Information on body composition
19. Information on Body Composition
Principle of body composition calculation
Body fat has low electric conductivity
HBF-255T measures the body fat percentage by the Bioelectrical Impedance (BI) method. Muscles, blood vessels and bones are
body tissues with a high water content that conducts electricity easily. Body fat is tissue that has little electric conductivity. The
unit sends an extremely weak electrical current of 50 kHz and less than 500 µA through your body to determine the amount of fat
tissue. This weak electrical current is not felt while operating the unit.
In order for the scale to determine your body composition, it uses the electrical impedance, along with your height, weight, age
and gender information to generate results based on OMRON’s data of body composition.
Recommended measurement times
Understanding the normal changes in your body fat percentage can help
you in preventing or reducing obesity. Being aware of the times when the
body fat percentages shift within your own daily schedule will assist you
in obtaining an accurate trending of your body fat. It is recommended
to use this unit in the same environment and daily circumstances. (See
