8.8.2 Grip Load The Grip Load is a value that you enter to protect your test fixture (grip) from damage due to overloading or exceeding the load capacity of the test fixture. All test fixtures have a load capacity. This load capacity is the maximum load that the test fixture is rated to. Loads exceeding this capacity can permanent damage the test fixture. Often, the maximum capacity of the test fixture is below the maximum load capacity of the load cell sensor, therefore, the maximum load for a test setup should be the lowest rated capacity of the test fixture, load cell or test frame. The Grip Load setting allows you to enter a load capacity limit based on the testing fixture used. For example, you may have a 1000N load cell, but you are using a test fixture with a maximum testing capacity of 50N. In order to protect the test fixture, you can set the Grip Load to 50N. When 50N is reached, the test run will terminate and protect the test fixture. WARNING Excessive crosshead speed may make it impossible to stop in sufficient time to prevent an overload. Do not use high speeds, particularly in compression directions.
NOTE If Grip Load is set, a test run will abort if the measured load exceeds the Grip Load value you have entered. NOTE The Grip Load value is sign dependent. If your compression sign is negative, you must enter the Grip Load value as a negative value if you intend to protect your test fixture with a load capacity limit in the compressive direction. 8.8.3 Frame Capacity The Frame Capacity value is automatically displayed and represents the maximum allowed load capacity for the test frame your L2 Plus system is configured with. This is a “read-only” value and is not adjusted. NOTE No tests may be performed beyond the Frame capacity.
L2 Plus LOAD Setting Shows the frame capacity for this L2 System at 112lbf (500N)
L2 Plus LOAD Setting An exception stops aborts the test run when the Grip Load is exceeded
