Abstract

PURPOSE:To increase the range of measurement, by switching the range to a proper level based on the range selection signal obtained from a current-voltage converting means. CONSTITUTION:A load 3 is put on a weighing scale 2, and an A/D converter 10 supplies the load data to the input terminal of a CPU13. Based on this data, the CPU13 obtains a proper range. The obtained range selection signal is delivered through the 2nd output terminal to be supplied to the control input terminal of a current-voltage converter 12. The range selecting action is stopped when the selected range is set at a proper level. This proper range is kept, and the weight of the load is displayed.
