5.2. Weight Difference Display
The device can display the difference between your current weight and your previous measurement, making it easy to track changes over time.
- After a measurement, the weight difference from the previous reading will be shown on the display.
6. Measurement Functions
The OMRON HBF-217-BW provides the following measurements:
- Weight: Your current body weight.
- BMI (Body Mass Index): A measure of body fat based on height and weight.
- Body Fat Percentage: The proportion of fat in your body.
- Body Fat Percentage Judgment: Categorizes your body fat level (Low, Standard, Slightly High, High).
- Skeletal Muscle Percentage: The percentage of muscle attached to your bones.
- Skeletal Muscle Percentage Judgment: Categorizes your skeletal muscle level.
- Basal Metabolism: The minimum amount of energy required to maintain basic bodily functions at rest.
- Visceral Fat Level (for ages 18+): The level of fat surrounding your internal organs.
- Visceral Fat Level Judgment (for ages 18+): Categorizes your visceral fat level (Standard, Slightly High, High).
- Body Age (for ages 18+): An estimate of your body's physiological age based on your body composition.
Note: Body fat percentage, skeletal muscle percentage, and basal metabolism can be measured for individuals aged 6 years and older. Visceral fat level and body age are available for individuals aged 18 years and older.
7. Maintenance and Care
- Cleaning: The glass top design is easy to clean. Wipe the surface with a soft, damp cloth. Do not use abrasive cleaners or immerse the device in water.
- Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
