4.1.3 Linearity Calibration
Linearity calibration utilizes three calibration points; one at zero, center span and full span. This method minimizes
deviation between actual and displayed weights within the Indicator's weighing range. Three weight values are used;
zero, a weight value at or near midpoint of the Indicator's weighing range and a weight value at specified capacity.
Sample display illustrates a 40 kg scale base.
