ABSTRACT:
An apparatus and method for calibrating an automatic weighing machine is provided, having means for maintaining the value of an electronic signal indicative of tare weight within a predetermined range of an ideal value in order to ensure adequate signal range is available for high resolution of net weight. In addition, an analog-to-digital (A/D) converter having an adjustable gain is provided which interfaces the analog signal indicative of total gross weight (tare plus net) to a processor means. Means are provided within the processor means for adjusting the gain of the A/D converter in response to changes in the selected target weight for a package of product. Since the range of analog signals indicative of total weight depend on the selected target weight, the gain is adjusted in response to a change in target weight so the full range of digital values remain responsive to the range of analog signals.
