In addition the characteristic frequency for the subject is determined as well as total cell
membrance capacitance. These estimates are then used in algorithms to give body water
and fat-free mass.
6.2 SFBI Mode
This mode measures BI parameters over a frequency range of 4-1000 kHz. There are 8
selectable frequencies of which 5 are fixed and 3 are user definable. The 5 fixed
frequencies are: 5, 10, 50, 100, 500 kHz, and the 3 user definable frequencies may be
any in the range of available frequencies. A user may also specify the number of
measurements to be taken, with a specified measurement interval.
The SFBI function is included to allow a user to compute and present estimates of body
composition using published algorithms.
6.3 Predetermined Measurements Settings
Touching the arrow button next to the “Measurements” selection box allows the
selection of single or continuous measurements, or several measurements made spaced
at a selected interval of time. In continuous mode, another measurement is commenced
immediately after the previous measurement has been completed. In interval mode,
another sequential measurement is made after the interval of time selected (in seconds).
For Interval measurement setting, the interval between measurements can be selected
by touching the arrow buttons next to the “Interval” edit box or by using the keypad
(see Start up Screen section) that is selected by touching the “Interval” edit box.
For Interval and Continuous measurement settings, the number of measurements can
be selected by touching the arrow buttons next to the “Number” edit box or by using
the keypad (see Start up screen section) that is selected by touching the “Number” edit
box.
