ReadWin 2000 operating software supports the generation of a tank linearization table.
Here you can find a tank linearization generator which you can use to generate the linearization
table for standard and customer-specific tanks.

M23..MXX
Displays the set value pairs of the linearization table. This menu item is only visible if a linearization
table was configured under Section 6.3.9 and "Yes" was selected in the "Show points" parameter in
the "LIN. TABLE/M21" menu.
