Abstract
A method and apparatus for automatically adjusting the zero point of a weighing machine includes producing, in the form of a digital value, an initial zero-point correction value when the weighing machine is free of a load. The difference value between an unloaded weight value, which is produced by the unloaded weighing machine, and a value obtained by converting the digital value into an analog value, is calculated. The difference value is compared with a preset value, and digital values are sequentially converted in accordance with the result of the comparison operation to render the difference value equal, or nearly equal, to the preset value.
