defined. Setting windows is advisable when interference and unnecessary
equivalence points are to be suppressed.
Selection Measured value | Volume | off
Default value off
Measured value
The windows are defined on the measured value axis.
Volume
The windows are defined on the volume axis.
off
The entire titration curve is being evaluated.
Setting windows
The list of defined windows is opened with [Set window].
When the list is opened for the first time, a window over the entire mea-
sured value range or volume range is already defined. The windows must
not overlap, they only may lie next to one another. For each window, own
criteria can be defined for the equivalence point recognition.
NOTICE
When you define a result variable instead of a numerical value as limit
value (see chapter 32.6, page 496), then just one window can be
defined.
[New]
Define a new window. This is only possible when not the entire range is
covered yet.
[Delete]
Delete the selected window.
[Edit]
Edit the settings of the selected window.
Lower limit
Measured value or volume for the lower limit.
The values that are actually measurable may vary from the values specified
here, depending on the hardware. The binding measurement value ranges
can be found in the "Technical specifications" chapter for the control
instrument used.
Measured value (measuring mode pH):
Input range –20.000 to 20.000
Default value –20.000
