ABSTRACT:
A combination weighing machine, which is typically used for packing a plurality of articles in each bag or the like, including a plurality of weighing balances for weighing a plurality of articles each at the same time, and arithmetic means for selecting some of these weighing balances so that the total weight of the articles thereon falls within a predetermined allowable range, the machine also includes zero-point correction means arranged such that, by applying a zero-point correction command signal from the outside, the loading operation of a selected balance is inhibited and, after the unloading operation, this balance is left vacant, and that, under such condition, the weight signal output from this balance is cancelled or nullified prior to arrival at the arithmetic means.
