IMPROVED CALIBRATION METHOD FOR AUTOMATIC CATCHWEIGHING INSTRUMENTS

The paper presents recent developments related to the establishment of a calibration procedure for automatic catchweighing instruments (catchweighers).The main purpose of the proposed calibration method is to provide a basis for traceable measurements of the catchweighers in the dynamic mode of operation outside of the legal metrology framework.The specifics of the instruments' operation in the dynamic mode are highlighted, the recent modifications in the calibration method and the uncertainty budget are outlined and the results of validation of the proposed method are presented.A good agreement of the performed validation experiments is shown, which could lead to the successful implementation of the procedure in practice.
