Displaying linearization on a graphic ("Display graphic" button)
Use this button to create a graphic of the linearization.
The graphic includes the characteristic lines for both types of linearization where applicable, namely the
formula and the grid points (table).
The display range for the graphic is initially determined by the "measuring range start" and "measuring
range end" values (y values); it can be temporarily changed in the display by entering different x values.
9.11.2 Grid values
Customer-specific linearization is specified by entering up to 40 grid points (pairs of values X/Y). The
value of X stands for the physical measured value (e.g., voltage in mV, current in mA, or resistance in
ohm; depending on the sensor type) and the value of Y stands for the linearized value (e.g., temperature
in °C).
Setup dialog box
Parameter
The definition range of linearization (measured values, x axis) is monitored in the module and delimited
as follows:
Lower limit of the definition range = Xmin - 0.0125 × (Xmax - Xmin)
Upper limit of the definition range = Xmax + 0.03125 × (Xmax - Xmin)
Parameter Selection/settings Description
Measured value
(X)
-99999 ... 0 ... +99999 Value of the relevant grid point on the x
axis
Linearized value
(Y)
-99999 ... 0 ... +99999 Value of the relevant grid point on the y
axis
Always give a temperature value in °C.
