5.10 Using the Delta Tool The Delta tool is used to measure or compare the differences between two variables. These variables can be load or distance. The Delta tool is ideal for creep and relaxation testing or on applica- tions where you simply want to measure the change within a scope range. 5.10.1 Delta Algorithm The Delta algorithm measures the difference or change between two results. The scope segment may be the entire test duration or a seg- ment within the duration.
5.10.1.1 Delta Algorithm Scope The scope for the Delta 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.
The scope range is normally not at the start of the test since the mini- mum result would be zero or at the load when the test started.
Delta can be used to calculate the differences between two results.
Above, the Delta tool is used to calculate the difference between Lmax and Lmin and D@lmax and D@lmin.
