Outline Of The Linearization Function

Even if zero and span points have been calibrated, weighing errors may occur between the
zero point and weighing capacity. This is a corrective function designed to non-linearly correct
weighing errors.
It is possible to input up to four points in addition to the zero point.
The zero point and each input point will be corrected to put them in a straight line.
Areas between input points that could not be corrected completely with straight line
correction or with secondary correction will be corrected using a curved line derived from
high-order equations.
When the actual load input for digital linearization is performed, the calibrated data will be
refreshed using zero point and final input point data. It is not necessary to calibrate again.
