LCF Application Software

AC-08-0003 LCF application is intended to perform Low Cycle Fatigue test (as per ASTM E606) under MTL-7 environment with 2350/2360/2370 controller. The user interface includes specimen description, loading parameters, pump controls, test run/stop, graph display, numeric readouts of several relevant test parameters. Test descriptions and test settings are available as panels accessed by clicking on relevant tabs or pull down menu
