Index Smart Scale Measurement Method

The Index Smart Scale uses bioelectrical impedance to calculate your body composition. The device sends a small amount of electrical current (which you do not feel) from one foot through your body to the other foot. The device measures the electrical signal after it passes through your body to estimate aspects of your body composition.

The Index Smart Scale will upload the following body composition data:

• Body Mass Index (BMI):  Body mass index is your weight in kilograms divided by your height in meters squared. BMI is often used to estimate if a person is underweight or overweight
• Skeletal Muscle Mass: Skeletal muscle mass is the total amount of mass attributed to involuntary muscle. This excludes smooth and cardiovascular muscle. It is measured in pounds, kilograms or stones and pounds.
• Bone Mass: Bone mass is the total amount of mass attributed to dry bone weight. It is measured in pounds, kilograms, or stones and pounds.
• Body Fat Percentage:  Body Fat percentage is the percentage of total mass attributed to fat, including essential fat and storage body fat. Essential body fat is required for basic health.
• Water Percentage: Water percentage is the percentage of total mass attributed to fluid. This measurement can be used to indicate your level of hydration.

Note: For best accuracy, ensure you use the device under the same circumstances and at approximately the same time of day each time you use the device. Activities that temporarily impact your body's weight hydration and distribution of water can impact the accuracy of measurements. Garmin recommends waiting two hours before using the device after eating, drinking, exercising, bathing, or visiting a sauna.
