摘要
基于试验和实践，讨论了数字水准仪的特性和误差来源及其对观测结果的影响。在此基础上阐述了该仪器应用于区域精密水准测量中应予关注的各种问题和提高精度的措施。指出：应制定有关该仪器的测量规范。
On the basis of surveying principle,the features and error source of the digital leveller is discussed, hence the law, the appropriate measures and the instrument improvement that must be followed in the precision regional levelling are given. It is pointed out that the surveying regulation on this leveller must be formulated.
