The article aims to present progress in the development of methods for calibration of automatic weighing instruments (AWIs), which operates in dynamic mode. The specificities of the calibration of the AWIs in the dynamic mode of operation are highlighted. For automatic catchweighing instruments and automatic gravimetric filling instruments, basic information about the measurement method, error model and measurement uncertainty contributions are given. Several approaches are presented for determining the reference mass of the test loads on the control weighing instrument, including the related analysis of the air buoyancy correction and influence of the density of the test loads. The use of harmonized and validated methods will, when finalised, enable a traceable calibration of the AWIs in a dynamic mode of operation.
