| 摘 要： | 环境温度是影响数字水准仪性能的关键因素。测试温度对国产数字水准仪i角的影响,发现当仪器内外温差较大时,仪器i角的变化显著。测试结果表明,i角设置与测试、水准测量都需要在仪器内外温度平衡时,才能够获得可靠的成果。

| Abstract: | Environment temperature is the key factor affecting the performance of digital level. The influence of temperature on the collimation error of digital level is tested practically, which is that the collimation error changes dramatically when the temperature difference inside and outside of the instrument is big. The test results show that reliable results of collimation error set-up, test, leveling can only be achieved when the temperature inside and outside of the instrument is balanced. |
