Abstract
A method for tuning one or more sensor devices is provided, wherein each sensor device comprises one or more proof masses configured to move in response to an external stimulus of interest, and the one or more proof masses are also susceptible to move in response to one or more stimuli other than the external stimulus of interest. Each sensor device also comprises one or more pick-off mechanisms respectively associated with each of the one or more proof masses. The one or more pick-off mechanisms is proportionally responsive to a motion of the sensor device. The method for tuning includes adjusting gain of one or more of the pick-off mechanisms to reduce an output of each sensor device when the one or more proof masses move in response to the one or more stimuli other than the external stimulus of interest.
