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.

The MMD Series features include:

• Precision motion controls including powerful motors with excellent
acceleration and position resolution

• High Axial Stiffness with granite base and adjustable deflection
compensation and linear error correction

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.

4.5.3 Installing Base Clevis Assembly

4.5.4 Installing Load Cell Sensor

The base clevis assembly threads onto the MMD Series base plate.
The clevis should screw all the way into the base plate for a secure
fit. Once the clevis is threaded onto the base plate, then screw the
two locking rings onto the clevis. The locking rings are used to secure
your bottom test fixture and allow you to align your test fixture to your
preference.

All Starrett load cell sensors are “plug & play” and are TEDS compliant
to IEEE 1451.4. All load cells have a 9-inch (230mm) length cable with
a bayonet-style threaded connector.

Connect the load cell sensor to the mating connector located on the
MMD Series test frame (located beneath the crosshead on the right­hand side). The load cell sensors must be aligned on the crosshead so
that the load cell sensor’s cable has sufficient slack.

4.5.5 Installing Load Cell Clevis Assembly

CAUTION
ALWAYS install the clevis assembly with the appropriate load
capacity consistent with the load capacity of your load cell
sensor.

The load cell clevis assembly threads into your load cell sensor. Use
the top locking ring to tighten the clevis against the load cell. Use the
bottom locking ring to tighten down on the test fixture attached to the
clevis assembly.

CAUTION
When tightening the locking rings to an S-beam load cell
sensor, take care not to apply too much torque as this torque
can stress the internal strain gauge, and damage the sensor.

4.5.6 Installing Testing Fixture

Starrett has hundreds of different types of testing fixtures from which
to choose for your application. Our fixtures easily install onto the clevis
adapter that is fitted to the load cell sensor and onto the base of your
testing frame. Two clevis adapters are available. Test fixtures slide
onto the clevis and are aligned and secured using a grip pin and two
locking rings.

5.0 System Operation

5.2 MMD and FMD Series Controls

This section will describe some of the basic system operating methods
using your MMD Series test frame when used with either L2 or L3
Series software. For complete operating instructions, please refer to
either the L2 or L3 Series User Guide.

5.1 Operating Principles

MMD Series control is performed using L3 software and a computer
workstation. The computer is an all-in-one, touchscreen computer
that communicates to the MMD Series test frame using USB
communications.

Load measurements are performed by high accuracy Starrett load
cell sensors per ASTM E4, ISO 7500-1 and EN 10002-2. Load
measurements are conditioned by the MMD Series controller
and displayed in various views for analysis. An internal, high
resolution encoder is used to measure position and velocity. Two (2)
extensometer ports let you connect extensometers for applications
requiring more precise strain measurements per ASTM E83, ISO 9513
or EN 10002-4.

This section will describe the manual controls located on your MMD
Series test frame.

5.2.1 Emergency Stop Switch

The Emergency Stop Switch is located on the left-hand side of the
MMD Series base. This switch interrupts power to the electrical drive
system and brings the system to a stop as quickly as possible.

WARNING

Engaging the Emergency Stop Switch does not remove power
to the system. When the Emergency Stop Switch is engaged,
power to the drive system is interrupted. No crosshead
movement is possible.

When operated, the Emergency Stop Switch locks down into a closed
position. The crosshead movement is disabled.

To reset or disengage the Emergency Stop Switch, press down and turn
counter-clockwise. The switch will release upwards and return power
to the drive system.

5.2.5 Over-travel Limit Switches

Limit Switches are located on the side of the column and used to
restrict crosshead travel. Position your upper and lower travel limit
switches so that they are approximately 2-3 inches above/below where
your crosshead will stop during a normal test procedure. These travel
limits will stop the crosshead should the crosshead come into contact
with one of the limits.

MMD /FMD Series Crosshead Travel Limits

6.0 Using Your MMD Series Test Frame

Detailed instructions for using your MMD Series tester are included
in the User Guides for the L3 Series Material Test software, L2 Plus
Force Analysis software, or the L2 Series Force Measurement software.
Included in the following paragraphs are basic instructions for some of
the key operating functions of your system.

6.1 System Settings Options

The following are basis setup instructions for your MMD Series test
frames. Many of these settings may be performed using L2, L2 Plus or
L3 Series software.

6.1.1 Setting Crosshead Travel Limits

Crosshead travel limits are used to prevent over-travel conditions that
can lead to load cell sensor damage or damage to your test fixture.

Two magnetic travel limits are located on your MMD Series test frame.
One switch is used to prevent crosshead movement upward beyond
the location of this limit. The other limit is to prevent crosshead
movement downward beyond the location of this limit. The crosshead
limits slide up/down and feature a magnetic sensor that senses when
the crosshead is at a position equal to the switch position. When the
switch senses the crosshead position, the crosshead stops. The jog
switch will only allow operation away from the travel limit location, e.g.
if moving up when the switch was activated, only the jog down
direction is enabled.

The Travel Range is established between the two
Travel Limits. The crosshead will automatically
stop when it reaches a travel limit.

CAUTION

ALWAYS set the travel limits so that the total travel range fits
the grip string and the maximum travel expected for the test.

CAUTION

The bottom travel limit should take into consideration
operator safety. This limit should be set to prevent pinch
hazards.

WARNING

NEVER reach within, or place any of your body within the
travel range when the crosshead is moving.

Bottom Limit Switch

42

6.1.2 Setting Crosshead Maximum Velocity

Using Lx Series software, you may adjust the maximum crosshead
travel velocity. The minimum velocity is factory set at 0.001mm/min
(0.00004 in/min).

The crosshead will move at the minimum speed when the test frame
is not connected to your Lx Series workstation to prevent accidental
overload conditions.

Your MMD and FMD Series can operate at its specified full velocity at
full load.

You can reduce full velocity 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 Motion setting.

4. Adjust the Max Velocity setting to your desired highest velocity.

5. Select Done.

Set Crosshead Maximum Velocity as follows:

1. Select Lx Symbol for Main Settings Menu

2. Select MOTION setting

3. Enter value for the maximum allowed crosshead velocity you
prefer

4. Select DONE

NOTE
The factory default setting is the maximum allowed velocity
for your system.

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 overload­ing.

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.

44

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

6.1.4 Setting Load Cell Sensor Limit

The Lx Series software lets you add load cell limits to help minimize
potential overload conditions. You can specify the maximum load that
the load cell can measure. Once this limit is achieved, the crosshead
movement will stop preventing further increased loading onto the load
cell sensor.

NOTE
Limiting the load cell measurement cannot eliminate overload
conditions due to shock on the load cell sensor or load cell
overloading at very high speeds. Some overload may occur
and in most situations, preventing permanent damage to the
load cell sensor’s electrical bridge is achieved.

CAUTION
Load cell overload is caused by operator error due to the
manner in which the test machine is operated and how the
test setup is constructed. Always exercise extreme care
when creating a test or when operating your machine. Star­rett load cells damaged due to misuse are not covered by our
standard warranty.

You can help minimize load cell damage by setting a load cell limit 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. Adjust the Max Load Allowed setting to your desired %. 100% is
the default. This means the load cell is allowed to measure up to
100% of its rated load capacity. Changing to 80% means the load
cell sensor can measure up to 80% of its rated capacity. Once
80% of the capacity is measured, the Lx software will issue a
message and stop any further crosshead movement or applied
load to the sensor.

5. Select Done.

Set Load Sensor Limit as follows:

1. Select Lx Symbol for Main Settings Menu

2. Select LOADS setting

3. Enter value for the maximum % of full scale load allowed for the
attached load cell sensor.

4. Select DONE

NOTE
The load cell sensor limits is based on the load cell sensor
installed on the machine. 100% is the factory default mean­ing the load cell is allowed to measure to full scale. If 50% is
entered and the sensor has a 2000N capacity, the sensor will
measure up to 1000N. If 1000N is measured, a measured
load beyond 1000N causes the test to stop.
NOTE
The load cell sensor limits helps prevent overloading.
However, overloading at high rates of speed, even with load
sensor limit applied, may result in an overload of your sensor.

starrett.com 45

6.1.5 Using Deflection Compensation

Deflection compensation is especially useful when operating your MMD
Series in Height mode and in applications where the measured height
of the sample is critical.

Deflection compensation effectively compensates for the deflection
in the MMD Series and the components used in the load string: load
cell sensor, clevis adapters, and test fixture. For best results, you
should perform deflection compensation using the accessories for your
sample. In addition, you should know the applied load that is being
used with your sample. For example, if you are testing a spring, you
should know what the load at your desired distance is prior to using
deflection compensation. Use this load as your load setpoint.

CAUTION
Deflection compensation involves the compression of the
load string onto a solid surface. Extreme care should be used
so as not to overload the load cell sensor during your manual
control of the crosshead.

Instruction Guidelines:

1. Place the MMD Series into Height mode.

2. Affix the load cell sensor and test fixture (platens) that will be used
in your testing.

3. Set the datum using the automatic datum function in your Lx
Series software.

4. Once the datum is established, place a solid hard object that is
parallel to the top platen that is connected to the load cell.

5. Place the MMD Series is slow speed mode:
Using L3 or L2 Plus Series software, select the speed icon and set
to slow speed.
Using L2 Series software, select the arrows on the tablet and set
to slow speed.

6. Zero both the Load (L) and Distance (D) on the controller view (L3)
or the tablet (L2).

7. USE EXTREME CAUTION- using the down jog key, slowly lower
the crosshead observing the applied load. Move the crosshead
downward until you reach the desired load on which to
compensate for deflection. Stop immediately once your controller
or tablet indicate this setpoint load value.

8. Record the applied Load value (L) and the Distance value (D).

9. Go to Settings - Corrections. Enter the Load value (L) into the
DEFLECTION FORCE field. Enter the Distance value (D) into the
DEFLECTION DISTANCE field.

10. Select DONE.

46

Activate Deflection Compensation by
selecting YES.

6.2 Using Lx Series Software

Your MMD Series should be operated using either L3 Series software
or L2 Plus Series software and an all-in-one computer workstation, or
using L2 Series software with a tablet computer.

Your MMD Series test frame features a Stop/Pause/Stop push button.
This button features an LED indicator that indicates that crosshead
status- whether or not the crosshead is active, moving or stopped.

6.2.2 Pausing an L3 Test Setup

When an extensometer is used and recognized by your system, a sym­bol displays in the header tool bar showing an active extensometer and
the instrument’s rated gauge length. When an extensometer is used,
it allows the user to momentarily “pause” a test using the Start/Pause/
Stop push button or by utilizing the pause function within your L3
Series software. It is sometimes necessary to pause a test in order to
remove an extensometer from a sample that is about to rupture/break
in order to protect the extensometer from potential damage.

6.2.1 Starting an L3 Test Setup

Starrett recommends using the Start/Stop push button to start a test
when using Lx Series software. Optionally, you may use the Start Test/
Stop Test target on the Lx Series controller view (See Lx Series soft­ware manual for detailed instruction on How to Perform Lx Testing).

To Pause an active test, press the Start/Pause/Stop push button until
the LED displays a flashing RED indication. This indicates that the
crosshead has stopped moving, but the test remains active. Pressing
the Start push button restarts the run.

NOTE
When a run is paused, the run state is also displayed by
the controller view. Selecting the Start symbol immediately
starts the run.

WARNING
Never remove a sample while the sample is under load.
When the Pause function is used, the sample may still be
under load and should never be touched.

NOTE
The Pause function is not available in L2 or L2 Plus Series
software.

Press Start/Stop switch or
press START TEST target to

7.0 Using Your FMD Series Test Frame

7.1.1 Starting an L2 Plus Test Setup

The FMD Series test frame may be used with either L2 Plus Force
Analysis software or with L2 Force Measurement software. The FMD
Series has no extensometer interface, therefore, it cannot be used to
calculate stress or strain when an external extensometer is required for
measuring sample elongations. Unlike the MMD Series test frame, the
FMD Series test frame also does not support analog inputs or outputs.
The FMD Series does support digital inputs and outputs when used
with the optional Application Builder software.

NOTE

The FMD Series test frame may be used with L3 Material
Test software provided you are not using an external
extensometer or analog inputs or outputs.

7.1 Using L2 Plus Force Analysis Software

L2 Plus Series software is designed for force measurement and
analysis applications. L2 Plus Series software is very similar to our
L3 Material Test software except it cannot be used for stress-strain
testing.

L2 Plus Series software is ideal for detailed force analysis performed
in the Engineering or Quality laboratory. L2 Plus Series software has
a variety of graphical analysis tools that allow for measurements and
analysis to be performed from the graph trace of your test.

®

8.2 Maintenance Procedures

The following are routine maintenance procedures that may be
performed by the user or by a non-authorized Starrett representative.
Starrett recommends that other types of maintenance procedures be
performed by your Starrett service representative.

8.2.1 Travel Limits

Both crosshead travel limits should be tested daily (minimally) or
before each shift in a multi-shift plant operation. To test the upper
switch, locate the switch so that the switch is about 25mm (1 inch)
above the crosshead. Position the lower switch so that this switch is
located about 25mm (1 inch) below the crosshead.

Use the jog switch to manually move the crosshead upward. When it
makes contact with the upper travel limit switch, the crosshead should
stop and the up jog switch should be inactive. Press the jog switch
down and the crosshead should travel down, away from the upper
travel limit. Continue to press the down jog switch until the crosshead
makes contact with the lower travel limit switch. Again, the crosshead
should stop and the down jog switch should become inactive. Use the
up jog switch to move the crosshead off the lower travel limit.

Clean the surfaces of your MMD Series with a damp cloth. Never use
abrasive cleaning products or products that can leave oily residue.
Simply use a damp cloth to remove dust and dirt.

Use a cover to protect the test frame from dust when not in use.

HAZARD
If the crosshead does not stop when it makes contact with
a travel limit switch, DISCONTINUE using the test frame.
Contact your Starrett service representative for immediate
service.

8.2.2 Emergency Stop

9.0 Calibration and Verification

The emergency stop switch should be tested daily (minimally) or before
each shift in a multi-shift plant operation. To test, manually position
the crosshead up or down. While the crosshead is in motion, depress
the emergency stop switch. The crosshead should stop. Press and
rotate the emergency stop to release. Press the jog switch to position
the crosshead up or down. The crosshead should move normally.

8.2.3 Fuse Replacement

See the Fuse Specification chart on page 14.

HAZARD

Make sure to shut all power to your MMD or FMD Series
system to OFF. Dangerous voltage may cause personal
injury.

NOTE

The MMD and FMD Series used with 110/120V input power
use two (2) 6.3A slow-blow fuse.

NOTE
The MMD and FMD Series used with 220,230, or 240V input
power use two (2) 3.15A slow blow fuse.

Factory testing is performed on your MMD or FMD Series test frame
prior to shipment to you. Starrett calibrates and verifies MMD and FMD
Series performance specifications using calibration equipment trace­able to international standards, e.g. National Institute of Standards and
Technology (NIST). This testing and calibration is to verify your system
will operate to its published specifications.

A complete calibration of your MMD or FMD Series test frame should
be performed on-site at the time of installation per your preferred or
required international standard, e.g. ASTM E4, ISO 7500-1, EN 10002­2, etc. This calibration should be performed by Starrett or an autho­rized Starrett representative. Starrett recommends that your system
undergo a calibration and verification at least annually.

If you MMD or FMD Series test frame is physically moved, a calibration
and verification is necessary.

A Starrett calibration compares the actual load values measured by
your MMD or FMD Series system and its applied load cell sensor to
a known “standard or artifact” that is traceable to national standards
and ensures that the load measurement complies with your particular
standard, e.g. ASTM, ISO, etc.

A Starrett verification ensures that your measurements are reading
correctly or within the published specifications. Verification of the fol­lowing measurements are provided during a Starrett calibration:

WARNING
Always replace the fuse with the correct type and amp rating.

To change the fuse, perform the following:

1. Ensure that power to your MMD or FMD Series is removed
entirely.

2. Ensure that the Power On/Off switch on your MMD or FMD
Series is in the OFF position.

3. Ensure that the Emergency Stop Button is in the Stop (Down)
position.

4. Verify that power to the machine is OFF. View the Start/Stop
button and make sure no light is displayed. Use the jog key
and make sure there is no crosshead movement.

5. Locate the Power Entry Module on the back panel of your MMD
or FMD Series frame.

6. Using a small flat screwdriver, remove the cap from the Power
Entry Module that covers the Fuse Compartment.

7. Grasp and remove the Fuse Holder.

8. Install a new fuse into the Fuse Holder. WARNING- the replace-

ment fuse MUST be the factory-specified type and rating as the
original. An incorrect fuse may damage the electrical circuits

inside your machine.

9. Re-insert the Fuse Holder.

10. Place the protective cap onto the Power Entry Module.

11. Reconnect the power cable to the MMD or FMD Series.

12. Dis-engage the Emergency Stop Button.

13. Turn the main Power Switch to ON.
