4.5.3. Lin - Linearization type
Acronym Scrolling message Submenu Attributes
Lin 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.
Correlation
of input
Ideal
correlation
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.
Unit of measurement: -
Options: NONE = No linearization
32.STP = 32-step linearization
4.POIN = 4-point linearization
4.5.4. Unit - Displayed engineering units
Acronym Scrolling message Submenu Attributes
Unit ENGINEERING UNITS I.MAIN 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.
Unit of measurement: -
Options: NONE = No unit of measurement
°C = Degrees Celsius
°F = Degrees Fahrenheit
CUST = Custom, settable with GF_eXpress
4.5.5. FILT - Digital filter
Acronym Scrolling message Submenu Attributes
FILT DIGITAL FILTER I.MAIN 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
