Operation method of roller scale, involves correcting weighing curve of weighing signal by comparison with reference curve of rotary position-dependent reference signal, after correcting scale imbalance
摘要
<p>The roller scale track (11) is comprised of a load cell (17), and a measuring roller (13) that is supported on the load cell as a driver roller. The scale imbalance is corrected by determining the reference curve of the rotary position-dependent reference signal and the weighing curve of weighing signal corresponding to the rotary position-dependent placement of to-be-measured sample. The weighing curve of weighing signal is corrected by comparison with the reference curve of rotary position-dependent reference signal. An independent claim is included for roller scale.</p>
