Abstract
PURPOSE: To obtain a weighing machine accompanying no deterioration of weighing error in a small weighing division even when the weighing indication error is decreased by carrying out the predetermined processing of a digital value corresponding to the load value of a predetermined resolution in the total weighing division by way of a minimum scale change-over circuit in correspondence to the weighing division.
CONSTITUTION: The digital weighed value having a predetermined resolution over the total weighing division due to a load cell 1, and A/D converter 3 and the like is compared with a plurality of set values and a circuit 4 renders output lines into high levels l1, l2... in an alternative way. By this procedure, respective figures of calculated values added to a minimum scale change-over circuit 5 are applied as they are to the indication part 6 in response to the calculated value or the content of LSB is cut down, and they are converted into predetermined values so that they are applied to the indication part 6. Accordingly, the minimum scale becomes substantially larger as the weighing division becomes larger. Therefore, an electronic weighing machine accompanying no deterioration of the weighing error in the small divigion even when the weighing indication error in the large weighing division is decreased.
