top plate. The precision aluminum crosshead is engineered for
MMD /FMD Series System Drive System
minimal deflection under full loads at full velocity. Within each
column are precision ballscrews. The ballscrews are preloaded. The
ballscrews rotated synchronously driven by a precision motion control
system. Overall, the system components provide an industry-leading
system with extraordinary axial stiffness.
Drive System
The drive system for your MMD Series test frame resides within the
back housing protected by a lightweight fiberglass housing. The drive
system connects to the lower end of the ballscrews using a belt and
pulley system. Motor rotation rotates the ballscrews synchronously
which moves the crosshead up or down with excellent position control
resolution.
Load String
The load string consists of the load cell sensor, clevis adapter and test
fixture. The load cell is mounted to the crosshead using a set screw
that secures the load cell to the crosshead surface.
Starrett recommends using low-profile load cell sensors for material
testing because of their excellent axial stiffness.
Starrett recommends that your load cell sensor is attached to a base
adapter. The base adapter is standard with ULC Series load cells and
optional for MLC Series load cells. The base adapter helps ensure a
proper surface mounting.
The test fixture is mounted using the clevis adapter. The clevis
adapter has an M16 thread and comes in either a 15.9mm or 31.8mm
diameter. The clevis adapter threads into the load cell sensors. The
test fixture slides onto the clevis adapter and is secured using locking
rings and a grip pin.
Communications
Communications between the L3 Series workstation and your MMD
Series test frame is via USB 2.0.

3.0 Lifting and Handling
The MMD and FMD Series twin column testing frames are heavy. Any
lifting and positioning should be done by authorized personnel in
accordance to local safety standards, e.g. training required by Occupa-
tional Safety and Health Act (OSHA) in the United States, or comparable
safety standards when installed internationally.
Proper rigging equipment is required for lifting and positioning all MMD
and FMD Series test frames. Personnel responsible for test frame
lifting and position must follow the instructions within this manual.
Personnel should contact Starrett if they have any questions about how
to safely lift and position the MMD or FMD Series test frames.
Starrett recommends leaving the MMD and FMD Series test frame
in its packaging while moving the instrument to its final site location
within your facility.
CAUTION
Make sure hallways and door openings are large enough to
safely move your MMD and FMD Series to its final site loca-
tion.
Make sure that floors leading to the final site location are
rated to support the weight of the MMD and FMD Series
while in its Starrett Packaging.
3.1 General Precautions
Starrett recommends that only individuals experienced with the
operation of lifting equipment and rigging techniques should attempt to
lift or move your MMD and FMD Series testing frames.
Equipment operators must have the appropriate licenses and have
complied with your local safety standards (e.g. the appropriate training
required by OSHA in the U.S. or appropriate safety institutions around
the world).
WARNING
NEVER lift the frame by the top plate. This plate does not
support the weight of the frame. The plate could break and
cause personal injury and equipment damage.
WARNING
Do not use a lifting device or straps rated for less than twice
the weight of the load frame. All lifting devices and straps
must be rated for a capacity at least twice the weight of the
load frame.
WARNING
Do not tilt an unsupported load frame more than 15-degrees
when it is in the upright position.
Lift by Crosshead
Do NOT lift by top plate

3.2 Unpacking Your System
Starrett recommends that you wait to unpack your MMD or FMD Series
once it has been located in its final site location.
Your MMD and FMD Series should be moved using a forklift or crane to
its final site location.
Starrett uses environmentally safe portable crating systems to trans-
port the MMD or FMD Series. These systems are reusable, so take
care to store them flat when you are finished removing your test frame.
Disassemble your packaging create as follows:
1. Remove the metal clips holding the top plate of the crate system.
2. Remove the wooden top plate.
3. Remove the metal side clips.
4. Remove one of the metal base clips.
5. Remove the wooden side where you removed the metal base clip.
6. Repeat steps 3-5 as your work around each side of the crate
system.
7. Remove the shrink wrap vapor barrier around the test frame. DO
NOT USE A KNIFE. Take care not to cut the shrink wrap as you
may accidentally damage the surface finish.
8. Review the Packing List to ensure all components have been
shipped. Contact Starrett if you find any accessories or compo-
nents missing.
9. Remove all accessories and components from the base and save
to a side location. Do NOT disassemble or remove any compo-
nents or parts from the Accessory packages. Retain all packaging
materials until the system is satisfactorily installed and all parts,
components and accessories are
accounted for and located.
10. Prepare to move the MMD or FMD test frame to its final site
location.
Starrett Crate Tool
WARNING
When removing the wooden sides from the crate system, you
should work with the help of an assistant to keep the oppos-
ing sides from falling off the bottom skid.
Once the top and sides of the crate system have been removed, leave
the MMD or FMD test frame in the base on the skid. The skid is
required if you choose to life the frame under the base.
