L1 T est T emplates The L1 System includes a set of common force measurement test templates. The templates have a common format consisting of these four test setup stages.
• Pre Test • Test • Data • Post Test
T est S etup A rchitecture All test setups include four common, easy-to-understand, menu- guided stages: Pre Test, Test, Data and Post Test.
D ata S tage The Data stage is where you specify what results you want. For example, you can select Maximum Load, Distance @ Maximum Load, Distance @ Load Limit, Load @ Distance Limit and more. A list of values is displayed and you simply select the result you want. The Data stage is also where you can utilize tolerance limits for immediate "Pass/Fail" identification.
P re T est S tage The Pre Test stage supplies options you would perform prior to testing, for example, specifying the units needed to measure load and distance.
T est S tage The Test stage is where you specify your testing requirements- what load you are using, what distance your crosshead will move, how fast your test speed is. Plus, you can easily add "exceptions". Exceptions are events that can be used to automatically stop your test, if they occur.
P ost T est S tage The Post Test stage lets you define what you want to do when the test concludes. You can export raw data or just the results and send to a network server. You can easily export directly to Microsoft ® Excel ® for custom report generation or analysis. Export information is saved as a .csv format for easy integration.

F or A dvanced and B asic T esting A pplications Starrett digital force gages can be used as handheld force gages for basic applications or as a force sensor when used with a FMM Digital Force Tester, MTL and MTH Manual Tester. Listed are the various test methods that can be performed: • Limit Testing - Use load, distance or a break condition and report results at the limit including maximum load and distance at maximum load. • Load Average Testing - The load average test measures the load from the start and end of a test sequence. • Time Average Testing - Set a time duration for a test. When load is measured at the start of the test, the test concludes at the end of the time duration. Average load is measured. • Cyclic Count Testing - Define the number of cycles, up to 99,999 to be completed. • Cyclic Duration Testing - Define the duration of cycles, up to 27 hours to be completed. • Constant Hold Testing - Hold at a distance or load for creep and relaxation results. The maximum duration is 27 hours. • Contact Closure/Switch Testing - Uses the DFC force gage to signal when an electronic switch is opened or closed as load is applied or removed.
DFC D igital F orce C ontroller The DFC is a revolutionary concept for force measurement using a handheld force gage.The DFCmay be used as a high-accuracy handheld force gage or as a digital controller for use with the FMM Digital Force Testers.

Compressive testing
Identifying tensile force characteristics such as peak load is critical in validating a product's safety and application. Whether it's consumer products, medical products, packaging materials or fasteners used in the building trades, tensile testing is a fundamental measurement available on all Lx systems.
Shear tests help measure the deformable mechanical properties of cosmetics, plastics, composites, fluids and other samples. Lap shear testing can be used to measure mechanical weld strength or the adhesive strength of epoxies.
Adhesive strength properties are measured to understand the bonding capabilities of coatings and glues on various types of materials- from paper to substrates to building materials. Both 90° and 180° testing can be performed to measure the peak holding strengths under standard test methods such as ASTM F88.
Compressive loads are important in evaluating packaging designs, such as top load testing. Core sampling of concrete-based products are measured to determine their strength. And springs are analyzed under load to determine spring rate based on free length.
Flexural testing
Coefficient of friction testing
Break, Fracture and Rupture testing Load rate testing
Flexural strength and material stiffness represent the combined effects of a sample's basic tensile, compressive and shear characteristics. Composites, wood products, paper products can be tested in both 3- and 4-point methods to determine their stiffness and resilience.
ASTM D1894 is a common test method for measuring coefficient of friction. Materials such as plastic sheeting can be tested to measure both the static and kinetic frictional characteristics. Other materials, such as flooring products are tested to determine their slip resistance and safety under various environmental conditions.
Destructive testing can involve tensile, compressive, shear and other test methods where the product is tested to failure. Often this testing is used to determine the "peak" measurements that occur prior to the break event. Lx system allow you to measure precisely based on stress, strain, load, displacement and time.
Load hold testing is a more complex testing method compared to testing to a set point at a specific velocity. Load hold testing can be used on consumer products, such as children's attire, to measure the pull strength of buttons and their resistance to breaking loads.
Contact closure testing
Insertion/Extraction testing
Creep and Relaxation testing
Spring testing
The "make and break" load for an electrical switch can be measured precisely. Load is applied to the switch and the peak load is measured when the switch closes/opens. This type of application can be tested on keypads, membranes and other materials that utilize a resistance change.
Insertion/extraction testing is performed on electronic components like jacks, medical devices, consumer products, and more. The loads are measured in both directions- tensile and compressive to determine the sample's characterization for the application and for product life- cycle determination.
Foam is a material where its deformation while under an applied load below its yield strength is measured and analyzed. Knowing the material's ability to maintain its specified deformation is important for comfort and longevity in its intended application.
Compression and extension springs are evaluated for spring rate and spring constant. Using free length or specified lengths at load targets, it's important to verify the performance of springs to ensure reliability for the intended application whether it's for aerospace or consumer products like mattresses.
