发明名称 Calibration arrangement for an electronic balance
摘要 A method for adjusting a calibration arrangement of an electronic balance during the production process, wherein the calibration arrangement includes a transfer mechanism with a drive system, and wherein the calibration arrangement couples at least one calibration weight to the force-measuring device, said coupling being effected by the transfer mechanism transferring the calibration weight in a guided movement between a rest position and a calibration position. According to the method the distance between the end stops is determined by a counter system and stored into memory. Using the stored travel distance to calculate the rest position and the calibration position.

主权项 1. A method of adjusting a calibration arrangement of an electronic balance during a production process, said electronic balance comprising a calibration arrangement and a force-measuring device, said calibration arrangement comprising a transfer mechanism having a drive system, wherein the calibration arrangement couples at least one calibration weight to the force-measuring device, said coupling being effected by the transfer mechanism transferring the calibration weight in a guided movement between a rest position and a calibration position, wherein the method comprises the following steps: moving the calibration weight into a first end stop; moving the calibration weight into a second end stop; measuring a travel distance between the two end stops by the use of a counter system, wherein said travel distance is divided into travel steps measured incrementally; storing the number of said travel steps between the two end stops as a first parameter; subtracting from the first parameter a second number of travel steps representing a defined distance from the first end stop, storing the difference as a second parameter, wherein said parameter is the distance between a rest position and the first end stop; and subtracting from the second parameter a third number of travel steps representing a defined distance from the second end stop, storing the difference as the travel distance between the rest position and a calibration point.
