2. Understanding Your Readings
- Weight: Your total body mass in kilograms (kg).
- Body Fat (%): The percentage of your total body weight that is fat.
- Body Water (%): The percentage of your total body weight that is water.
- Muscle Percentage (%): The percentage of your total body weight that is muscle.
- Bone Mass (kg): The total weight of your bones.
- BMI (Body Mass Index): A measure that uses your height and weight to work out if your weight is healthy.

- AMR (Active Metabolic Rate): The total number of calories your body burns in a day, including physical activity.
3. User Profiles and Automatic Recognition

- Once your profile is set up in the "beurer HealthManager Pro" app with your personal data, the scale will attempt to automatically recognize you based on your weight and body composition.
- If multiple users have similar measurements, the scale may prompt you to select your profile in the app or on the scale itself (if applicable).
- Ensure your activity level is correctly set in the app for accurate AMR calculation.
