ABSTRACT:
Improved electronic scale system for weighing, computing a value and printing a label showing the weight, price per unit weight and the computed value for each of a plurality of successive articles. An integrated circuit microcomputer is periodically supplied with the article weight from a load cell scale and is supplied with the price per unit weight either from a manual keyboard or automatically from a commodity plate in a label printer. After the system corrects for scale error, checks for scale no motion, compensates for any tare weight and checks various interlocks, the microcomputer computes an article value. A no motion signal is generated by the microcomputer when a predetermined number of successive weight measurements deviate from one another by no more than a predetermined small fractional weight less than the least significant weight digit used by the microcomputer in computing an article value. After the above operations are performed, the microcomputer causes a printer to print an article label bearing the corrected weight, the price per unit weight and the computed value.
