3.4.4 Peak & Valley Coefficients The Peak & Valley coefficients are used with applications that exhibit a cyclic graph form, such as those found in peel and adhesive testing. The Peak & Valley measurements include finding the maximum peak or the minimum valley; the average of selected peaks/valleys; our just simply finding the number of peaks or valleys based on load sensitivity. When Peak results are required, you will select above the graph curve. Selecting below the graph curve will deliver valley results. Sensitivity is used to specify the region that defined a peak or valley. Sensitivity is associated with the load data and is represented as a percent value of the load data for the graph. Sensitivity is a percent of the load where the measured load data on either side of the peak or valley are equal to or less than the Sensitivity setpoint. If the Sensitivity = 10, the data stream within the scope range is analyzed and the peak or valley is identified where the load on the incline side of the peak was 10 and the opposite side of the peak was also 10. If the incline side was 10 and the decline side was 9, the data segment would not qualify as a peak or a valley.
Sensitivity is used to evaluate a graph curve and identify the data points within the data stream that increase and decrease at the sensitivity value you are using or at a value greater than the specified sensitivity. NOTE
Load Sensitivity is used to define what qualifies as a peak or a valley. The two sides of the peak or valley must be equal to or less than the Sensitivity setpoint.
