Contraindications
The K-SENSORS are contraindicated under the following:
- On or near open wounds
- On or near burned tissue
- On or near the eye
- On or near fractures
- On patients having severe osteoporosis
- Not to be used for any purpose other than indicated
Indications
The K-SENSORS are indicated under the following:
- Take care of the strong attachment or hold of each sensor.
- For a better reliability of the isometric strength measurement, the attachment position
should always be the same and should be perpendicular to the exerted force direction.
- For a better reliability of the range of motion measurement, the initial position should
be set as the zero-amplitude angle and the start should be pressed at this time. Take
care to avoid compensation of other limbs.
Warnings and precautions
- Ensure your patient is able to keep his balance while watching the screen to avoid fall.
- Don't place any K-SENSORS components on unstable surfaces, or surfaces subject to
vibration.
- Use only a factory supplied wall pack power supply, charger. Use of another charger
may result in electrical shock or equipment damage.
- K-SENSORS are not intended for use while attached to wall pack power supply or a
charger. Never attempt to operate the instrument while it is connected to the charger
as electrical shock or damage to the instrument may occur.

- The K-SENSORS are not protected against ingress of liquids. Keep sensors dry. Do not
immerse the K-SENSORS or their accessories in water.
- The K-SENSORS are precision medical sensors. The K-SENSORS should be treated with
care. Do not drop, bang, hit or subject the sensors to strong shock . Be careful to have a
firm grip when holding them in order to avoid accidental fall of the system which may
cause damage to the K-SENSOR or injury to the patient/operator.
- Not recommended for use in extreme temperatures, high humidity, or direct sunlight
- Never disassemble or modify the system using any accessories not specifically
approved by KINVENT Biomécanique, LLC, this will void the warranty as well as reduce
immunity to electromagnetic interference, or increase electromagnetic emissions, and
result in improper operation.
- Medical Electrical Equipment needs special precautions regarding EMC. K-SENSORS
need to be installed and put into service according to the information provided in this
manual.
User qualification
- The K-SENSORS should only be used by trained professionals.
- The user must have received sufficient training in clinical procedures to get reliable
measurements.
Cleaning and disinfection
- The K-SENSORS and accessories are provided as non-sterile and are not compatible
with autoclave or other sterilisation techniques. Do not autoclave.
- Disinfect K-SENSORS prior to use. Low level or intermediate level disinfectants should
be used (e.g. alcohol wipes).
- Do not use bleach to clean the plastic parts, prefer alcohol blends.
Safe disposal
- Do not dispose of the K-SENSORS sensor in fire.
- K-SENSORS contain lithium-polymer batteries. Do not dispose of the batteries with
household waste
- K-SENSORS are not known to contain any hazardous materials. For proper disposal
instructions, consult your local waste management facility. E-waste recycling should
be used where available.

Calibration
K-SENSORS gives you metrics on the human muscular force. K-SENSORS are sold
already calibrated, to make them ready for use out of the box.
We recommend that the product be tested for calibration at least once a year under
normal use or sooner under severe conditions and usage. K-SENSORS are not user
serviceable and do not include a service manual. For more information on calibration as
well as special requirements, please contact your K-SENSORS dealer.
Interface
All K-SENSORS share the same interface
1- Multi colour LED
2- USB-C charge port
3- Power on/off command orange button
Get Started
You can charge your K-Sensor through the USB-A to USB-C cable provided or with
any USB-C charging cable. The sensor is supplied with the appropriate IEC 60601
compliant medical grade USB power supply. If a different charger is used, ensure that it
meets the minimum medical safety requirements and if unsure please do not use the
sensor while plugged in/charging
Press the orange power-on button on the K-Sensor. The indicator begins flashing
green. Your sensor is ON! Your sensor will turn off after 10 minutes of no Bluetooth
connection or no application connection.
Once the sensor is switched on, choose the corresponding sensor icon in the Home
Page. Select the body part you want to measure and then select one of the proposed
exercises. Once the K-Sensor is connected, the LED turns Blue.
While your sensor is connecting, do not load the sensor, do not step on the sensor, do
not move the sensor, and do not apply force on the sensor.
LED States
●The sensor can wake by plugging in the USB cable or pushing the orange button. The
GREEN LED starts blinking.
●When the sensor is connected via USB, the sensor begins to charge the internal
battery.
●After 10 min, if not connected to the application, it will automatically power off . The
battery will continue to charge indicated by a pulsing ORANGE light.
●Once the battery reaches full charge the sensor will indicate this by switching to
permanent WHITE light. If power is removed the sensor will power on again.
●When a successful connection over Bluetooth is attained then the light begins
flashing BLUE.
●If the battery is low, then a RED light will flash intermittently three times and every 5
seconds. Wireless range may be affected if operating under this condition.
●The sensor will switch off if the charge level is lower than 1%.
●A single push on the button will display the battery status via bright red, yellow, or
green light depending on the charge level.
