Threshold value
The evaluation of the minimum begins as soon as the slope of the curve
exceeds the set threshold value.
Range
0.1 ... 20.0 pH/mL
Default value
1.0 pH/mL
Break-point evaluation
Note
This evaluation method is possible only with Titrando and 855.
Break-point evaluation
on | off (Default value: off)
A break-point evaluation is used to determine sharp changes of direction in
the titration curve.
EP criterion
Measure of the minimum sharpness of the break-point. The smaller the EP
criterion set, the more break-points will be found. As this is a relative value
related to the total measured value alteration, even small changes in the
measured value can be evaluated as a break-point for a small measured value
range.
Range
0 ... 1.0
Default value
0.3
Slope
Minimum difference between the slope before and after the break-point.
The smaller the difference, the more break-points will be found.
Range
0.0 ... 10.0
Default value
0.9
Smoothing factor
The higher the smoothing factor, the fewer break-points will be found.
Range
2 ... 20
Default value
5
Window
A range (window) can be defined on the measured value axis, on the volume
axis or on the time axis. The break-point evaluation will only be carried out
