【Abstract】 The JCZ-1 ultra broadband seismometer and CTS-1 very broadband seismometer are key equipment employed in National Digital Seismograph Network, the in-situ calibration of seismometer at seismostation is a very important operation for correct seismological observation.This paper describes the response of these seismometers for different calibration signals. The conditions to get correct calibration results for the broad band features of the seismometers is expounded. On the basis of the analysis of calibration error source the data processing method to improve the calibration precision is presented.更多还原
