摘　　要：数字水准仪作为高精度水准测量仪器广泛应用于各种工程测量中,但在使用之前需通过计量检定机构的检定,以确保其测量值的准确,满足规范要求。传统的室外检定法易受各种外界环境的影响,给检定工作带来诸多不便。为此,文中提出了一种新型数字水准仪室内检定系统,克服了室外法的各种缺陷。实验数据表明,该系统对数字水准仪主要检定项目的检定结果均要优于室外法,这对于全室内数字水准仪检定系统的研制具有一定参考意义。As a high-precision leveling instrument,the digital level meter is widely used in various engineering surveys,but it needs to be verified by the measuring mechanism before use by ensuring that its quantity accurately meets the specification requirements.The traditional outdoor verification method is susceptible to various external environments,which brings many inconveniences to the verification work.To this end,the paper proposes a new type of digital level indoor verification system that overcomes various shortcomings of the outdoor method.The experimental data shows that the verification result of the main calibration items of the digital level meter is better than the outdoor method,which has certain reference significance for the development of the whole indoor digital level calibration system.
