5.7.3 Maximum Algorithm (Valley) The Maximum algorithm finds the maximum or greatest measured result within a scope segment or for the entire test. Selecting below the curve will let you look for the maximum valley loads. Setting the sensitivity will define the valleys that qualify and based on these qualified peaks, the algorithm will find and report the valley having the maximum load value for all of these valleys. Sensitivity Sensitivity is a percent value. It is the percent that qualifies a peak or a valley based on an equal percentage rise and fall. For example a sen- sitivity of 5 would look at all data within a defined scope region where the data for a rise and fall is at least 5% of greater. When the portion of the curve qualified against the sensitivity, it is highlited in blue. 5.7.3.1 If a rise on the curve for load was 5% (an increase in load from the start of the rise to the end of the rise (peak), and the fall on the curve was less than 5%, this portion of the curve would not qualify, therefore, the segment on the curve is not a valid peak and valley. This portion of the curve would not highlight in blue.
5.7.3.2 Maximum Algorithm Scope The scope for the Maximum algorithm is based on two specific points that defined the end points of a data segment.
You may position the scope handles along either the y-axis or x-axis to define the data segment where you are interested in analyzing.
Or, you may implicitly specify your start and end scope points using values or other coefficients that can be used as anchors. Anchored coefficients display in yellow. Maximum Algorithm Name The Maximum algorithm name may be changed from its default of Lvalley when based on load. For example, you may rename Lmax. 5.7.3.3
The result name may be up to 8 characters in length and may use special characters.
All valleys that meet the Sensitivity > 5% are displayed in light blue for the specified scope range- Start to Finish @ 15mm. The bright blue valley represents the Maximum Valley, e.g. the valley with the greatest load value of the qualified valleys.
Sensitivity for valleys begins nearest the x-axis since you specify a valley measurement by selecting BELOW the graph trace.
