BALANCE, WEIGHING APPARATUS AND METHODS FOR MEASURING AND AUTHENTICATING MASS

摘要

The invention relates to the determination of the authenticity of a weight signal. It relates to a method in which the output signal provided by a transducer 41 mounted on a flexible support 26 a swash plate 28 on which is firmly held a mail item 65, before being used to determine the weight of the mail piece, undergoes a determination of authenticity. This includes determining the uniformity of the alternating transducer output signal or comparing the decay rate of the signal amplitude with a reference speed. / P P Application to automatic weighing of the signal mail. / P
