8.1.4 - Linearization menu
The IM-111 provides linearization for the input and/or the retransmitted signal. The
linearization is based on line segments defined by up to 20 points.

-9999 to 30000
Input signal (process variable) linearization.
May be set between engineering unit minimum and maximum (see
section 7.1.1,

-9999 to 30000 Output signal linearization in engineering units.
When the user selects the
.
or
.
parameters (Output menu
.
submenu)
, it is possible to define a customized linearization cycle. The input signal can be divided in 20
segments, so as to minimize the error between the input signal and the corresponding indication.
The
.
parameter corresponds to the start point of the first segment, which must match the
input signal minimum value. Next,
.
is the starting point of the second segment and so forth
until the
.
parameter, which corresponds to the last segment. Next,
.
corresponds to
the required indication for the first output point. Then,
.
is the required indication for the
second point and so forth until
.
.
.
must be defined as
.
. If all 20 linearization
points are not needed, the last used linearization point must be defined as
.
.
The upper and lower indication limits must be defined before the linearization settings.
