Body Fat Analyzer
The body composition consisting of the human body is divided into four : body water, protein, minerals,
and fat. This Body Fat Analyzer measures resistances when electric current flows through the human
body to estimate body composition (Bioelectrical Impedance Analysis (BIA)). Containing water that
conducts electricity well, muscles have low resistances; on the other hand, fat contains no water, having
high resistances. Based on these differences, body composition is measured, and the measured
information is provided by the app.
This product can be used with mobile devices.( iPhone 5S iOS 9.0 or later / Adroid OS 4.3.3 or later)
Safety Precautions When Measuring Body Composition
1. Body composition measurement may be affected by food/water intake, sweating or urination,
menstrual cycles, changes in water content throughout the day, outside temperature, body temperature,
and etc.
2. As water metabolism in body works by hour, make sure to measure at the same time of day at room
temperature (20~25
℃
).
3. In order to avoid errors caused by water content in body, please measure after at least two hours
since waking up.
4. In order to avoid errors caused by food, please measure while fasting before a meal or two hours after
a meal.
5. Please measure after discharging feces and urine.
6. Measure before doing exercise or action that may reduce body water.
7. If you measure after extreme exercise or at high body temperature, the measurement result may
change.
8. If you move or talk while measuring, the measurement result may change.
9. Please stand up for about five minutes before measuring body composition and sit without putting
armpit and thigh on the body for the measurement.
10. It is recommended that women not take measurements when the body’s water content increases
during their menstrual cycle as the measurement result can be inaccurate in the period.
11. Please remove electronic devices or metal accessories from your body before measuring.
12. If you have metal implants in your body, please do not measure.
