摘要
为了研究寒区低温条件下数字水准仪的测量性能,针对天宝DiNi03和徕卡DNA03数字水准仪,在哈尔滨某高校校内通过选取不同的温度设置相应的测量周期,对所布设的水准线路进行了实验测量。测量结果表明:数字水准仪在寒区低温条件下仍然具有稳定的性能和较高的测量精度。
In order to study the measurement performance of digital level at low temperature in cold area,aiming at digital levels of Tianbao DiNi03and Leica DNA03,which were common on the market,in a university in Harbin,by selecting different temperatures,he corresponding measurement cycle was set,experimental measurements were carried out for the leveling line laid.The measurement results showed that the digital level still had stable performance and high measurement accuracy at low temperature.
