Evaluation without window
With this option set, the two parameters EP criterion and EP recog-
nition will be applied across the entire range of the titration curve.
Evaluation with measured value window (pH)
With this option set up to 9 regions (windows) can be defined on the
measured value axis. Only those equivalence points which lie within these
windows and additionally meet the parameters defined for each window
will be recognized. Per window only one EP will be recognized. The
defined windows with their parameters are shown in the window table
and can be edited with the following buttons:
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 pH
Criterion for the recognition of equivalence points which is valid for all win-
dows. Equivalence points whose ERC is smaller than the set EP criterion will
not be recognized.
Range 0.10 ... 9.99
Default value 0.50
EP recognition
Filter for the recognition of equivalence points:
Titrino
Selection
all | greatest | last | off
Default value all
Titrando, 855
Selection
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 steepest
jump, will be recognized.
last
Only the last equivalence point to be found will be recognized.
