(3) Setting 10-segment Linearizer
Description
A total of up to four 10-segment linearizers can be used for the input unit and output unit.
For the position used by a ten-segment linearizer, see the function block diagram.

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.
