6.1.3 Setting Grip Protection The Lx Series software lets you add load limits on your testing fixture to help minimize potential damage to the test fixture due to overload- ing. NOTE In many applications, the weakest component is the test fixture, having a load capacity rating that is less than the load cell sensor being used. Grip protection helps ensure that the test fixture is protected from accidental overloading, which can permanently damage the fixture. NOTE Sudden shock loads to the test fixture may not protect the test fixture from damage even when Grip Protection is used. Shock loads can occur when operating at high velocity.
You can help minimize test fixture damage by setting Grip Protection as the maximum load allowed for your load string as follows:
1. With your Lx Series software, access the Main Settings menu by selecting the Lx symbol.
2. Select the Settings symbol. 3. Select the Loads setting.
4. Set the Grip load to a load value that is less than the test fixture’s rated maximum load capacity. Starrett recommends a Grip Load value of 10% less than the rated capacity. If your test fixture has a rated full scale capacity of 1000N, we recommend you set your Grip load at 900N. 5. Select Done.
Set Grip Protection as follows:
1. Select L3 Symbol for Main Settings Menu 2. Select LOADS setting 3. Enter value for the maximum load based on the full scale load capacity of the test fixture/grip being used. 4. Select DONE
