4.6 Performing a Test Run Once a test setup is launched, you may then proceed to perform a test run. A test run is an actual test of a single sample. Once a run is performed it is registered in the Runs List for that test setup and it is saved to the Metlogix/Runs directory. Test runs are listed numerically. Every test run has a unique test number. If a test run is deleted, the sequence of the test runs in the Runs List is maintained. For example, if you delete run #3 after performing five (5) runs, the Runs List will display 1,2,4,5. Run #3 is forever removed from the Runs List. This ensures that anyone looking at the Runs List can see that a run was deleted. Runs that ended due to an exception event, when the Omit Exception function is Yes (Pre Test), will appear in red text with a strike-thru. Runs that make use of a tolerance, and that contain a result that is out-
4.6.1 Pre-Run Procedure The following represent some common “pre-run” checks that should be done prior to performing a test run: • Start/Stop push button should display green. • The sample is secure and axially aligned in the test fixture. • Test fixtures are properly secured with tightened locking rings and Starrett grip pins. • The correct test setup is open and ready to be used. • The load cell sensor is communicating and displaying its full scale capacity beneath the load cell status icon. • The tester is configured for the proper test mode, e.g. normal mode or height mode depending on the test setup. • The H target is displayed when height mode is used • The D target is used when normal mode is used. • The correct units of measure are displayed for Load and Distance. • The correct graph options are displayed for the type of testing to be performed, e.g. load-distance. • If a splinter shield is used, the door on the shield is completely closed so that the interlock is enabled. • Travel limits are set to prevent over-travel conditions that can lead to a load cell overload condition. • Access to the Emergency stop is easily and quickly accessible to the user. • Access to the power switch to the frame, located on the back panel, is easily and quickly accessible to the user. WARNING Operating the system carelessly could result in serious injury or death. Keep hands, head and all other body parts away from the testing space when the crosshead is in motion. WARNING Moving parts can produce dangerous forces corresponding to the system capacity. All operators should read the instruction manual thoroughly to ensure they operate the system correctly. Control access to the system to ensure only trained operators operate the system. WARNING Keep the face and body away from the test specimen during tests. When the specimen breaks, flying debris could injure eyes or other body parts. Always use a safety guard or other measure to provide protection from broken specimens.
of-tolerance will appear in red text. All other runs will appear in black text.
When a Batch Name is used, the Batch Name will appear atop the Runs Number in the Runs List. A Batch Name may be setup in the Pre Test section of your test setup. When multiple runs are displayed together, a color-coded dot appears next to the run. This color designates the graph trace when multiple traces are displayed together. The active trace always appears with a black trace. When you use the split view with graph and data together, the black color identifies the test run that the data belongs to.
