7.5. Digital linearization

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 entered in, the calibrated data will

be refreshed using zero point and final input point data. There is no need to calibrate
again.
