Summary:The arrangement has a calibration weight that is connected with a power transmission device, a transfer mechanism and a drive for controlled movement of the weight. The drive has an actuator (16) that cooperates with the transfer mechanism and partially includes a shape memory alloy. The actuator moves the weight by changing interior structure and/or crystal structure of the alloy caused by temperature change.
