CUSTOM LINEARIZATION
I.MAIN
R W
The parameter sets linearization for the selected sensor type.
The function corrects any linearity and proportionality errors in the correlation between measured value and the actual
value.

This correction can be made with two different algorithms: 32-step linearization and 4-point linearization. Values are set (33 linearization
for 32 steps and 4 for 4-point linearization) with the LINRZ submenu parameters.
For an explanation of 4-point linearization, see paragraph “5.4. 4-point input correction ”5.2. 4-point input correction” on page 73.

R W
The parameter shows and sets the engineering units displayed for input 1. The unit appears on the Home page of the
display.
For thermocouple or RTD inputs, the °C / °F selection automatically converts the temperature value; the related scale
limits and setpoint limits must be set.
