Abstract
Method for tracking creep and drift of a digital scale after a load has been placed upon a scale pan. The tare weight is determined at a time before a load is placed upon the pan and is stored. After the pan comes to equilibrium, the gross weight of the scale is determined and stored. Variance in the gross weight as a result of creep and drift is tracked and after an incremental amount is determined the value of such variance is added to the stored tare weight so that upon removal of the load from the pan the true tare weight is maintained.
