FMD & MMD User Manual

1.0 Introduction Thank you and congratulations for selecting the Starrett FMD or MMD Series twin column testing frame. Your MMD and FMD Series testing frame may be used for tension and compression testing including specific test methods such as peak, break, constant hold, flexural, shear, peel, coefficient of friction and more. Your MMD and FMD testing frame should be used with Starrett equipment and accessories only. For optimum performance, your MMD and FMD testing frame should be maintained and serviced annually by an authorized Starrett representative. HAZARD MMD and FMD test frames are used in applications with inherent hazards from high forces, rapid motions and stored energy. Users should be aware at all times of moving components that are potentially hazardous, particularly moving crossheads. Failure to read and follow all operating instructions can result in serious injury to personnel and damage to equipment and facilities. Operation and service of MMD and FMD test frames should be by authorized personnel trained in their safe operation.

1.1 System Description Your Starrett MMD and FMD Series test frames are twin column testing frame that make up any of the following testing systems: • L3 Series System used for material testing • L2 Plus Series System used for advanced force measurement and analysis • L2 Series System use for force measurement L3 Series System An L3 Series System uses our L3 Series software operating on an all-in-one touchscreen workstation (L3 Workstation), combined with an MMD Series testing frame. L3 Series Systems are used to measure stress, strain, load, distance, height and time. L3 Series Systems are optimized for research & development, engineering and advanced quality control applications involving material characterization. L2 Plus Series System The L2 Plus Series System uses our L2 Plus Series software operating on an all-in-one touchscreen workstation (L2 Plus Workstation), combined with an FMD Series testing frame. The L2 Plus Series Systems are used to measure load, distance, height and time. They cannot be used with extensometers and cannot be used to measure and analyze stress or strain. L2 Plus Series Systems are used for advanced force measurement and analysis. L2 and S2 Series System L2 Series Systems are designed for high-volume testing in a production environment. The L2 Series System uses our L2 Series software operating on a table personal computer, combined with an FMD Series testing frame. L2 Series Systems are used to measure load, distance, height and time. The cannot be used with extensometers and cannot be used to measure stress or strain. L2 Series Systems are optimized for the production floor- they are easy-to-use, and provide basic force measurement results. The S2 Series System is an application-specific system used exclusively for testing compression and extension springs. MMD Series Test Frames MMD Series test frames are designed for more complex material testing and therefore, these testing frames have higher performance specifications compared to the FMD Series. MMD Series further distinguish themselves from an FMD Series by having two (2) extensometer inputs, plus optional analog inputs, analog outputs and digital I/O that may be used with ancillary equipment. FMD Series Test Frames FMD Series are for high load capacity force testing. FMD Series have lower performance specifications compared to the MMD Series. FMD Series cannot be used with extensometers. FMD Series cannot use analog input or analog outputs. FMD Series can be supplied with optional digital I/O.
