Abstract
An electronic balance with a force-transmitting device () has a calibration weight arrangement (). The arrangement includes a calibration weight () capable of being coupled to the force-transmitting device (). It also includes a transfer mechanism and a drive source to effect a guided movement of the calibration weight (). The drive source has an actuator () that cooperates with the transfer mechanism and consists, at least in part, of a shape memory alloy. The actuator () moves the calibration weight () through a structural change of the shape memory alloy as a result of a temperature change.
