光学微倾水准仪等级测定

Optical Tilting Level Level Determination

国家计量法中规定,测绘行业所使用的仪器本身归属于计量仪器的范畴,仪器在出厂、出售、使用中应当通过我国的计量检验,确保计量仪器性能的合格。光学微倾水准仪是工程中常用而且重要的一种测绘仪器[1],为了保证水准仪测量数据的准确、精确,确实保证工程质量,不但要熟悉仪器各个部件而且要检验仪器各类性能是否达到计量的精度,对初始购买、正在使用和维修的仪器需要进行仪器的检验与校正,确保仪器在额定的等级内使用,本文主要对使用中的水准仪进行等级测量,并且与额定仪器等级进行比较分析。

National Metrology Law provides that,instrument used in surveying and mapping industry itself belongs to the instrument category of instruments in the factory,sale,use should be through the econometric test in our country,to ensure the metrological performance of instrument.Optical tilting level is commonly used in engineering and an important instrument of surveying and mapping,in order to ensure the level measurement data is accurate and precise,really ensure the quality of the project,not only to be familiar with instrument parts and all kinds of performance testing instrument meets the precision of measuring instruments,is being used to the initial purchase,and the need for maintenance and calibration test instrument,to ensure that the instruments used in the rated level,this article mainly carries on the measurement of the grade level in use,and compared with the rated grade of instrument.
