Title: Determining parameters of vibration or inclination of seismometer
Inventor: UNTERREITMEIER ERHARD DR
IPC: G01C25/00
Filed: 1997-03-12
Granted: 1998-10-01
Abstract: The determination method is carried out by a seismometer, which is rotated about a locally fixed axis for a deflection measurement, which is inclined at a predetermined axis inclination compared to the vertical. The rotation takes place from an original alongment (phiA) in preset angular steps to a final alignment: phiE = phiA + n <.> 180 deg  (with n a whole number). So that at each angular step, a characteristic deflection signal: U(z(phi)) for the deflection (z) of the mass element is determined, depending on the rotation angle (phi). After the deflection measurement the deflection signals: UA(z(phiA)) and UE(z(phiE)), their difference (UA-UE) and the settings (phiNS) of the function U(z(phiNS)) = 0 are determined and processed.
