6.2.2 Pausing an L3 Test Setup When an extensometer is used and recognized by your system, a sym- bol displays in the header tool bar showing an active extensometer and the instrument’s rated gauge length. When an extensometer is used, it allows the user to momentarily “pause” a test using the Start/Pause/ Stop push button or by utilizing the pause function within your L3 Series software. It is sometimes necessary to pause a test in order to remove an extensometer from a sample that is about to rupture/break in order to protect the extensometer from potential damage. To Pause an active test, press the Start/Pause/Stop push button until the LED displays a flashing RED indication. This indicates that the crosshead has stopped moving, but the test remains active. Pressing the Start push button restarts the run. NOTE When a run is paused, the run state is also displayed by the controller view. Selecting the Start symbol immediately starts the run. WARNING Never remove a sample while the sample is under load. When the Pause function is used, the sample may still be under load and should never be touched.
6.2 Using Lx Series Software Your MMD Series should be operated using either L3 Series software or L2 Plus Series software and an all-in-one computer workstation, or using L2 Series software with a tablet computer. Your MMD Series test frame features a Stop/Pause/Stop push button. This button features an LED indicator that indicates that crosshead status- whether or not the crosshead is active, moving or stopped. 6.2.1 Starting an L3 Test Setup Starrett recommends using the Start/Stop push button to start a test when using Lx Series software. Optionally, you may use the Start Test/ Stop Test target on the Lx Series controller view (See Lx Series soft- ware manual for detailed instruction on How to Perform Lx Testing).
NOTE The Pause function is not available in L2 or L2 Plus Series software.
