摘要
简要介绍山西孝义地震台晋9-1井的观测概况,对2015年12月数字水位仪校测时发现的测量误差增大的原因进行分析,认为可能存在仪器零漂问题。通过与模拟观测资料对比,明确数字水位仪零漂特征,为今后观测提供参考。
This paper briefly introduces the observation survey of 9-1well in Xiaoyi,Shanxi province.the reasons for the increase of measurement errors found in the calibration of digital water level meter in December 2015 are analyzed.It is considered that zero drift of instrument may exist.By comparing with the simulation observation data,the characteristics of zero drift of the digital water level meter are clearly defined.It can provide reference for future observation.
