Abstract

PURPOSE:To prevent erroneous zero point compensation by storing the zero point compensation value at the previous time and obtaining the state before the zero point compensation by using said memorized value when a weighing signal is largely changed in zero point compensation work. CONSTITUTION:In zero point compensation works, the counted value of an up and down counter 6 at the previous time, e.g., the previous zero point compensation value is stored in a side memory 10. During the zero point compensation, if the weighing signal is largely changed due to, e.g., erroneous touching to the scale, this change is detected by a weight change detecting circuit 18, the zero point compensation value at this time is offset, the previous zero point compensation value is returned to the up and down counter 6, and the state before the zero point compensation is restored.
