摘　　要：本文以南方DL-2003A型号高精度数字水准仪为例,在海拔3 000 m以上区域进行了二等水准观测,通过与Leica DNA03型号高精度数字水准仪观测成果进行对比分析,结果表明国产仪器在仪检指标方面达到DSZ05级别,在观测精度、性能稳定等方面与进口仪器相当,满足国家二等水准观测要求。In this paper, the DL-2003A high-precision digital level instrument was taken as an example and the second-class level observation was carried out in the area above 3000 meters above sea level. Comparing the observation results with the Leica DNA03 high-precision digital level instrument, it was showed that the domestic instrument had reached the level of DSZ05 in terms of instrument inspection indicators. In terms of observation accuracy and stable performance, it was equivalent to the imported instrument and meets the requirements of national second-class standard observation.
