5.6.3.2.5.9 DET Upol - Measured value window
Dialog window: Method ▶ DET Upol ▶ Properties... ▶ Potentiometric evalua-
tion ▶ Evaluation with measured value window (Upol) ▶ [New/[Proper-
ties] ▶ Measured value window #
Measured value windows are regions (windows) on the measured value
axis for which different parameters for 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 measured value window.
Input range -200.0 - 200.0 µA
Default value -200.0 µA
Upper limit
Upper limit for the measured value window.
Input range -200.0 - 200.0 µA
Default value 200.0 µA
EP criterion
Criterion for the recognition of equivalence points. Equivalence points
whose ERC is smaller than the set EP criterion will not be recognized.
Input range 0 - 200
Default value 5
EP recognition
Filter for the recognition of equivalence points:
Titrando, 855
Selection
first | greatest | last | ascending | descending
Default value first
first
Only the first endpoint to be found will be recognized.
greatest
Only the endpoint with the greatest ERC value, i.e. the steepest jump,
will be recognized.
last
Only the last endpoint to be found will be recognized.
ascending
Only endpoints with a positive slope of the titration curve will be rec-
ognized.
