6. Operating Instructions
6.1 Taking a Measurement
For accurate results, take measurements at the same time of day under similar conditions. Avoid measuring immediately after intense exercise, bathing, or consuming large meals.
- Press the ON/OFF button.
- Select your user profile (P1-P4) by pressing the corresponding button, or press GUEST for a one-time measurement.
- Step onto the scale barefoot, ensuring your feet are centered on the foot electrodes.
- Hold the display unit with both hands, extending your arms straight out at a 90-degree angle to your body. Ensure your thumbs are on the top electrodes and fingers are wrapped around the bottom electrodes.
- Remain still until the measurement is complete and results are displayed. This typically takes a few seconds.
- The device will first display your weight, then cycle through other body composition metrics.

7. Understanding Your Measurements
The OMRON HBF-514C provides 7 key body composition indicators:

Body Fat Percentage: The proportion of fat to total body weight. High body fat can increase health risks.

Skeletal Muscle Mass: The weight of muscle attached to bones. Maintaining or increasing skeletal muscle mass is important for strength and metabolism.

BMI (Body Mass Index): A ratio of weight to height, used to classify underweight, normal weight, overweight, and obesity.

Resting Metabolism: The minimum number of calories required to maintain basic bodily functions at rest. Higher muscle mass generally leads to a higher resting metabolism.

Visceral Fat: Fat surrounding internal organs. High levels are associated with increased health risks.

Body Age: An estimate of your body's physiological age based on your body composition metrics compared to average data for your chronological age group.

Weight: Your total body weight.
8. Maintenance
