摘要:
An electronic balance which displays a correct weight value by averaging the digitized weight data outputted at predetermined time intervals from a weight detector provided in the balance. The weight data averaging to give a correct value is carried out with the number of the basis data for averaging increased each time a new weight data is obtained, after the weight data, which are largely fluctuating in the beginning, have been considered to be stabilized by being settled down in a predetermined limit. In case the once stabilized weight data are brought back into a fluctuating state owing to any external disturbance, such fluctuation is detected and the again unstabilized weight data are excluded from the averaging to give a correct weight value.
