Claim Text:
1. A calibration device for a force-measuring device, the force-measuring device having a force-measuring cell and a processing unit, comprising: an electrically controllable force-generating device coupled to the force-measuring cell at a coupling location so that a predefined force can be applied to the force-measuring cell for generating a measuring signal which correlates to the applied force which can be transmitted to the processing unit of the force-measuring cell for processing in reference to the predefined force and wherein the calibration device forms a functional unit with the force-measuring device when the calibration device is coupled to the force-measuring device; a first mechanical interface defining the arrangement of the calibration device in relation to the force-measuring cell according to a predetermined dimension; a second mechanical interface defining a vertical distance between the coupling location of the force-generating device and the first mechanical interface, the vertical distance conforming to a predefined value; a calibration control unit having continuous access to at least one predefined parameter representing a characteristic or operating condition of at least one of the force-measuring device and the calibration device; wherein the calibration control unit is connected by a communications link to the processing unit to exchange information signals and wherein the calibration control unit is adapted to generate control signals based on the information signals and the parameter for controlling the force-generating device and wherein the calibration control unit is configured with the ability to make autonomous decisions regarding the control of the force-generating device; and the first and second mechanical interfaces allowing the calibration device to be removably and modularly coupled to and used with various types of force-measuring devices, each of the various types of force-measuring devices having different requirements.
