4.9.5. LIN - Selecting linearization type
Acronym Scrolling message Submenu Attributes
Lin INPUT.1 (or INPUT.2 or INPUT.3) CUSTOM LINEARIZATION INPUT R W
The parameter sets linearization for the selected sensor type.
The function corrects any linearity and proportionality errors in the correlation between the value sent by the input and
the actual value of the physical quantity measured..
ideal
correlation
correlation of
input
This correction can be made with two different algorithms: 32-step linearization and 4-point linearization. Values are set (33 for 32-step
linearization and 4 for 4-point linearization) with the LINRZ submenu parameters.Z and LIN.4.P. submenu .
For an explanation of 4-point linearization, see paragraph “5.4. 4-point input correction” on page <?>.
Unit of measurement: -
Options: NONE = No linearization
32.STP = 32-step linearization
4.POIN = 4-point linearization
4.9.6. UNIT - Selecting the displayed unit of measurement
Acronym Scrolling message Submenu Attributes
Unit INPUT.1 (or INPUT.2 or INPUT.3) UNIT OF MEASURE INPUT R W
The parameter shows and sets the unit of measurement displayed for input in use. The unit appears on the Home.x page
of the display.
For thermocouple or resistance thermometer inputs, the °C / °F selection automatically converts the temperature value;
the related scale limits and setpoint limits must be set.
Unit of measurement: -
Options: NONE = No unit of measurement
°C = Degrees Celsius
°F = Degrees Fahrenheit
CUST = Custom, settable with GF_eXpress
4.9.7. FILT - Digital filter
Acronym Scrolling message Submenu Attributes
FILT INPUT.1 (or INPUT.2 DIGITAL FILTER INPUT R W
The parameter shows and sets the value of the digital filter time constant.
With 0.00 no filter is applied.
Unit of measurement: Seconds
Options: 0.00...20.00
