ABSTRACT:
The invention suggests for an electronic balance with a balance scale (1), with a parallel guide for the balance scale (1), with at least one sensor which measures the torques transferred from the balance scale (1) to the parallel guide, with storage means in the electronic circuitry of the balance in which means the magnitude of the corner-load inaccuracies of the parallel guide is stored in the form of corner-load correction factors and with switching means or program parts in the electronic circuitry of the balance which correct the weight value outputted from the measuring system on the basis of the output signals of the sensor or sensors and of the stored corner-load correction factors that controllable signals (10-13) are provided which designate the corners and sides of the balance scale (1). The signals can be formed by light sources adjacent to the balance scale (1) or in the corners or on the sides of the display field (9). The use of individual segments of the 7-segment numbers (3) of the balance display is preferred. An operator control can be achieved with these signals when readjusting the corner-load freedom of the balance.
