Signal-coil calibration of electromagnetic seismometers [PDF]
Bulletin of the Seismological Society of America, 1995 AbstractWe show that electromagnetic (em) seismometers may be easily and accurately calibrated by removing a step of current from their signal coil, and simultaneously switching the signal coil to a recorder to capture the response. A theory is developed that obtains the damped generator constant, resonant frequency, and damping ratio from the output ...
