The calibration weight arrangement for an electronic balance with a force-transmitting device ( 1 ), includes a calibration weight ( 14 ) capable of coupling to the force-transmitting device ( 1 ). The calibration weight ( 14 ) is moved vertically by a transfer mechanism and a drive source to establish and to release the force-transmitting contact between the calibration weight ( 14 ) and the force-transmitting device ( 1 ). The transfer mechanism has at least one resetting element ( 22, 37, 38, 40, 43 ) and a lifting system configured as a knee joint linkage ( 17, 117, 217 ). The resetting element ( 22, 37, 38, 40, 43 ) and the lifting system work together to arrest and cushion the calibration weight ( 14 ) if the balance is shocked, dropped or hit.
