Abstract
A method to automatically calibrate a load cell without the need to remove the loading on the load cell. This method takes advantage of the fact that weight stack strength equipment uses generally known discrete weight increments, and any signal drift in the load cell can be automatically recalibrated by offsetting the load cell signal to accurately reflect the expected discrete weight increments without the need for unloading the load cell and without the need for a manual recalibration of the load cells.
