The scale rejects user profiles:
- with ages less than 6 years or more than 100 years.
- less than 80 cm tall or more than 220 cm tall.
The scale measures only the weight and body fat for the following users:
- under 18 years old
- over 70 years old
Note that for these users, body fat is only a reference indication. Outside the 18-70 years age range, it is preferable to take into account the change in body fat (the curve) to see if the user is increasing or losing body fat.
