4.6.1.1 Manual Zero The Pre Test section has an option called Set Home that will automatically zero the Load and Distance values when the Start Test target or Start push button is pressed to begin a test run. If the Set Home function is not used (Set Home = No), you must zero the Load and Distance values prior to starting the test run. • Press the L target to zero Load • Press the D target to zero Distance
4.6.1.2 Set Home The Home position is critical to successful testing. The Home position is defined as where the test starts from. It is the location used to set your sample into the testing fixture and the location where the software begins measuring load and distance values. When the Setup Home option in Pre Test is Yes, the Home position is established at the point where the Start Test target or Start push button is pressed. If the Set Home option is not used in Pre Test = No, the user must manually Set Home by pressing the Set Home target. Press Set Home after you have zeroed Load (L) and Distance (D).
