Measured value window (U)
Measured value windows are regions on the measured value axis for which differ-
ent parameters for the potentiometric evaluation can be defined. Only those
equivalence points which lie within these windows and additionally meet the pa-
rameters defined for each window will be recognized. Per window only one EP will
be recognized.
Lower limit
[ -2000.0 ] ... 2000.0 mV (Titrando)
[ -2000 ] ... 2000 mV (Titrino)
Lower limit for the measured value window.
Upper limit
-2000.0 ... [ 2000.0 ] mV (Titrando)
-2000 ... [ 2000 ] mV (Titrino)
Upper limit for the measured value window.
EP criterion
0 ... [ 5 ] ... 200
Criterion for the recognition of equivalence points. Equivalence points
whose ERC is smaller than the set EP criterion will not be recognized.
EP recognition
Filter for the recognition of equivalence points (only Titrando):
first
Only the first equivalence point to be found 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.
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.
