tion

Evaluation with measured value window (pH) [New/[Properties] Mea-

sured 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 pH

Lower limit for the measured value window.

Input range

-20.000 - 20.000

Default value

-20.000

Upper limit pH

Upper limit for the measured value window.

Input range

-20.000 - 20.000

Default value

20.000

EP criterion

Criterion for the recognition of endpoints. Endpoints whose discovered
ERC value is smaller than the value entered here will not be recognized.
