Linearization
Linearization must be selected to match the sensor (measuring probe).
The predefined linearizations can be supplemented with customer-specific linearization.
chapter 9.11 "Customized linearization", Page 226
Measuring range
For customer-specific linearization, the values are identical to the settings at that point for the "Measuring
range start" and "Measuring range end;" they cannot be changed here.
Scaling
In typical linearizations for RTD temperature probes and thermocouples, this parameter delimits the
measuring range.
Example: Pt100, scaling 0 to 200 °C
The physical measuring range of the hardware from -200 to +850 °C is delimited. Only measured values
in the range 0 to 200 °C are processed. The diagram and bar graph have a plottable range of 0 to 200 °C.
The values are covered by automatic °C/°F conversion.
For voltage and current signals the measured value is scaled, taking the measuring range into ac-
count.
Example: Input 0 to 20 mA; measuring range start 5 mA; measuring range end 18 mA; scaling: -500 to
+1000
From the measuring range 0 to 20 mA, only values in the range 5 to 18 mA are taken into account. The
value range 5 to 18 mA is scaled to the range -500 to +1000. 5 mA corresponds to -500, and 18 mA cor-
responds to +1000. The range -500 to +1000 is used for the diagram, bar graph, and all further process-
ing. The values are covered by the automatic °C/°F conversion if the measured value has been defined
as a temperature ("Temperature input" parameter).
For customer-specific linearization the values initially reflect the local settings for "Measuring range
start" and "Measuring range end;" the scaling range can be further delimited here.
