If this function is activated and Q
determined and stored.
If Q is low (-U ), the maximum value is transmitted at the analogue output.

Example of use: determining the maximum value of a shaft.
The minimum value can be determined by inverting the output characteristics (see func-
tion no. 16 and 17).
