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 = 0
Upper limit = 6000
The example shows a sensor which converts the range of the
physical measuring variables from 0...6 bar linear into the
analogue signals 0...10 V or 0...20 mA.
