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.
