Starrett Spring Testing Solutions

S tarrett S2 software is ideal for compression and extension. Springs are available withan outside diameter of 8 inches (200 mm), load rates of 1100lbf (5 kN) and travel lengths of 40 inches (1016 mm). The software lets you determine the following: • Load at Height/Length Limits (One or Two Points) • Load at Height/Length Limits (Multiple Points with optional Test Builder) • Height/Length at Load Limits (One or Two Points) • Height/Length at Load Limits (Multiple Points with optional Test Builder) • Free Length/Height • Spring Rate, Spring Constant, Initial Tension H igh - volume P roduction T esting with the S tarrett S2 S ystem

S2 software can operate on any Windows computer, including tablet computers, laptop computers or all-in-one workstations.

You can also compress to a load set and hold for a duration. • Single or dual limit tests may be used. You may specify a target load or target height/length to determine spring rate, spring constant, load and length at target limits, initial tension and measured free length. • The Data View displays the measured results. The spring constant is displayed for a single point test while the spring rate is displayed when using a dual point test method. • You may graph the test including the ability to witness the load at length/height or load at time profiles. Using the “overlay” function, you can map individual test graphs and overlay them onto one another to get a visual of individual test relationships. • The Summary View lets you compare all tests within a batch. You can establish tolerances for your springs and display “pass/fail” and tolerance relationships. • The Statistics View displays key statistical information for your batch including mean, range, standard deviations and tolerance results. • Perform more sophisticated, multi-stage testing when you use the optional Test Builder software. You can convert from a Spring Test template to the Test Builder quickly and easily.
