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.

5.6.2.2 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.
The load cell stem extends through the top housing of the force gage.
When using an FMM Digital Force Tester, it may be necessary to turn the
gage upside down for compression load applications. The "Flip" feature
lets you orient the display so it always reads "right-side up".
NOTE
The Softkeys automatically map to the display target regardless of whether the force gage
is in Normal or Flip view mode.

5.6.2.4 RADIX SETUP
The force gage can use either a period or comma for radix.
Filtering can be used to compensate for noisy test measurements and
to help dampen or smooth a reading and results. The DFG features an
internal sampling rate of 10kHz, 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.
