ascending
Only endpoints with a positive slope of the titration curve will be recog-
nized.
descending
Only endpoints with a negative slope of the titration curve will be rec-
ognized.

window #
Volume windows are defined sub-regions (windows) on the volume axis for
which different parameters for the potentiometric evaluation can be
defined. Only those endpoints which lie within these windows and addi-
tionally meet the parameters defined for each window will be recognized.
Only one endpoint will be recognized per window.
Lower limit
Lower limit for the volume window.
