The invention concerns a calibration device () for a force-measuring device (), specifically a balance, with an electrically controllable force-generating means () designed to be coupled to a force-measuring cell () of a force-measuring device () in such a way that a predefined force (F) can be applied to the force-measuring cell (), so that the latter generates a measuring signal (S) which correlates to the applied force (F) and which can be transmitted to a processing unit (, PU), where it can be processed in reference to the predefined force (F). The calibration device () includes a calibration control unit (CCU) which has access to at least one predefined parameter (P) characterizing the force-measuring device (() and/or the calibration device (), wherein the calibration control unit (CCU) can be connected by way of a communications link () to the processing unit (, PU) in order to exchange information signals (S) with the latter, and wherein the calibration control unit (CCU) is configured to generate control signals based on the information signals (S) and the parameter (P) in order to thereby control the force-generating means ().

Calibration device for a force-measuring device, and force-measuring device

Correction coefficients which permit effective linearization of an electronic scale over a measurement range may be determined by loading the scale individually and in combination with loads, at least one of the loads being unknown and uncalibrated.
