<p><P>PROBLEM TO BE SOLVED: To precisely detect a span fluctuation portion in which a zero-point fluctuation portion is excluded, in an output of two half bridge circuits of load cells for meters. <P>SOLUTION: The device comprises: two load signal calculation parts performing arithmetic processing in a way load signals Wa and Wb from two terminus are the same magnitude of load signals, for a burden load of load cells; and a display unit 54 displaying an absolute value of a difference in the two load signals or vales of the two load signals, output from the two load signal calculation parts. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
