476 Method
Fixed quantity
[ Measured value ], Time
Selection of the fixed quantity to which the associated values for the other
quantities are to be interpolated from the list of measuring points.
Fix EP# at
-200.0 ... 200.0 µA, [ off ]
Fixed end point 1 ... 9 for Fixed quantity = Measured value .
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
0.5 ... [ 5.0 ] ... 10.0 µA/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 µA/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.
