The relationship between instrument sensitivity and rotational stiffness of the pivot is revealed by analyzing the rotational stiffness equation of the cross-spring pivot. In order to eliminate the impacts of payload changes on instrument sensitivity, a cross-spring Hooke hinge with constant rotational stiffness is designed as the rotation unit of a 2-DOF static balancing instrument for unbalanced moment measurement of gimbaled devices. Certain amount of unbalance moments along certain direction are measured by the instrument and the synchronization sensitivity along x axis and y axis is investigated. Experimental results show that when the payload ranges from
