Min./Max./Area Tab
Use this tab to define the evaluation of the minimum and maximum values
contained in the curve and to define the calculation of the area under the kinetic
curve.
The Min./Max./Area tab contains the following elements:
Input data
drop down list
Select the input data to be processed.
Mean minimum
value check box
Select to open the Points text field where the fixed
number of points has to be entered for the minimum
value. An even curve will then be generated using these
points and the lowest value contained in the curve
determined.
Mean maximum
value check box
Select to open the Points text field where the fixed
number of points must be entered for the maximum
value. An even curve will then be generated using these
points and the highest value contained in the curve
determined.
Area check box
The start and end time can be typed into the provided
text fields, otherwise the whole kinetic is analyzed.
• Time/Points option buttons:
If Time is selected the start and end time is entered in
hours, minutes and seconds. If Points is selected the
start and end point for the analysis is given through
the entered kinetic cycle number.
• Start field:
The start time (in hours, minutes and seconds) or
cycle number has to be entered here.
• End field:
The end time (in hours, minutes and seconds) or cycle
number has to be entered here.
Averages are taken from the number of points starting from the first kinetic
measurement value and stepping through one by one until the last kinetic
measurement point is included in the average calculation. The
minimum/maximum value is determined from these averages.
The result data made available through this method includes minimum/maximum
value, and the time span from the first measurement to the minimum/maximum
value in seconds.
Example:
With a kinetic of 5 cycles and a fixed number of 3 points, following averages are
taken:
st
nd
rd
nd
rd
th
rd
th
th
average of 1 , 2 , and 3 kinetic value
average of 2 , 3 , and 4 kinetic value
average of 3 , 4 , and 5 kinetic value
The minimum/maximum value is determined from these 3 averages.
The area under the curve is calculated using the formula given below:
n −1
A = ∑ y i * ( xi +1 − xi ) +
i =1
