Could anyone provide information about the significance of calibration frequency and its value for CMG3T-120 seismometer with Reftek-130 as Digitizer?

07 March 2020 1 7K Report

Actually I want to calculate instrument response constant for correction of instrument response of CMG3T-120 seismometer.The formula to calculate that can be given as

C=A*sensitivity*2*pi*calibration frequency

A : Normalization factor

Richard O. Ocaya

With all other parameters considered,

C=kf .........(1)

Hence,

Delta C = (C. Delta f)/f ......... (2)

Therefore, the uncertainty in C directly depends on the drift in f.

This result (2) comes from applying variational calculus on equation (1).
