WEIGHT SIGNAL COMPENSATION DEVICE IN WEIGHING APPARATUS

摘要

PROBLEM TO BE SOLVED: To compensate the drift of a weight signal generated in a weighing apparatus just after the electric power is turned on.

SOLUTION: A CPU 24 identifies a transfer function such that the weighing apparatus outputs when a signal referring to the signal approximately equal to a signal transition process caused by the weighing system of the weighing apparatus approaching from power on to a final value is inputted, and creates a correction signal corresponding to a calculated value for a time response output during the operation time of the weighing apparatus. The CPU 24 compensates the temperature deviation of the weight signal by making a correction signal act to the weight signal of the weighing apparatus during the operation time.
