SPAN ADJUSTING METHOD AND APPARATUS |
摘要 |
A span adjustment method includes applying a known load to a weighing machine and converting an output value from the weighing machine into a digital value by using an analog-to-digital converter. The characteristic of the analog-to-digital converter is sequentially varied automatically by a span adjustment value, which is produced as an output by a control unit, so that the digital value resulting from the analog-to-digital conversion becomes a digital value set in the control unit and conforming to the known load. |
