Abstract
A calibration weight 100 for a gravimetric measuring instrument includes a calibration weight base module 101 which is equipped with at least one attachment area 106. The calibration weight 100 further has at least one positioning means 104 and at least one transfer element 105. The attachment area 106 allows supplemental weights 102 to be built onto the calibration weight base module 101; the positioning means 104 serves to position the calibration weight 100 in relation to the calibration weight arm 20; and the transfer element 105 serves as the place through which the transfer mechanism lever 31 applies its force and effects a transfer.
Claims20
A gravimetric measuring instrument, comprising:
- a floor part, defining a footprint area of an interior space of the instrument;
- a weighing cell having a load-receiving part and a stationary part, the weighing cell connected to and held in fixed position relative to the floor part, a height of the load-receiving part above the floor part defining a height of the interior space;
- a calibration weight arm connected to the load receiving part;
- a calibration weight, comprising:
- a calibration weight base module;
- at least one supplemental weight;
- and
- at least one attachment area formed on the calibration weight base module for attaching one of the supplemental weights thereto;
- and
- a transfer mechanism for coupling the calibration weight to the calibration weight arm and for uncoupling the calibration weight therefrom, the transfer mechanism connected to the floor part;
- wherein the calibration weight base module and the supplemental weights are sized and shaped to conform to a remaining shape and volume of the interior space after placement of the weighing cell therein.
