EP recognition

This parameter allows you to filter out only the equivalence points that are
being sought.

Selection

Default value

all

all
All equivalence points will be recognized.
greatest
Only the equivalence point with the greatest ERC value, i.e. the steep-
est jump, will be recognized.
last
Only the last equivalence point will be recognized.
ascending
Only equivalence points with a positive slope of the titration curve will
be recognized.
descending
Only equivalence points with a negative slope of the titration curve will
be recognized.
off
No evaluation takes place.

Set windows

This parameter allows to recognize equivalence points only in a particular
range (so-called window) of the curve. Equivalence points outside this
window will not be recognized. A maximum of 9 windows can be
defined. Setting windows is advisable when interference and unnecessary
equivalence points are to be suppressed.
