Threshold value
0.5 ... [ 5.0 ] ... 10.0 (mS/cm)/s
The evaluation of the minimum begins as soon as the slope of the curve
exceeds the threshold value.
Maximum evaluation
on, [ off ]
For the maximum measured value the associated time and temperature are
interpolated from the list of measuring points) (see Titration commands -
Evaluation - Minimum/Maximum evaluation).
Threshold value
0.5 ... [ 5.0 ] ... 10.0 (mS/cm)/s
The evaluation of the maximum begins as soon as the slope of the curve
exceeds the threshold value.
Break point evaluation
on, [ off ]
A break point evaluation is used to determine sharp changes of direction in
the titration curve) (see Titration commands - Evaluation - Break point
evaluation).
EP criterion
0 ... [ 0.3 ] ... 1.0
Measure for the minimum sharpness of the break. The smaller the EP crite-
rion set, the more break points will be found. As this is a relative value re-
lated to the total measured value alteration, for a small measured value
range even small changes in the measured value can be evaluated as a
break point.
Slope
0.0 ... [ 0.9 ] ... 10.0
Minimum difference between the slope before and after the break point.
The smaller the difference, the more break points will be found.
Smoothing factor
2 ... [ 5 ] ... 20
The higher the smoothing factor, the fewer break points will be found.
Window
Measured value, Time, [ off ]
A range (window) can be defined on the measured value axis or on the time
axis. The break point evaluation will only be carried out in the defined win-
dow. Only the first break point in the defined window will be recognized.
Lower limit
[ 0.0000 ] ... 2'000.0 mS/cm (for Window = Measured value )
Measured value for the lower limit of the window.
[ 0 ] ... 999'999 s (for Window = Time )
Time for the lower limit of the window.
Upper limit
0.0000 ... [ 2'000.0 ] mS/cm (for Window = Measured value )
Measured value for the upper limit of the window.
0 ... [ 999'999] s (for Window = Time )
Time for the upper limit of the window.
