Automatic Weighing Device: a weighing device that weighs without the intervention of an operator and follows a predetermined program of automatic processes characteristic of the device.
Non-Automatic Weighing Device: a weighing device that weighs discrete loads and that requires an operator's intervention during the weighing process, such as to deposit the load to be measured on the weighing and load-receiving element and to remove it therefrom or to obtain weighing results.
