No. lin points → X/Y coordinates
The device has two linearization tables, each with a maximum of 32 linearization points. They are permanently
assigned to the ‘Calc value 1’ and ‘Calc value 2’ channels. If linearization is selected as the calculation, the
number of linearization points needed is specified in the ‘No. lin points’ parameter. An X-coordinate and a Y-
coordinate has to be specified for each linearization point. The linearization tables can be deactivated
individually.
