Abstract: This invention relates to an improvement of a control system for a combined weighing apparatus which in more detail includes a plurality of measuring hoppers supplied with products to be measured from transfer means for measuring weights of the products to select a weight equal to or near to a set weight from any combinations of the measured weights, and more particularly to an improvement of a condition-setting system and a measuring hopper combination-selecting system capable of remarkably facilitating setting of data of set weight, transfer conditons and the like by means of the condition-setting system when products to be measured are changed and capable of shortening the time for selecting a combination of measured values so as to enable the combination operation to speed up.
