The scale cannot register profiles who are:
- Less than 6 years old or more than 100 years old
- Less than 80 cm (2.6 feet) or more than 220 cm (7.22 feet)
The scale only measures the weight and body fat for the following users:
- Less than 18 years old
- More than 70 years old
Note that for these users, body fat mass is only a reference value. Outside the range of 18-70 years, it is preferable to take into account the evolution of the body fat mass (the curve) to see if the user is taking or losing body fat mass.
