Abstract:
1. A force-transmitting mechanism of a gravimetric measuring instrument, the force-transmitting mechanism comprising: a stationary portion; a load-receiving portion; a measurement transducer, arranged on the stationary portion and joined to the load-receiving portion through a force-transmitting connection that acts either directly or by way of: at least one coupling element and at least one lever; a calibration lever, comprising a first and a second calibration lever arm, the respective calibration lever arms defined by a fulcrum that is mounted on the stationary portion; a calibration weight, rigidly connected to the first calibration lever arm; and arranged between the second calibration lever arm and either the at least one coupling element or one of the lever arms of the at least one lever or the load-receiving portion, a parallel-guided coupling means, divided into a fixed coupling part and a parallel-guided coupling part which comprises a first and a second parallel element that are arranged parallel to each other, with the fixed coupling part and parallel-guided coupling part arranged to transmit a tractive or a compressive force between the respective coupling parts; so that the first and second parallel elements, in order to absorb relative traverse displacements that occur in transmitting a force through the parallel-guided coupling means, tie the second calibration lever arm to at least one of: the load-receiving portion, the at least one coupling element, the at least one lever arm.
