5.1. Taking a Measurement
- Place the scale on a hard, flat surface. Avoid carpets or uneven flooring.
- Step onto the scale with bare, dry feet. The scale features "Auto-on technology" and will activate automatically.
- Stand still until your weight is displayed and then flashes, indicating the measurement is complete.
- The scale will then calculate and display other metrics such as BMI, body fat, muscle mass, water weight, and bone mass.

The scale is equipped with "Auto-user detection" and can store data for up to 8 users. Once a user profile is set up in the app and initial measurements are taken, the scale will attempt to identify the user based on their weight range. If multiple users have similar weights, the app may prompt you to confirm your identity.
