5.7.2 Minimum Algorithm (Peak) The Minimum algorithm finds the minimum or lowest measured result within a scope segment or for the entire test. Selecting above the curve will let you look for the minimum peak loads. Setting the sensitivity will define the peaks that qualify and based on these qualified peaks, the algorithm will find and report the peak having the minimum load or stress value for all of these peaks. 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. 5.7.2.1 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.
5.7.2.2 Minimum Algorithm Scope The scope for the Minimum 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. Minimum Algorithm Name The Minimum algorithm name may be changed from its default of Lpeak when based on load. For example, you may rename Lmin. 5.7.2.3
The result name may be up to 8 characters in length and may use special characters.
Sensitivity = 5%
The peak with the minimum load is identified with the bright blue line. Other qualified peaks (Sensitivity 5%) are also displayed in light blue.
Note, the name of the coefficient was changed to MinPk (minimum peak).
