Fig. 4.5. Sampled signal levels.
Calculate Auto-limit: KPM KB2 calculates the web-on to web-off ratio (Paper-to-Break Ratio)
when both cases has been stored as references in memory.
KPM KB2 also suggests the best signal for break detection and puts them in a ranking list.
Normally the best signal is chosen for break detection by having it in display and pressing
right arrow and then "ENTER".
Then KPM KB2 sets the break trigger point ("Detection Limit") to 50 % of the difference
between the web-on and the break-on levels for the selected signal. The unit sets also
automatically the detection direction.
