Linearisation Tables
(Main Menu > Configure > Setup > Edit Setup> Field I/O > Linearisation)
Linearisation Tables - To be used with Analogue Input type Volts, Amps or Ohms.
These are user defined tables that can be set up to allow a non-linear input signal to be dis-
played on the recorder. By entering a set of non-linear signal input values (X) into the line-
arisation table, the recorder will use the table to generate linear output (Y) in engineering
units, to be displayed and/or log on the recorder.
• Select the next available table and rename it for ease of identification by selecting the
name button.
• Select the Values button to take you to the start of a new table. Press the Add button to
produce the first line. More than one set of points are required to do the conversion.
• Click into the text entry boxes under the X and Y boxes and enter the required values
(or leave it if your table starts at 0). The Signal Input (X) goes in the first column and the
Engineering units (Y) in the second column.
• To add a line at the bottom, click on Add. To ad a line above or below, click on a line and
use the Insert Above and Insert Below buttons. To delete a line, click in the line and
select Delete.
• When you have finished your tableselect the tick box, this will also verify the table and
produce a Data Error box if there are any problems..
Data Error box
If incorrect vales are entereed a Data Error box will appear saying “Data line * is invalid”. This will ap-
pear when you select the tick box at the bottom of the screen. The error box will indicate which line
has the error. There may be more than one error in the table, if so the data error message box will
appear for each error starting from the top line down going to the next as each error is fixed.
