8. Examples

8.1 Temperature measurement

A temperature sensor with linear characte-
ristics (in case of non-linear sensors, install
linearizing components upstream) delivers 0 V
at -10°C and 10 V at 80°C. The selected mea-
suring range is 0 ... 10 V. 0 V is the smallest
measured value possible. The display value
-10 is now assigned to this measured value.
Accordingly, 10 V is the largest measured
value. The display value 80 is assigned to this
measured value. The display is now set for the
sensor and can display any intermediate value.
Display value freely positionable
