A calibration weight assembly (100, 200, 300, 400, 500) has at least one calibration weight (150, 550, 750) and a transfer mechanism, and is used with a gravimetric force-measuring device (110, 210, 310, 410, 510) having a fixed region (111, 211, 311, 411, 511), a load-receiving region (112, 212, 312, 412, 512), and a measuring sensor (140, 540). The transfer mechanism has at least one poly-stable positioning element (561, 571), a first stable state of which defines a calibration position (KP) and a second stable state of which defines a resting position (RP) of the transfer mechanism. The at least one calibration weight can be coupled with the load-receiving region. The transfer mechanism, as actuated by the measuring sensor, transfers the at least one calibration weight from the calibration position to the resting position, or vice versa.
A calibration weight assembly for a gravimetric measuring device with a force-measuring device that comprises a fixed region, a load-receiving region and a measuring sensor, the calibration weight assembly comprising:
