Visit www.ppiindia.net for technical notes on USER LINEARISATION for detailed understanding of the parameters /
terminologies used for describing the parameters in this section.
The parameters listed on this page are used to implement the linearisation curve on the process value represented by the DC
linear output of a transmitter. The parameters affect the measured PV only if the ‘User Linearisation’ feature is ‘Enabled’ and if
the input type is DC Linear. That is, the PV measured using Thermocouple or RTD is not affected by the linearisation
parameters. The Table 8.1 below lists the user linearisation parameters.
