Upper limit pH
Upper limit for the measured value window.
Range -20.000 ... 20.000
Default value 20.000
EP criterion pH
Criterion for the recognition of endpoints. Endpoints whose discovered
ERC value is smaller than the value entered here will not be recognized.
Titrando, 855
Range
0.1 ... 9.99
Default value 0.50
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.
descending
Only endpoints with a negative slope of the titration curve will be rec-
ognized.
5.6.3.3.2.10 MET pH - Volume window
Dialog window: Method ▶ MET pH ▶ Properties... ▶ Potentiometric evalua-
tion ▶ Evaluation with volume window (mL) ▶ [New]/[Properties] ▶ Volume win-
dow #
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.
