Abstract
Eccentric loading errors of a weighing cell () with a parallel guiding mechanism are determined and corrected or at least reduced. The weighing cell has a test weight actuating device (), by which at least one test weight () is positioned successively on at least three test weight support points () of the test load receiver () that do not lie in a straight line. A processor unit () uses a control signal (S) to position the test weight on the support points. A test weighing signal (T) is generated for each support point, and from these, eccentric loading errors are ascertained. A device for correcting the eccentric loading errors uses control signals (S) from the processor unit to make a geometrical-mechanical change in the parallel guiding mechanism, using a first and a second actuating unit.
