... If the device is oriented such that the projection of gravity onto all three axes is nonzero, the effective sensitivity is reduced, causing an increase in the dead zone angle. Therefore, evaluation needs to be performed for specific appli- cation uses to determine the optimal setting for the dead zone. Rev Page ...
