3-6. Personal correction function
The DF870 estimates the body fat mass from measured impedance, based on the body fat mass measured
by the DXA method (dual-energy X-ray absorptiometry). The DF870 also estimates the visceral fat index,
based on the visceral fat area taken by a CT scanner. Because body fat mass and visceral fat are
especially important for health control, the DF870 has the “Personal correction function” to compensate for
the difference from the measured results of the base method. If your body fat percentage has been
measured by the DXA method, or if your visceral fat has been estimated by a CT scanner, set the user
parameter #030 Personal correction, and input the differences from the base method. Then you can
monitor your condition with more accurate results.
Furthermore, the Personal correction function also allows you to obtain results that are consistent with a body
composition monitor you have used in the past. Input the difference in the same way, and you can monitor
the conditions consistently.

Input values for personal correction
CT visceral fat area (cm
2
) = DF870’s visceral fat index
–
Visceral fat area taken by a CT scanner
(or other body composition monitor’s visceral fat)
DXA body fat mass (kg) = DF870’s body fat mass
–
Body fat mass measured by the DXA method
(or other body composition monitor’s body fat mass)
Set the personal correction in
the user parameter.
For how to set the user parameter, see the next and
subsequent pages.
Input the difference(s) from
the base method.
Input the differences using the above equations.
The input values are used to correct the measured
body fat mass/body fat percentage and visceral fat
area.
