microFET3 Wireless Overview
microFET3 is an accurate, portable Combination Force Evaluation and Range of Motion testing system. It is a
battery operated, hand held device weighing less than one pound and fits comfortably in the palm of your hand.
microFET3 provides you with objective, quantifiable data from the time-tested art of “hands-on” manual
muscle and range of motion testing. microFET3 aids in the differential diagnosis, prognosis, and treatment
protocols for the neuromuscular and musculoskeletal disorders.
Recessed into the main outer shell is a polycarbonate overlay with clear lenses for the LCD displays (Liquid
Crystal Display), and 3 membrane switches. A red switch is located to one side of the unit in proximity to
where the thumb or the index finger is positioned during use.
As information from the gauges is processed, it is displayed in two LCD windows. During manual muscle
testing, the Peak Force LCD shows the force being applied against the transducer pad during the test, and it
displays the highest force reached when the test is concluded. The Duration/Secs LCD shows the duration of
the test from the time testing threshold was crossed until the test is concluded.
For inclinometer use the unit is placed on the starting point and an angle is set. The patient moves through the
range of motion and the second angle is set. Then by clicking the cycle switch one more time the difference
between both angles will appear in the left hand LCD window.
The newly updated microFET3 Wireless with radio frequency technology provides convenience for both you
and your patients. The wireless microFET3, when used with HOGGAN microFET clinical software, alleviates
the inconvenience of being wired to the computer and provides easier interaction with patients. A wireless
instrument allows greater freedom in the exam room or testing area, and eliminates dictating the location of the
computer and length of instrument cable so you can move freely during testing.
The microFET3 can also be used as a standalone gauge for capturing individual force measurements for any
muscle test and inclinometry test.

Care and Cleaning
Your microFET3 is built to provide long lasting, reliable service. As with any precision instrument, it
should be used with care. It should not be dropped, banged against hard surfaces, or used as a scale.
The microFET3's exterior surface can be cleaned with damp soft cloth. Small amount of household spray
cleaner can be used. Any cleaner residue should be removed with soft cloth dampened with clean water. We
recommend that you periodically inspect your unit for wear, and proper functioning.
Calibration
The microFET3 comes with a calibration certificate, ensuring that the unit was properly calibrated at the
time of shipment. To ensure continued accuracy and reliability your microFET3 unit should be
recalibrated annually, by a properly authorized service technician.
microFET3 Transporting/Storage
Hoggan Scientific strongly recommends that you store and transport the microFET3 in the hard sided
protective carrying case provided.
Operating Features
IMAGE A
Power On
Pressing the RESET button activates the microFET3 unit. The unit will power-up in the testing mode that
was last used. Refer to Image A above.
Power Off
The unit will turn itself off automatically after 3 minutes of inactivity. This helps to maximize battery life.
Reset Button
Besides powering on the unit, the RESET button can be used to clear the displays and re-initialize the unit.
This may be necessary occasionally. Refer to Image A above for location of RESET Button.
It is not necessary to press reset after each test. The microFET3 automatically begins recording new data
when the force threshold is crossed.

LCD Windows
Muscle Testing
Peak Force
During muscle testing the Peak Force LCD (right LCD Window) numerically shows the actual force being
applied to the transducer pad. At test completion, the maximum force value (peak force) is displayed. Refer to
Image D below.
Duration/Sec.
The Duration/Sec. LCD window (left LCD Window) shows the elapsed time (in tenths of second) from the
time the force threshold was crossed until pressure was released. Monitoring test duration is an important
element in maintaining consistency between tests. Also displayed in the Duration/Sec. window is the threshold
setting (Low or High). Refer to Image B below.

LCD Windows
Inclinometer Testing
When the unit is in inclinometer mode for inclinometer testing, numerical readings or data are displayed in both
LCD windows during the sequencing of inclinometry testing. Refer to Image C below.

Muscle Testing/Threshold Button
Pressing the MT/ THRESH button will cause the unit to enter “Muscle Testing” mode. Each successive press
of the MT/ THRESH button will alternate the high/low threshold feature
High: display “H” in the time display and fractional units in the “force” display
Low: display “L” in the “time” display and fractional units in the “force” display.
High is the most commonly used threshold setting. In the high setting, three pounds of force must be exerted
before the microFET3 will begin recording test results. High threshold displays in 0.10 lb. increments during
testing. See Image D below to see Threshold setting set to L –Low.
Image D
Threshold
Threshold refers to the amount of force required before the microFET3 begins recording test data. The
threshold level can be set to either High or Low setting, and is displayed in the duration/force window.
High Threshold
The High Threshold is most commonly used. In the High setting, three pounds of force must be exerted
before the microFET3 will begin recording test data. The High threshold allows for easier placement of the unit,
and reduces false starts. High threshold displays force in 0.1 lb increments (.44N) during testing. The unit
begins recording test data at 3.0 lbs force (12.1N), and records data in 0.1 lb increments up to 150 lbs (.44N
increments to 1320N). Pressing Reset does not change the threshold setting
Low Threshold
The Low threshold setting is designed for more sensitive, lower force readings such as when testing finger
and hand muscle weakness. Greater care must be used when positioning the unit while in the Low setting, as the
threshold of 0.8 lbs (3.6 N) is easily crossed. The unit begins recording test data at 0.8 lbs (3.6N) and records
data in 0.1 lb increments up to 150 lbs (0.8 increments to 1320N) Pressing Reset does not change the threshold
setting.

Inclinometer Button
Pressing the INCL button will put the unit in “inclinometer” mode. Refer to Image C below showing unit in
inclinometer mode.
Image C
Using a “two button” approach the right display shows the “live” readings until the Inclinometer cycle switch,
which is a red button located on the side of the microFET3, is pressed. After the inclinometer cycle switch is
pressed the first reading is moved to the left display, and the right display contains the “live” reading. See
Image D below for location of the red inclinometer cycle switch.
Image D
Pressing the inclinometer cycle switch again “freezes” the data in the right display. Then, press the INCL
button. This will subtract the number in the left display from the number in the right display. The final
inclinometer reading result or angle is displayed in the left display.
To begin the cycle of a new inclinometer test, press the INCL button again. The unit will zero out both displays
to begin the cycle again.

Force Measurement Settings
To select unit of measure to display force in Pounds, Newtons, or KGF follow these steps:
1. Press and hold the MT/threshold button for five seconds. The display will show units of measure options.
“L” = Lbs., “g” = KGF, “n” = Newtons.
2. Press the MT/THRES button to toggle through options. Refer to Image F below where “L” (Lbs.) is selected

3. Press the Reset button to return to test mode.
Wireless Mode - Power On/Off
To turn on RF or wireless mode for microFET3 for use with software follow these steps:
1. Hold the MT/THRES button down for 5 seconds for the force measurement setting mode.
2. Continue to hold the MT/THRES button down for another 5 seconds to turn on the wireless power.
3. The Peak Force display will show RF (wireless) (left LCD window), and the Duration/Secs (right LCD
window) display will show On or Off.
4. Press the MT/THRES to toggle the RF (wireless) power on or off. Toggle On for RF wireless mode to use
unit with software. Refer to Image G below.
