If the set pulse range is exceeded the value remains at the upper end of the range (higher
pulse numbers are ignored). Below the measuring range the signal goes to approx. 0 - 7 digit.

Make sure that the selected measuring range is not exceeded, otherwise speed changes in
excess of this will no longer be detected.
