According to the World Health Organization (WHO 2001), the
percentage of body water
should lie
within the following ranges:
Women: 50–55%
Men: 60–65%
Children: 65–75%
In persons with a high percentage of body fat, the percentage of body water very frequently lies below
the specified guidelines.
As the
percentage of muscle
differs from individual to individual, there are no generally valid guidelines.
3. Incorrect measurement
If the scale detects an error during weighing, “FFFF” or “Err” appears in the display.
If you step onto the scale before “
0.0
” appears in the display, the scale will not operate properly.
Possible causes of errors:
– The maximum load-bearing capacity of 150 kg
(330 lbs) was exceeded.
– The electrical resistance between the electrodes
and the soles of your feed is too high (e.g. with
heavily callused skin).
– Your body fat lies outside the measurable range
(less than 5% or greater than 55%).
Remedy:
– Only weigh the maximum permissible weight.
– Repeat weighing barefoot.
– Slightly moisten the soles of your feet if neces-
sary. Remove the calluses on the soles of your
feet if necessary.
– Repeat weighing barefoot.
– Slightly moisten the soles of your feet if necessary.
