<P>PROBLEM TO BE SOLVED: To provide a weighing device which easily and precisely identifies which load cell has an abnormal span during usual weighing operation, and which easily makes it return to a normal state. <P>SOLUTION: A weighing device includes half bridge load signal calculating means for arithmetically processing an applied load to load cells in such a manner that each of load signals Wa1, Wa2 output from two terminals becomes the load signals with the same magnitude. A load cell having an abnormal span is detected among the load cells by comparing the two half bridge load signals. <P>COPYRIGHT: (C)2012,JPO&INPIT |
