Abstract
Abstract A system for successively weighing a plurality of articles, computing the value of each weighed article and printing records of the weight and value of each article having two different modes of operation. In a first operating mode, a stored tare weight for the article container and stored price information are automatically cleared either each time a record is printed or each time a weighed article is removed from the system. The price information may be in the form of either price per unit weight or price per fractional unit weight. In a second operating mode, the price information is restricted to price per unit weight and the stored tare weight and price information are not cleared automatically.
