Abstract
The invention relates to a method in a weighing system, in which method the mass of the bundle is weighed and recorded during both loading % and unloading mi_p of the bundle, during loading, the total loading mass mK_kok_j is calculated from the mass mi_c of one or more bundles weighed during loading and corrected using a correction factor Cj, the total unloading mass mp_kok_j is calculated from the mass mi_p of one or more bundles weighed during unloading, with the aid of the said total loading mass mK_COk_j and total unloading mass mp_kok_j′, a new corrected value Cj+1 is calculated for the correction factor Cj in order to adjust the weighing for the loading of the next load Kj+1. The invention also relates to a corresponding software product, an arrangement, and a material-handling machine.

18. A method in a weighing system, the method comprising:
-
lifting at least one bundle with a crane equipped with a weighing system, in order to form a load, weighing and recording the mass of the bundle during both loading and unloading of the bundle, calculating a corrected loading mass by correcting the recorded mass of one or more bundles weighed during loading using a correction factor, calculating a total loading mass from the corrected loading mass of one or more bundles weighed during loading, calculating a total unloading mass from the recorded mass of one or more bundles weighed during unloading, and calculating a new corrected value for the correction factor based on the total loading mass and the total unloading mass. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 34)

31. An arrangement in a weighing system having a crane for weighing a bundle lifted by the crane, the weighing system comprising a computation unit for calculating a mass of the bundle weighed by the weighing system and a memory for storing the masses, where the computation unit adjusts the weighing system based on the stored masses of the bundles, the weighing system operable to weigh the mass of each bundle of a load in connection with both loading and unloading of the bundle, in which the computation unit is arranged to
calculate a total loading mass from a mass corrected by a correction factor of one or more bundles weighed during loading, calculate, during unloading, a total unloading mass from a mass of one or more bundles weighed during unloading, and determine, based on the total loading mass and the total unloading mass, a corrected value for the correction factor in order to adjust the weighing of loading in loading of a subsequent load.
