In a window comparator the three signals will be generated from the measuring signal. The signal
"0-sheet" is generated when the measuring signal falls short of the lower switching threshold TL.
The lower switching threshold TL can be set from 1...99%. The signal "2-sheet" is generated when
the upper switching threshold is exceeded. The upper switching threshold TU can be set from
100...180%. If the measuring value is within both limits, the signal "1-sheet" is generated.

Fig. 10: Visualization of switching thresholds
The switching thresholds should be adjusted corresponding to the application.
"Nom./curr. settling time"
Defines the time which the system requires to reach stable measurement results.
For details refer to chapter 3.7.2.
