Abstract: A method of improving pivoting of a wheel set for a scientific instrument, including an arbor pivoting or oscillating about a wheel set axis, the method including: static balancing of the wheel set to bring the center of gravity onto the axis; determining a desired value for the resulting unbalance moment of the wheel set about the axis, corresponding to a predetermined desired divergence between a first principal longitudinal axis of inertia of the wheel set, and the axis; setting the wheel set in rotation at a predetermined speed about the wheel set axis, the resulting unbalance moment is measured with regard to the axis; and adjusting a value of the resulting unbalance moment of the wheel set about the axis within a given determined tolerance with regard to the desired value.
