Product Overview
Thank you for choosing the TgForce3D Impact Running Sensor. The sensor and its associated iOS App
provide real time tibial shock feedback and additional features. This document provides instructions on
installing and operating the sensor. It also provides mandatory regulatory information. Please check
tgforce web site at http://tgforce.com for the latest information.
We recommend following the guidelines in this instruction manual before using the TgForce3D Sensor.
Getting Started
What's included
Tgforce3D Sensor
Velcro Band
USB Charging cable
+TgForce3D Mobile App on the Appstore
Apple iOS Requirements
●iPhone 5S+, iPad 2nd Generation+, iPod Touch 6th Generation
●iOS Operating System 11.0 or later
Downloading the TgForce3D App
You will need to download the free TgForce3D App to use your sensor.
1. Click on the App Store on your iOS device.
2. In the search toolbox, enter TgForce3D.
3. Locate the App and Install it (no charge). Do not download th TgForce App (Blue), it is for an
earlier version of the TgForce hardware.
4. Once the download is complete you can find TgForce3D App on your device.

Charging and activating the sensor
Charging
Before first use, it is recommended to fully charge the TgForce3D sensor. Plug the provided USB
charging cable into any USB port. Charging your sensor will take approximately 1-2 hours. When
charging is complete, the orange LED indicator light will turn off.
Activating the sensor
Slightly shaking the sensor will activate it. If the sensor was in sleep mode, LED indicator light will flash
red 5 times (or red and blue if an iOS device with TgForce App is active nearby). Note that the sensor
does not have an On/Off Switch. If the sensor has been unused for more than 5 minutes, it will enter
sleep mode to preserve battery charge. It will also enter sleep mode if the sensor is not paired within 5
minutes.
Pairing the TgForce3D Sensor
Make sure Bluetooth in enabled in the iOS device settings. The TgForce App will automatically look for a
nearby TgForce sensor and establish pairing. You can confirm pairing has been successful by looking at
the Bluetooth icon in the upper left corner of the TgForce App. When successful pairing is established,
the sensor LED indicator will flash blue 5 times.
Alternatively, you can pair the sensor manually by selecting the Settings Tab and ‘Find/Connect New
Sensor'.
Pairing has been successfully established.
There is no pairing with the TgForce3D sensor. Try shaking the sensor until pairing
occur. The sensor may be discharged or you may need to restart pairing using the
Settings/ ‘Find/Connect New Sensor' option.

Version 2.2 TgForce3D Sensor User Guide P a g e | 7Page 7
Attaching the TgForce3D Sensor
For accurate measurement, the sensor
must be attached to the anteromedial
aspect of the distal tibia
(in front and toward the middle of the
lower extremity). Use the provided
Velcro band. The Sensor must be
attached in way that is tight enough so it
does not slide on the skin.
It is very important to have the sensor
visual LED indicator on top; the charging
hole must be downward.
Note: The sensor can also be attached
using Adhesive tape such as the 3M
Nexcare Water Resistant Adhesive Tape.
If the sensor cannot be attached firmly
with the Velcro band, use this method.

Start Running
Push the Start button on the app. Once
you start running, you should see Impact
data being received and displayed.
Each time an impact is detected by the
sensor, the light will flash (blue if paired,
red if not paired)
If Audio feedback is activated (in the
Settings menu), you will be notified in
your earphone if the impact level is
above the gMax threshold.
You can adjust the gMax threshold in the
Settings menu.

Getting to know the TgForce3D App
The main Session view
Peak (PPA)
The Peak PPA (Peak Positive Acceleration) of the Tibia while
running is displayed in real time in g unit (1 g = 9.81 m/s2). It
is the maximum acceleration that occurs during the impact
phase of running. Since the sensor contains a triaxial
accelerometer, you can select any of the axis (X, Y ,Z) or the
magnitude of the three-dimensional vector (3D). By default
the App display the 3D Vector magnitude.
Average
This is the average PPA for the session (for the selected axis).
Calculated over the displayed number of steps.
Cadence
Number of steps per minute - counting both feet.
gMax Red threshold line
The gMax threshold can be adjusted in the Settings menu.
The top PPA value will switch from blue to red every time
the impact value is higher than the gMax threshold value. If
Audio Feedback is enabled, an audible sound (selectable in
the settings menu) will also be generated.
Start/Stop
After a session has been started with the Start Button, only
the Session screen is available. The Settings, History and
Users screens are available after stopping a session.
Stopping the session will provide 3 options: Saving the data
in history, Discard the session data and Resume the session.

Version 2.2 TgForce3D Sensor User Guide P a g e | 10 Page 10
The History view
Each session can be recorded for later review
and analysis. Selecting the History Tab provides
a table with all the sessions recorded. You can
review the latest 1000 steps of each session on
a chart or export the data to an iCloud folder
for analysis in a 3rd party software (csv
format).
For each session, the following information is
displayed:
●Start Date-Time of the session
●Average PPA (Peak Positive
Acceleration) during the session for
each axes and 3D vector.
●Average Cadence of the session
●Total number of steps during the
session.
●Left or right leg (as defined in the user
view)
●Shoe description for the session
Exporting data: , select the arrow - You can
use this feature to export the raw data from
the session. You need to have the iCloud
feature of your iOS device adequately
configured for using this function. The format
is CSV (comma separated value). You can
retrieve the data in the TgForce Folder of
iCloud.
Review Chart: Select the session, a detailed
chart will be displayed.
