Limitations; Evaluation Of Results; Body Weight / Body Mass Index - Beurer BF 520 Instruction Manual

– Stand still and upright during the measurement.
– Wait a few hours after unaccustomed physical activity.
– Wait approx. 15 minutes after getting up in the morning to allow the water in the body to distribute.
– Remember that only long-term trends are important. Short-term changes in weight within a few days are usu-
ally caused by a loss of fluid. Body water plays an important role towards our general well-being.
Important when measuring body fat/body water/muscle percentage/bone mass:
– The measurement may only be carried out while barefoot. Dry soles or callused skin can result in unsatisfac-
tory 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.

Body weight / Body mass index
