Abstract
An electronic balance with scale on top and with parallel guide rods whereby corner-load errors can be corrected by means of the inclusion of at least one leaf spring which is fastened to a load receiver and is supported on the other end on a fixed point of the housing. The magnitude of the correction can be adapted to the corner-load error of the unadjusted parallel guide by means of the selection of the spring stiffness of the leaf spring and/or by means of its effective length.
