GENERAL INFORMATION

PRODUCT WARRANTY

Starrett force measurement products carry a 3-year (from date of
purchase) warranty against defects in material and workmanship (parts
and labor), subject to factory inspection.

Starrett will repair or replace, at its option, any part or parts found to
be defective in workmanship or material. Starrett warrants repaired or
replaced parts for the balance of the original warranty period or 90 days,
whichever is longer. Parts returned to the factory under warranty will
be repaired at no charge. Freight charges to the factory will be paid by
the customer. Return freight charges to the customer will be paid by
Starrett.

This warranty does not cover damages from such causes as abuse,
accident, neglect, fire or freight damage. It does not apply to defects
resulting from modifications made by the customer or improper use of

the system or its components.

DISCLAIMER OF LIABILITIES

Starrett shall have no liability or responsibility to the customer or any
other person or entity with respect to any liability, loss or damage caused
or alleged to be caused directly or indirectly by this documentation,
or the hardware described in it. This includes but is not limited to
any interruption of service, loss of business or anticipatory profits, or
consequential damages resulting from the use or operation of hardware
or equipment.

GENERAL SAFETY PRECAUTIONS

Force measurement systems are potentially hazardous. Prior to
operating your testing system, Starrett recommends that you read and
understand the instruction manuals for your system and components
and that you receive training on the proper use of this equipment from
your authorized Starrett representative.

Observe all warnings and cautions identified in this manual for your
equipment. A warning identifies a function that may lead to injury
or death. A caution identifies a hazard that may lead to damage to
equipment or loss of data.

Starrett products, to the best of our knowledge, comply with various
national and international safety standards as they apply to material and
force measurement testing. This Starrett product has been tested and
found to comply with the following recognized standards:

• EN61010-1 Safety Requirements for Electrical Equipment

• EN61000-6-3 EMC Generic Emissions Standard

• EN61000-6-1 EMC Generic Immunity Standard

• Starrett also certifies that this product complies with all relevant EU
directives and carries the CE mark.

ELECTROMAGNETIC COMPATIBILITY

Your DFC Force Gage is designed to comply with International
Electromagnetic Compliance (IEC) standards.

To ensure reproduction of this EMC performance, connect this equipment
to a low impedance ground connection. Typical suitable connections are
a ground spike or the steel frame of a building.

WARNINGS
EMERGENCY STOP (FMM SYSTEM APPLICATIONS)

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 (FMM SYSTEM APPLICATIONS)

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 Grip 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

Disconnect equipment from the electrical power supply before removing
any electrical safety covers. Disconnect power when replacing fuses.
Never reconnect power while the covers are removed. Never operate the
system with protective covers removed.

ROTATING MACHINERY HAZARD (FMM SYSTEM APPLICATIONS)

Always disconnect power before removing covers that protect the user
from the internal rotating mechanisms. If maintenance to the drive
mechanism is required, and power is needed to perform maintenance
to the drive system, maintenance should be performed by an authorized
Starrett representative who has received factory training on performing
such procedures.

3.5 LOAD SENSOR MEASUREMENT

The load cell sensor, within the force gage housing, has a measurement
accuracy of better than 0.1% full scale and a safe overload rating of
200%. Force gages with a load capacity of 200 lbf (1000N) and below
are fitted with an M6 threaded load stem. The 500 lbf (2500N) force
gage model is fitted with an M10 threaded load stem.

NOTE

1. Load must always be applied axially. Use care and prevent any side
loading on the sensor. Side loading can affect the measurement
accuracy and lead to load cell damage.

2. Load cell sensors should NEVER exceed their rated full scale
capacity. Overloading the load cell sensor will lead
to irreparable damage.

3. Load cell should go through a 10 minute
"warm-up" period if the force gage has been
turned off for an extended period of time. Turn
the force gage on and wait 10 minutes for the
load cell electronics to warm-up.

4.4 SAVING RESULTS

The DFC feature an internal memory for saving results for the purpose
of calculating and displaying statistics. You may save up to 99 individual
results in memory.

Results saved to memory MUST be of the same type. You cannot have
mixed type results. For example, you cannot save tension results with
COF results. Results MUST be of the same type.

Results obtained using the TESTS feature are saved in pairs. For each test,
there is a Load and Distance result (L-D). You cannot save results from
different types of tests. For example, you cannot save results from a Load
Limit test with results from a Break Limit test. Each load-distance pair of
results must have come from the same test type: Load, Distance or Break.

For example, you may have a SHORTFALL = 15lbf. When 15lbf is measured,
the load averaging will start for the DURATION you have specified.

If the measured load falls BELOW the SHORTFALL, the test is invalid.
Averaging will stop. For the test to be valid, the measured load must
achieve the SHORTFALL to start the test and the applied load must

5.3.2 USER SCALAR

The User Scalar is a conversion value to use for a custom unit of measure.
For example, assume you want to determine the torque when applying a
force onto a 18-inch armature using the DFC Series force gage.

You create a user label called FLB (foot pounds or ft-lb). Since the
armature is 18-inches in length, 18 inches = 1.5 feet.

When using the USR units, load is always based on Newtons. Therefore,
convert Newtons to lbf using 0.2248. 1 Newton = 0.2248 lbf.

Determine the Scalar value using the following:

(0.2248) x (1.5) = 0.3372

0.3372 is the scalar value to use.

5.3.3 IN/MM

Use in when you want your User result to be in imperial units. And use mm
when you want your User result to be in SI units, based on metric values.

NOTE

UNITS may be assigned to Softkey 1 or Softkey 2. When assigned, pressing the Softkey will
allow the user to change units of measure each time the key is pressed.

5.5. TESTS (FMM FORCE TESTER)

The DFC Force Gage can be used as the universal interface for systems
comprised of a DFC Force Gage with an FMM Digital Test Frame. The
force gage is used to setup the test method to be used. The force gage
is also used to setup the FMM Digital Test Frame's test velocity and
any associated distance setpoints for a test. There is no need to setup
of the force gage and then setup the digital force tester. All test setup
parameters are done through the DFC Force Gage.

The DFC Force Gage will also display load and distance information for your test.

5.5.1. TEST MODE

When the TEST MODE = OFF, the DFC Force Gage operates as a classic
digital force gage. If operating with the FMM Digital Test Frame, you will
configure the force gage and the force tester independently.

Selecting a TEST MODE configures the DFC Force Gage as a "controller". As a
controller, the DFC Force Gage is used to setup three common test methods.
The gage serves as the universal interface to the FMM Digital Force Tester
while also serving as the load measuring and display instrument.

5.5.2. LOAD LIMIT TEST METHOD

When the TEST MODE = LOAD LIMIT, the DFC Force Gage is used to perform
a Load Limit test. All setup parameters for the test are performed through
the force gage. Test speed is configured through the DFC Force Gage.

The Load Limit test establishes a load setpoint that concludes the test.
When the test reaches this load setpoint, the test is complete. The FMM
Series crosshead will stop. The force gage will display the Distance at
the Load Limit.

5.5.2.1 LIMIT TYPE

The Limit TYPE is used to specify whether the test is a tensile (pull) or
compressive (push) test. If the TYPE=TENSION, the crosshead will move
in the tensile direction and move upward. It the TYPE=COMPRESSION, the
crosshead will move in the compression direction and move downward.

5.5.2.2 LIMIT TARGET

The Limit TARGET is the load value when you want the test to finish.
Enter a TARGET VALUE. When the test starts, the crosshead will continue
to move until the TARGET VALUE is achieved, as measured by the DFC
Force Gage. Once the load limit test has finished, the DFC Force Gage
will display the LOAD TARGET and the DISTANCE AT THE LOAD TARGET.

NOTE

At the completion of your Load Limit test, the DFC Series force gage will display the Load
Target value and the Distance at the Load Target value, i.e., the distance the crosshead

traveled to reach the Load Target.

crosshead will move in the compression direction and move downward.

5.5.3.2 LIMIT TARGET

The Limit TARGET is the distance value when you want the test to finish.
Enter a TARGET VALUE. When the test starts, the crosshead will continue
to move until the TARGET VALUE is achieved. Distance is read by the
encoder inside the FMM Series digital force tester. The distance is the
measured travel by the crosshead from the Zero position. The encoder
transmits the distance values continuously to the DFC Force Gage
and the gage displays the moving distance until the TARGET VALUE is
achieved. Once the TARGET VALUE is achieved, the test will finish.

5.5.4. BREAK LIMIT TEST METHOD

When the TEST MODE = BREAK LIMIT, the DFC Force Gage is used
to measure the maximum load and the associated distance at the
maximum load based on a break criterion that is used to conclude the
test. All setup parameters for the tester are performed through the force
gage. Test speed is configured through the DFC Force Gage.

The Break Limit test establishes the maximum or peak load that
occurred prior to the break condition that ended the test. When the
break condition occurs, the crosshead will stop. The DFC Force Gage
will display the maximum load and the distance at the maximum load.

5.5.4.2 MINIMUM BREAK

The MINIMUM BREAK is a pre-condition. The MINIMUM BREAK is a load
value. The MINIMUM BREAK is the load that must FIRST be achieved
BEFORE the DFC Force Gage begins to look for a drop in load. This drop
in load is the assumption that the material has fractured or ruptured.

The MINIMUM BREAK is used since some materials being tested exhibit
excessive load noise when load is first applied. This noise results in
substantial peaks and valleys of the load channel.

Min Break

5.00

Minimum Break Setup

5.5.4.3 % DROP

The % DROP is the percentage drop in load from a previous measured
maximum load. The DFC will continuous measured the load during
the test. Once the MINIMUM BREAK is achieved, the DFC Series will
continuously measure the load, looking for the maximum measured
load and then looking for when the measured load has dropped by a
percentage as defined by the % DROP value.

For example, if the MINIMUM BREAK is 25lbf, during the test, the DFC
will begin looking for a percentage decrease in the measured load AFTER
25lbf. If the maximum measured load is 100lbf, and the measured load has
decreased by a 10% DROP to 90lbf, the DFC Force Gage concludes the test.

5.8.2.2 ADJUSTING BACKLIGHT

The force gage features and adjustable backlight. This is useful to
counter issues with low or high ambient light conditions.

The force gage default is 20%. This means the backlight is displayed at
20% of its full intensity/brightness.

NOTE
Battery life is affected by the backlight setting. More power is consumed with a higher
backlight setting. At 20% backlight, and normal use, the force gage can provide over 30
hours of use.

5.8.3 USING FILTER

Filtering can be used to compensate for noisy test measurements and
to help dampen or smooth a reading and results. The DFC features an
internal sampling rate of 20kHz, ideal for capturing peak loads on brittle
materials. Since most tests do not require this sample frequency, you may
use filters for the displayed information or for measuring maximum loads.

NOTE

High sampling should only be used for short test durations on brittle materials. Sampling
at 100Hz is sufficient for most force measurement applications.
