Abstract
PURPOSE: To calculate accurately the total weight without deteriorating manipulation by making corrections by using the mean value of a span change calculated from the integration value of error component, obtained by substracting constant momentary weight from the output of a load converter, and the number of work lengths of the load converter in a balance testing state.
CONSTITUTION: Balance testor 11 is enabled to load simulatively weight on load converter 5 of belt scale 2 for a constant moment and in its balance testing, error component obtained by subtracting this constant momentary weight from the output of load converter 5 is integrated by arithmetic unit 13 in sequence up to the end of the balance testing, thereby calculating the mean value of a span value by using the integration value, the rotational frequency of belt scale 2 and the number of work lengths of load converter 5. By the calculated mean value of the span change, the output of load converter 5 is corrected and the correction like this is automatically made on the stop of the supply from feeder 1, so that the manipulation will never deteriorate.
