8.5 Line compensation
Line compensation is necessary when using the Pt100 with a 2-wire input.
The trimming is performed by numerical preset of the measured line resistance. The line
resistance is the combined total of sending and return conductors.
8.6 Type of characteristic curve (rising or falling)
The type of the characteristic curve at the 4 to 20 mA analog output can be selected (rising
or falling). The characteristic curve type is defined as follows by setting the parameters for
the start of scale value and full scale value:
● Rising characteristic: Full scale value is greater than start of scale value.
● Falling characteristic: Full scale value is less than start of scale value.
