Description
Use the UCW command to set and verify individual user calibration table records. New
records can only be entered if the Calibration table is cleared first (see Section 6.4.25)
Up to 64 records can be entered sequentially into the sensor’s RAM and verified. Once
sufficient records have been loaded, these can be saved to the Flash using the user
calibration save command (see Section 6.4.27).
