Scaling end values with data format VZ + 15 bits
linear scaled"
The following diagram shows an example of the data format
VZ + 15 bits linear scaled" with the scaling end values:
Lower limit = 400
Upper limit = 2000
With these values the output signal corresponds to e.g. for
the signal range 4...20 mA the digital output value multiplied
by 0.01 mA.
