3.4.3 Modulus/Slope Coefficient Slope, also called Modulus in some industries, is used in load-distance applications in determining elastic or rate. The L3 Series software offers four methods for determining modulus/slope: • Slope Fit (Automatic) • Maximum Slope • Slope Tangent • Slope Two-Point (Segment Slope, Chord Slope, Secant Slope) Each of these are described in the following sections.

Slope Two-Point (Chord Modulus)
Finds the greatest slope using the Slope Fit algorithm at a scope starting at 0.037% strain and a finish at 0.140% strain. The elastic modulus is 287303.75 Mpa. The green line is the slope line. The blue section on the line represents the data used to find the greatest slope.
