Warnings

Emergency Stop

Press the emergency stop button whenever you feel there is an unsafe

condition during a test. The emergency stop button removes power to

the motor drive system causing the crosshead to stop.

Flying Debris

Eye protection, protective clothing and splinter/safety shields should

be used whenever any possibility exists of a hazard from the failure of

a sample, assembly or structure under test. Due to the wide range of

materials that may be tested and that may result in a failure which may

cause bodily injury, the precautions and preventative methods taken

prior to testing is entirely the responsibility of the owner and the user

of the equipment.

Crush Hazard

Always use caution when installing or removing apparatus and your

sample material between the frame’s crosshead and the base. A

potential pinch/crush hazard exists. Keep clear of the testing ﬁxture,

and particularly the jaw faces at all times. Keep clear of the crosshead

during movement. If available, always make sure the Pinch Load

feature is enabled. This will stop inadvertent crosshead operation if in

manual mode. Always ensure that other personnel cannot operate the

system while you are working within the test ﬁxture area.

Electrical Hazard

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.
