Abstract
A calibration weight assembly () has at least one calibration weight () and a transfer mechanism, and is used with a gravimetric force-measuring device () having a fixed region (), a load-receiving region (), and a measuring sensor (). The transfer mechanism has at least one poly-stable positioning element (), 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.
