.2″、75.0″减小至10.2″,校正结果符合《国家三、四等水准测量规范》的要求.

Abstract:

Thei-angle is one of the most important specifications of levels. Concrete procedures to calibrate thei-angle of optical levels using a calibrator stand with collimators are presented, taking the DS3-Z level and DSZ3-1 level as examples. The experiments show that thei-angles of DS3-Z level and DSZ3-1 level are respectively reduced from 130.4″ to 17.2″ and 75.0″ to 10.2″ after calibrating, and that the calibrating results accord with National Specifications for the Third and Fourth Order Leveling.

Key words: calibrator stand with collimators; tilting optical level; automatic optical level;i-angle; leveling
