Evaluation with volume window (mL)
This option is visible only for Titrando and 855.. With this option up
to 9 regions (windows) can be defined on the volume axis. Only those
equivalence points which lie within these windows and additionally
meet the parameters defined for each window will be recognized. Only
one EP will be recognized per window. The defined windows with their
parameters are shown in the window table and can be edited with the
following buttons:
Evaluation without window
EP criterion
Criterion for the recognition of equivalence points which is valid for all
windows. Equivalence points whose ERC is smaller than the set EP crite-
rion will not be recognized.
Input range 1 - 999 mV
Default value 30 mV
EP recognition
Filter for the recognition of equivalence points:
Titrino

all | greatest | last | ascending | descending |
off
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 to be found 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
Equivalence point recognition is switched off.
