<p>Improved apparatus for weighing and computing a value for articles. An integrated circuit microcomputer is supplied with the gross article weight from a scale and with price per unit weight data from a manual keyboard. Tare weight data may be entered either through the manual keyboard or automatically from the scale. The microcomputer computes a net weight and a value for each weighed article. The net weight, the price per unit weight and the value are indicated on a digital display and may be printed on a label. Filtering circuitry prevents jitter in the article weight supplied from the scale to the microcomputer and the display caused by small vibrations in the article or the scale.</p> |
