AUTOMATED TEST SYSTEM
Automated Test System (ATS) software for true Closed Loop Test Control with Windows (3.1 or '95)interface, context sensitive help, pop-up menus and customizable on-screen displays. Full report templates, transducer calibration routines and ATS Scope for optional dual-trace oscilloscope displays in X,Y or X-Y modes.
DYNAMIC-REPETITIVE-CREEP-RAMP-SEQUENCER-DATA-WAIT-LIMIT
Almost all standard mechanical asphalt and triaxial unbound material tests can be run with this software which can control up to 4 closed loop procedures.
Test Routines include:-
- AASHTO T294/SHRP P46 -AASHTO TP7/SHRP P005
- AASHTO TP10 - AASHTO TP0/SHRP M005 - ASTM D3497
- ASTM D4123/SHRP PO7/AASHTO TP31 - M009
- RSST-CH (TP/P005) - 2 Degree of freedom controller
- (Custom Test Modules can be implemented)
