2.4 Tips for using the scale
Important when measuring body fat/body water/muscle percentage:
– The measurement may only be carried out while barefoot and it is helpful if the soles of your feet are slightly
damp. Completely dry soles can result in unsatisfactory results, as they have insufficient conductivity.
– Your feet, legs, calves and thighs must not touch each other, as otherwise the measurement cannot be per-
formed correctly.
– Stand still during the measurement.
– Wait several hours (6-8) after unusually strenuous activity.
– Wait approx. 15 minutes after getting out of bed so that the water in your body can be distributed.
The measurement is not reliable for:
– Children under approx. 10 years of age.
– Persons with fever, undergoing dialysis, with symptoms of edema or osteoporosis.
– Persons taking cardiovascular medication. Persons taking vascodialating or vascoconstricting medications.
– Persons with substantial anatomical deviations in the legs relative to their total height (leg length considerably
shorter or longer than usual).
Body fat guide
The following body fat levels provide you with a guideline (for further information, please consult your doctor!).
A lower level is often found in athletes. Depending on the type of sports, the intensity of training and the
person’s physical constitution, levels can be achieved that are even lower than the specified guidelines.

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 spe-
cified guidelines.
As the
percentage of muscle
differs from individual to individual, there are no generally valid guidelines.
