7.7 Linearising sensors

Non-linear sensors can be linearised with up to 30 interpolation points per measuring
input.
At each interpolation point, the input signal is manually assigned a new display value.

The analogue output is also linearised since it is proportional to the display values.
Each interpolation point must have a higher input signal than the previous. The corre-
sponding display values can be freely assigned.
PN Function
100 Number of interpolation points
101 ... 130 Display value for interpolation point
Procedure
1. Set the number of interpolation points under PN 100/PN 140.
2. Apply the input signal for the first interpolation point, PN 101/PN 141, at the
measuring input.
3. Set the desired display value under PN 101/PN 141.
⇒
Input signal is associated with display value.
4. Repeat steps 2 + 3 for all interpolation points.
⇒
Input signal is linearised.
