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 DFG 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.

1.0 INTRODUCTION
Thank you for choosing the DFG Force Gage.
The DFG is our basic digital force gage. It may be used as a handheld
instrument or mounted to our FMM Digital Force Testers or our manual
testers, models MTL and MTH. If more functionality is required, the DFG
is our advanced digital force gage.
This manual provides an overview and general instructions of how to
use the DFG Force Gage.

3.0 FORCE GAGE FUNDAMENTALS
3.1 KEYPAD AND NAVIGATION
The DFG keypad is multi-functional. There are four keys.
Each is described below.
1.70 (43.2)
3.1.1 ON/OFF/MENU KEY
This key is used to power the gage on/off. Press to power the gage on. Press and hold
for 3 seconds to power the gage off.
This key is also used to access the Setup Menu. When the gage is powered ON, press
to access the Setup Menu.
This key is also used to navigate UP when in the Setup Menu. p
3.1.2 ZERO KEY
This key is used to zero the displayed values. Press to zero load and if connected to the
FMM Digital Force Tester, zero distance.
This key is also used to navigate DOWN when in the Setup Menu. q
3.1.3 SOFTKEY 1
This is the left arrow key. It is used to move out of a setup when in the Setup Menu. t
This key may also be mapped to a specific function.
The Setup Menu has a Key setup function where you may assign how Softkey 1 performs.
For example, you can assign a SAVE function to the key. When pressed, the measured
values are "saved" to memory.
3.1.4 SOFTKEY 2
This is the right arrow key. It is used to move in to a setup when in the Setup Menu. u
Like the Softkey 1, it also may be mapped to a specific function. For example, you can
assign a MODE function to the key. Pressing the key can change the operating modes of the
gage. You can switch from Real Time to Peak Tension by pressing Softkey 2.Shown: Keypad mapping with display in NORMAL format

3.2.1 PRIMARY DISPLAY
The center of the display is used to display the primary result(s). This
result is displayed in a large format with a resolution of 5,000:1. When
tolerance is used, the displayed results will show in RED when the result
is "out-of-tolerance". Results "in-tolerance" are displayed in BLACK.
3.2.2 SECONDARY RESULT
The upper right display area shows secondary results. These results
vary depending on the force gage mode and the primary result being
displayed. For example, if the primary result is a peak measurement, the
secondary result displays the real time load being applied.

3.2.3 DIRECTION
Symbols are used to indicate the direction of load for the current readings.
3.2.4 TOLERANCE
When a tolerance is setup for your result, results that are "within" the
tolerance range are displayed in BLACK. If the results is "outside" the
tolerance range, the result is displayed in RED. The gage may also be
setup to give a sound if the result is "outside" the tolerance range. The
sound is configured in SETUP and may be a "beep", "Chirp" or "Tone".
3.2.5 BARGRAPH
The bargraph shows the measured load as detected by the load cell
sensor. The load is displayed from a center line.
Compressive loads fill to the left while tensile loads fill to the right.
Color is used to depict the load status relative to the full scale of the load cell.
The bargraph will display GREEN when the measured load is from 1 to
75% of the full scale capacity.
The bargraph will display YELLOW when the measured load is from
76% to 90%.
The bargraph will display RED when the measured load exceeds 90%.
If the measured load exceeds the full scale capacity of the load cell, the
primary display will show a RED "- - - -", indicating an OVERLOAD condition.
The bargraph also uses markers to show maximum values achieved during
a test. For example, a marker may depict a peak load measurement.
