2.9 PR_CUST_LIN Block Parameter List
2.9.1 Linear interpolation linearisation, Description
LinType 1 = “Linearisation Table” generates a customer specific linear interpolation linearisation. Linear
interpolation linearisation can be used on mV, ohmic and potentiometer signals.The linear interpolation
linearisation is defined by straight lines drawn between the entered X / Y (input / output) coordinates.
The linearisation table must consist of 10 to 50 coordinate sets. The X values of the coordinates must
be entered in ascending order. The lowest and highest X values function as the lower and the upper lim-
it respectively. All X values must be entered as µV, Ohm or % for Voltage, Resistance or Potentiometer
measurements in that order. The table output will be converted to actual chosen PRMARY_VALUE_UNIT
(Example: 1000 / 3000 as X / Y values: output will read 3,00 if PRIMARY_VALUE_UNIT is set to “mV” and 1
mV is connected to input).
