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 vol-
ume axis or on the time axis. The break-point evaluation will only be car-
ried out in the defined window. Only the first break-point in the defined
window will be recognized.
Selection Measured value | Volume | Time | off
Default value off
Lower limit
Value for the lower limit of the window.
Window = Measured value
Range
-20.000 ... 20.000 pH
Default value -20.000 pH
Window = Volume
Range
0.00000 ... 9999.99 mL
Default value 0.00000 mL
