Table function (Linearization)
Depending on the application and according with the process, the transmitter output or PV is shown
in one linear characteristic curve (position, level, opening etc.). TP also has the option for adjust this
curve of linear output, to that the value in percentage can be linearized, you have to uses a table 16
points at maximum and minimum points 2. The output is calculated by interpolating these points.
The user can set the total of points desired.
To configure the feature table:

The user must choose the item "function" to "table" option.

Select the number of points, according to you need, 2-16 points.

Create the table and indicate the current position value in the "X" (%) column and the
desired position value in the "Y" (%) column. Once created the table, send the points for
the position transmitter.

Done, this configured.
