5.6.3.3.2.9 MET pH - Measured value window
Dialog window: Method ▶ MET pH ▶ Properties... ▶ Potentiometric evalua-
tion ▶ Evaluation with measured value window (pH) ▶ [New]/[Proper-
ties] ▶ Measured value window#
Measured value windows are regions on the measured value axis for which
different parameters for potentiometric evaluation can be defined. Only
those endpoints which lie within these windows and additionally meet the
parameters defined for each window will be recognized. Only one endpoint
will be recognized per window.
Lower limit pH
Lower limit for the measured value window.
Range -20.000 ... 20.000
Default value -20.000
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.
