Algorithm using Bioelectrical Impedance Analysis (BIA)
Holding the device electrode lightly with the thumb and forefinger of both hands and a microcurrent that is harmless to the human body will flow.
It obtains the body fat by checking the resistance value of the part through which the current can't pass, and the skeletal muscle and the basic metabolic amount are analyzed by the algorithm of ONESOFTDIGM.
Anyone can easily check body composition.
Fitrus Plus is not a medical device and should not be used for diagnostics or treatment.
Do not use this device if you are dependent on any biometric devices, such as a cardiac regulator, medical ECG, mechanical heart, or heart-lung machine.
Fitrus Plus is using a BIA(Bioelectrical Impedance Analysis).
Therefore, the measurement value may change may depend on the environment and season.
Fitrus Plus uses sensitive sensors for measurements.
It may cause malfunction due to the heating element such as the stove or the low-temperature environment.
Do not use Fitrus Plus to measure your body composition during pregnancy or menstruation.
There will be discrepancies.
The electric current (under 150 uA of 50 kHz) is too low for anyone to sense or be affected by it.
If you do experience any sensations or symptoms, immediately cease its operation.
Do not disassemble or modify the device.
Avert any physical trauma to the device.
Requirements for the Safety
Make sure to remove any nearby devices that can cause wireless interference.
These sources include but are not limited to microwave ovens, wireless audio operating in the 2.4 GHz or 5 GHz bandwidth, and certain power sources.
These sources can cause slower performance or disconnection from Fitrus Plus and may also interfere with the Bioelectrical Impedance Analysis, resulting in inaccurate readings.
Do not eat or dismantle the battery.
Keep out of children’s reach.
You must follow local regulations when disposing of the device or any of its components and accessories.
Need to do the exercise that fits my body.
Set the goals for exercise and monitor changes in your body based on body fat and muscles.
Exercise with a right understanding of the body will change your lifestyle dramatically.
You will get the most systematic and efficient health care and body composition analysis.
Led Indicator Displays remaining battery and measurement notification.
B
Four Electrode Sensor A Bioelectrical Impedance Analysis (BIA) will be conducted via the four electrode sensors to determine your skeletal muscle mass, body fat percentage, and other components of your body composition.
C
Acceleration Sensor Your activity levels can be gauged via the acceleration sensors built into the device.
