  • Patent number: 4375243
    Abstract: An electronic scale is provided with two or more load cells in which the first load cell covers a low load range, and each successive cell covers a greater load range than the preceding cell. The cells are connected mechanically in tandem such that a load on the scales is applied to each cell simultaneously. Electrical signals from each load cell when performing a weighing operation are processed by a microcomputer to digitize the signals and to select the signal coming from the first load cell in the tandem connection which is not overloaded. The microprocessor scales the measurement signal and displays the weight on an alphanumeric readout. Memory circuits are included for storing tare weights and for storing unit weights during counting operations. When a number of units in a group is to be counted, the microprocessor divides a measured weight by the unit weight and outputs the count to the alphanumeric readout display.
