Claim:
1. A cell for weighing a load on a weighing load receiver, the cell having weighing electronics associated therewith and a vertical load application axis, the cell comprising: a parallel guiding mechanism which comprises: a test weight actuating device, arranged to position at least one test weight successively at the at least three test weight support points, wherein: a processor unit, configured for generating control signals for the test weight actuating device, to control the positioning of the at least one test weight on the test weight support points and to receive, from the weighing electronics, a test weighing signal associated with each test weight support point concerned and also configured to ascertain eccentric loading errors of the weighing cell on the basis of the received test weighing signals, and a device for acting upon the ascertained eccentric loading errors, comprising at least a first and a second motor-operated actuating unit controlled by additional control signals from the processor unit, to generate a geometrical-mechanical change in the parallel guiding mechanism assigned to the actuating unit concerned, the geometrical-mechanical change associated with an eccentric loading error component, thereby correcting or at least reducing the eccentric loading errors.
