Abstract
A weighing machine has a weighing conveyor with a conveyor belt supported by a load cell and uses a digital filter to eliminate high-frequency components of weight signals from the weighing conveyor. In order to improve accuracy of measurement, operating conditions of the digital filter are set with regard to the length of the object to be weighed. Alternatively, time required for the object to be completely on the conveyor belt may be calculated or the timing for the zero-point adjustment for the load cell may be adjusted accordingly.
