MOST IMPORTANT - READ BEFORE USING THE FDX FORCE GAGE
OVERLOADS: FDX provides overload protection of its load cell. However, EXCESSIVE
OVERLOADS or IMPACT LOADING will cause permanent damage.
Prior to reaching an overload condition, the FDX sounds the tone for
five seconds, then displays “HELP”. Continuing to apply force to the
FDX will damage the load cell. For overload protection by capacity,
see SPECIFICATIONS TABLE 3.
When HELP is displayed, it indicates:
• FDX is overloaded. Increasing the load will damage the load cell.
CORRECT LOADING: FDX is intended for axial loads only. Application of force to the load shaft
at an angle or twisting the load shaft will cause erroneous readings. If
these forces are excessive, damage will occur.
ATTACHINGIMPLEMENTS: Attach implements “finger-tight” only. Use of tools to attach implements
to the load shaft will cause damage to the FDX.
AC ADAPTER/CHARGER: Use only the AC adapter/charger, supplied with FDX.
Using other adapter/charger units may damage the gage.
CABLE CONNECTION: Turn FDX off before connecting or disconnecting a cable.
NiMH BATTERIES: Use of NiMH replacement batteries is recommended.
Do not use charger or USB cable if alkaline or lithium batteries are used.
Never install the batteries backwards.
Do not use batteries with different brand names or mix old batteries
with new.
Never crush, short-circuit, or incinerate batteries.
Do not use damaged batteries.
Recommend recycling batteries using a local collection program.

FORCE TENTM PAIN TEST
The FPX PainTest™Algometer uses the FDX Force Gage as its force sensor,
so FPX Algometer operation is the same as the FDX Force Gage.
When using the 1 cm2round rubber tip, the FPX Algometer display provides direct
pressure readings matching the world-wide pain testing standard:
• lbf / cm2
• kgf / cm2
• N / cm2
It is assumed the FPX Algometer user is a medical or therapeutic professional,
familiar with the broad field of pain testing.

FORCE TENTM PAIN TEST
The updated Force Ten™FPX Algometer performs pain diagnostic testing with the
advantages of a digital force gage. Newly added features include backlit display,
audible signals and USB output with data logging software for collection of patient
test results.
Pressure algometry is a reliable measure of pain in muscle, joint, tendons, and
ligaments. The FPX proves the benefits of applied medication, physiotherapy or
manipulation.
As treatment progresses, the FPX quantifies improvements or setbacks. Pain
threshold measurements provide unique information not obtainable by any other
method. The objective measurements give reassurance to patients by confirming
improvement.
> Pain Threshold -- the minimum pressure that induces pain in tender and trigger
points of tissue. The FPX quantitatively assesses the tenderness of hypersensitive
areas. The FPX 25, used for pain threshold testing, is appropriate for determining the
minimum pressure that triggers pain at the point of interest.
> Pain Tolerance -- the point where a painful pressure stimulus can no longer be
tolerated. The FPX, assesses pain-pressure sensitivity for maximum tolerated
pressure. The FPX 50 is used for pain threshold and tolerance testing; with a wider
range for comparative tests between a normal sensitivity control point and the area of
interest.
Algometers are used as a reliable method of quantifying tissue tenderness.
Before taking a measurement, you may wish to demonstrate the process to the patient
by pressing the algometer into the palm of the hand.
Using the Algometer:
1. Localize any sensitive areas you wish to measure by gentle but firm palpation.
2. Holding the gage by the handle, place the rubber-tipped load shaft over the
predetermined trigger point or area of palpable tenderness you wish to measure.
•Make sure the gage shaft is perpendicular to the skin surface.
•Stabilize any nodular muscular regions between the middle and index finger
of your indifferent hand.
3. Apply steady, gentle pressure at a rate of 1kg/cm2/sec. until the patient first feels
pain and responds by saying “now.”
4. Remove Algometer and record the value.

The gage is now ready for use with the same operating mode, units selection, and
configuration settings currently in use when the gage was last turned off.
C.2Zero the Display
For maximum accuracy and repeatability, the load cell should be “conditioned” before
the gage is zeroed. Apply two conditioning cycles in the same push / pull direction as
the planned test. The applied conditioning force should be more than the expected
test result. Conditioning reduces internal load cell stresses and tightens grips or
fixtures.
Conditioning is recommended for first time setup and when the applied force
changes direction.

C.3Display Force
The FDX uses three intuitive ways to display force values:
• Non-Peak Mode FDX displays normal (i.e. - instantaneous) force applied.
• Tension Peak Mode FDX displays highest peak tension force applied since the
gage was last cleared by pressing ZERO.
• Compression Peak Mode FDX displays highest peak compression force applied since
the gage was last cleared by pressing ZERO.
Peak values are always available in all modes. The FDX measures instantaneous
real time forces and continuously updates peak forces in tension and compression.
C.3.1 Non-Peak Mode
Displayed force values vary with the instantaneous
force applied. Use FDX in this mode for monitoring the
applied force in real time as it varies.
At any time tension or compression peaks are needed, they may be viewed by
pressing the PEAK button.
• Enter Non-Peak Mode Press PEAK repeatedly to cycle through the display modes
until the PEAK icon is not displayed.
• Clear Measurement Press ZERO to tare the gage and clear peak values before

C.3.2 Peak Mode
Peak force values displayed by FDX are the highest peak(s)
of tension or compression since peak memory was cleared.
If peak memory is cleared, the next peak value displayed will
be that of the next test. If additional tests are run after the
first test, without clearing the peak memory, the peak value
displayed will always be the highest peak of the series.
• Enter Peak Mode Press PEAK repeatedly to cycle through the display modes
until the desired PEAK icon is displayed.
• Clear Measurement Press ZERO to tare the gage and clear peak values before
each test for best accuracy and repeatability. See note below.
• Run Compression Test When the COMP PEAK icon is visible, begin compression test
by applying push force. Peak force is displayed. When a higher
compression force is applied, the new peak is displayed.
• Run Tension Test When the TENS PEAK icon is visible, begin tension test by
applying pull force. Peak force is displayed. When a higher
tension force is applied, the new peak is displayed.
•Recall Peaks Press PEAK to cycle through display modes.
• Clear Peak Memory Press ZERO to tare the gage and clear peak values.
• Return to Non-Peak Press PEAK until the PEAK icon is not displayed.
NOTE: It is important to know that the displayed peak value is the highest peak
since peak memory was last cleared. If ZERO is not pressed, while in COMP PEAK or
TENS PEAK mode, the peak values from previous tests will be held in memory. New
peak values will be not be detected.
Prior to actual test use, practice with FDX “Non-peak”and “Peak”modes to gain
familiarity. FDX in non-peak or peak mode is continuously measuring the
instantaneous force applied and continuously capturing peaks.

C.3.3 Error Messages
The FDX continuously monitors the applied force and displays error messages when
the force is outside the normal operating range. The FDX displays the following
messages when operator error or maintenance issues are detected:
1) TARE TOO HIGH –verifies that the tare force is
within the recommended operating range.
StoP is displayed when:
Too much tare force is applied.
Tare is more than 20% of rated load cell capacity.
Recovery: reduce tare & press ZERO.
2) OUT OF RANGE –detects operator error or
accidental use of the gage above the specified
full scale. Monitors force on the load cell and
sounds tone when force is over capacity.
The tone sounds as a reminder that the accuracy
of values above full scale is not guaranteed.
A 5-second tone sounds when:
Too much force is applied.
More than 105% of full scale reading.
Recovery: Reduce the applied force.
3) !!! OVERLOAD !!! –detects operator error or
accidental overload. Senses total force on the
load cell (tare + load) and is not affected by tare.
Too much force is applied.
More than 120% of full scale load is applied.
Gage may be damaged.
Recovery: reduce force & check calibration.
