N_RANGE (nominal range) is used to define the pressure range of the sensor. This
value should be always same as or higher than SYS_RANGE. The control parameter
cannot be calculated correctly in case of wrong values.

Adjustment of the zero point of the sensor. If the command signal and feedback signals
are not zeroed to each other this offset should be used.
Using of the commands SYS_RANGE, N_RANGE:X and OFFSET:X
Example of use:
With these commands, the feedback sensor is scaled. Suppose you have a pressure
control with the following characteristics:
The system pressure is 350 bar
The pressure sensor has a 4-20mA current output
The nominal pressure of the sensor is 600bar (20mA at 600bar)
The sensor has an offset of 3bar (at 0bar real pressure 3bar is displayed)
To scale this sensor correctly the following settings should be made:
SYS_RANGE 350 bar
SIGNAL:X
I4-20
N_RANGE:X 600 bar
OFFSET:X
-3000 mbar
