Fix EP# at
0.0 ... 999'999.9 s, [ off ]
Fixed end point 1 ... 9 for Fixed quantity = Time .
The fixed end points Fix EP4...9 are displayed additionally to Fix EP1...3 by
pressing this button.
Only the fixed end points Fix EP1...3 are displayed by pressing this button.
Minimum evaluation
on, [ off ]
For the minimum measured value the associated time and temperature are
interpolated from the list of measuring points) (see Titration commands -
Evaluation - Minimum/Maximum evaluation).
Threshold value
1.0 ... [ 25.0 ] ... 2'000.0 mV/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
1.0 ... [ 25.0 ] ... 2'000.0 mV/s
The evaluation of the maximum begins as soon as the slope of the curve
exceeds the threshold value.
Break point evaluation
on, [ off ] (Titrando only)
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.
