Improved electronic apparatus for weighing and computing the value from the weight and price per unit weight, for each of a plurality of successive weighing operations. An integrated circuit microcomputer is supplied with the article weight from a load cell and an analog-to-digital converter. The price per unit weight is supplied from a manual keyboard. The microcomputer includes as an arithmetic logic unit, data registers and sequence controller which is programmed to correct for scale errors, to check for no motion of the scale, to compensate the measured gross weight for any tare weight, to check various interlocks, and to compute an article value for each successive weighing. Null or zeroing and tare interlocks, checks, and safeguards are provided to reduce the possibility of fraud.
