WEIGHING SCALE WITH VALIDATING REFERENCE CHANNEL |
摘要 |
An electronic scale for weighing an article includes a weighing channel for providing an output indicative of the instantaneous weight of the article and a reference channel for providing an output indicative of instantaneous vibrations affecting the output of the weighing channel. The scale also has a mechanism for providing a signal indicative of a long term average of the reference channel's output. Another mechanism of the scale compares the average signal with the reference channel's output and provides a validation signal when the reference channel's output does not differ by more than a threshold amount from the average signal.
