INDICATIONS FOR USE
The OHS Body Fat Analyzer measures weight and uses bio-electrical impedance analysis
(BIA) technology to estimate body fat, total body water percentage, bone mass, and muscle
mass in generally healthy children 10-17 years old and healthy adults.
It is intended for use in a domestic setting only.
Tips
To ensure the accuracy of measurement, please follow below instructions when
you start measurement.
Place the scale on a flat, hard surface. Soft surface such as carpet will affect the
performance of the scale.
Step onto the platform with bare feet. Stand still and keep full contact with the electrodes
until the measurement is complete.
Start measurement at least two hours after Getting up or Dining.
Avoid measurement immediately after strenuous exercise, sauna or bath, drinking, and
dining.
Always start measurement in the same time slot and on the same scale located on the
same flat, hard surface.
For maximum accuracy and repeatability, it is recommended that you should use the
device in the same time of the day and on the same location.
The condition of the skin on the bottom of your feet can affect the reading. The natural
effects of aging or activity can make this skin hard. Take the reading with clean, slightly
damp feet for best accuracy. If you are having a problem with operating this scale,
please contact customer service.
Body fat percentage estimates will vary with the amount of water in the body, and can
be affected by dehydration or over-hydration due to such factors as alcohol consumption,
menstruation, illness, intense exercise, etc.
