ONDITIONS OF USE
The measurements should take place without clothes, if possible, and always barefoot.
Since the body is subject to natural fluctuations (e.g. dehydration through sports or sauna, intake of food and
fluids), constant conditions should be ensured when measuring, so as to receive comparable values.
Care should be taken that the measurements are always carried out at the same time of day. Directly after get-
ting up in the morning, the water has not yet spread through the body. This means that the resistance is still rela-
tively high, due to the bad conductivity in the body. With increasing movements throughout the day, the water
spreads through the body, increasing conductivity, which causes the resistance, and thus the fat level too, to be
shown as lower. To determine the actual changes of body composition, it is therefore important to measure al-
ways at same time. An easy way of doing this is by always measuring a quarter of an hour after getting up in the
morning, either before or after using the toilet.
Despite the minimum current, persons with pacemakers or other implants, which emit frequencies, must
not use the body analyser scales!
Other implants, e.g. a titanium plate in the knee, pose no danger. Metals, however, conduct electricity extremely
well, which has the effect that body fat values are “beautified”, meaning that the actual fat level is higher than
shown by the scales. Tendencies, on the other hand, can be determined just as well. In women, menstrual factors
have an effect on the measurement results, since hormonal fluctuations influence the body's water balance. If the
body contains all lot of water, the fat values are lower, if less water is contained, the values are a little higher.
When a woman is pregnant, there is no danger for the unborn child. But due to larger water deposits during
pregnancy, the values are distorted making the measurement senseless.
