USEFUL INFORMATION
The reason calculated results may differ from actual body fat percentage
There are certain conditions, such as with dialysis patients, when significant differences may occur
between the estimated and actual body fat values.
These differences may be related to changing ratios of body fluid and/or body composition.
NOTE: The body fat percentage measured by this unit may significantly differ from the actual body
fat percentage in the following situations:
• Children in growth stage
• Elderly people
• People with a fever 
• Body builders or highly trained athletes
• Patients undergoing dialysis
• Patients with osteoporosis who have very low bone density
• Women who are pregnant
• Post-menopausal women
• People having swelling
Recommended Measurement Times
Understanding the normal changes in your body fat percentage can help you in preventing or reducing
obesity. Being aware of the times when the body fat percentages shift within your own daily schedule
will assist you in obtaining an accurate trending of your body fat. It is recommended to use this unit in
the same environment and daily circumstances. (See chart)
