TERRAILLON BODY FAT SCALE – INSTRUCTION MANUAL
3. How is percentage body fat (%BF) estimated?
%BF is measured by a method called Bioelectrical Impedance Analysis (BIA).
With the BIA technology, a low intensity electrical signal is sent through the body. The signal is very low and
causes no bodily harm. Depending on the amount of body fat of the individual, the electrical signal will flow
with a different degree of difficulty. The difficulty with which a signal flows through the body is called electrical
impedance. Hence, by measuring the electrical impedance and applying to the data a proprietary algorithm,
%BF can be estimated.
Please be reminded that the %BF estimated with the scale represents only a good approximation of
your actual body fat. There exist clinical methods of estimating body fat that can be ordered by your
physician.
4 . Why is it important to monitor percentage Total Body Water (%TBW) in the body?
and is a component of many body fluids. The amount of water in the body fluctuates with the hydration level of
the body and state of health. Monitoring the level of body water can be a useful tool for one's health maintenance.
Similar to body fat estimation, the %TBW function provided in this scale is based on BIA.
how much you have sweated immediately prior to the measurement. For better accuracy, avoid fluctuation in
hydration level prior to the measurement. The accuracy of the scale in estimating TBW will also decrease with
individuals suffering from diseases that tend to accumulate water in the body.
The optimal %TBW of an individual varies according to age and gender.
The table as follows may be used as a guide:

Women
Please be reminded that the % TBW estimated with the scale represents only a good approximation of
your TBW. There exist clinical methods of estimating body fat that can be ordered by your physician.
