Programmable linearization function
User can set output compensation
against the input using 14
compensation points, (X
1
, Y
1
), (X
2
,
Y
2
)…(X
14
, Y
14
). Each compensation
value between (Xn, Yn) and (Xn+1,
Yn+1) is connected by first order
approximate formula.
This linearization function is useful to
compensate the tank figure in level
measurement application and the flow
rate of steam or gas in flow measure-
ment application .
Functions for LINEARIZE are
available for FXW Version 6.0 and
upward.
By pressing INC at display of 2 , the
display is shifted to the setting of LIN-
EARIZE POINT 3 . Press CHNG at
display of 3 and input POINT XX to
be compensated. Then press ENT and
the display will be shifted to 5 .
Press INC at display of 5 and the dis-
play will be shifted to y for selection of
<1> Lin. point: LP and <2> Comp.
value : CV.
Select <1> Lin. point: LP at display of
6 and input XXX.XX% to each point
(LP1-LP ).
At the completion of input to all the
compensated points, press ENT twice
and the write of LP will be finished.
At this time, the display is shifted to 6 .
Select <2> Comp. point: CV at display
of 6 and input XXX. XX% to each
point (CV1-CV ) in the same manner
as noted in <1> LP. At the completion
of input to all the compensated points,
press ENT twice and the write of CV
will be finished.
At the completion of write of compen-
sated program for LP/CV, press CL
twice at the display of 6 for shifting to
2 . Then, press CHNG for selection of
<1> INVALID and <2> EFFECTIVE
of 19 . At display of 19 , press <2>
and the display will be changed to
EFFECTIVE.

Note) In the key stroke for Linearization, please set
each parameter in the below sequence.
1. Set the number of compensation points in the
range of 2 to 14.
2. Set each linearization option point (LP*) correctly,
and write them.
3. Set each compensation value (CV*) correctly, and
write them.
4. Set linearization option into EFFECTIVE and
write.
