| Abstract: | The seismometer and data acquisition of Ningxia Lingwu seismic observation well were replaced at the end of December 2018.After replacement,the seismometer model was GL-S2 B borehole short period seismometer,and the data acquisition model was EDAS-24 GN data acquisition.After the completion of the replacement seismometer and data acquisition,technicians of Beijing port seismic instrument and Equipment Co.,Ltd.and Ningxia Seismological Bureau carried out a series of parameter measurements,such as azimuth correction,step calibration,sine calibration,station based noise power spectral density test,etc.,to ensure the reasonable and standardized installation of the underground seismometer in Lingwu,Ningxia,so as to ensure the future Ningxia Lingwu underground seismometer operates normally and efficiently.And Ningxia earthquake monitoring work is carried out orderly. |
