10-segmentLinearizerBias
This function is used to correct an input signal affected by sensor deterioration. The
corrected values are obtained by adding the corresponding bias values to each of the 11
points of optionally set input values.
When10-segmentlinearizer
inputisA1orless,B1istobeadded.When10-segment
linearizerinputisA11ormore,B11istobeadded.

10-segmentLinearizerApproximation
This function is used when the input signal and the required measurement signal have a
non-linear relationship, for example, when trying to obtain the volume from a sphere tank
level. As shown in the figure below, the output values can be optionally set to 11 points of
the optionally set input values.
Whenthe10-segment
linearizerinputisA1orless,thevalueofextendedlinebetween
B1 and B2 is output. Moreover, when the input is A11 or more, the value of extended line
between B10 and B11 is output.
