Abstract
A calibrating device for a balance including a load receiving unit for loads to be weighed, a load measuring unit and a lever mechanism serving for the force transmission between the load receiving unit and the load measuring unit, wherein the lever mechanism is coupled to the load receiving unit through a coupling area on an input side and to the load measuring unit through a coupling area at an output side, and wherein the lever mechanism further includes an additional coupling area, separate from the coupling areas on the input and output sides, for releasably coupling a calibrating force which is uncoupled during the normal weighing operation. The balance further includes a parallelogram guide means with two parallel guide members whose first ends are connected to each other through a deflectable member which is guided so as to be movable parallel to the direction of the calibrating force and which serves for the releasable coupling of the calibrating force, and whose second ends are connected to each other through a stationary member, wherein the coupling area serving for the calibration is connected to the deflectable member.
