The Fat Loss Monitor is an excellent tool to quickly measure your body fat percentage and body mass. Input your personal data. The monitor displays your estimated value of body fat percentage using the Bioelectrical Impedance Method, and indicates your body mass index in four ranges, low, normal, high and very high. This is important information you need to know to monitor your weight loss or maintenance program.

Your HBF-306C comes with the following components:

  • Unit
  • Instruction Manual
  • 2 “AAA” Batteries

Read all the information in the instruction book before using the unit.

WARNING! This monitor cannot be used with a pacemaker or other implanted devices. Consult the manufacturer of the implant device and your physician before using this monitor.

IMPORTANT SAFETY NOTES

To ensure the correct use of the product basic safety measures should always be followed including the precautions listed below:

  • Read all information in the instruction book and any other literature included in the box before using the unit.
  • Consult your physician or healthcare provider before beginning a weight reduction or exercise program.
  • Consult your physician before using this monitor when pregnant.
  • Operate the unit only as intended. Do not use it for any other purpose.
  • Properly dispose of used batteries. Do not throw the battery into the fire. The battery may explode.
  • Do not disassemble or modify the unit. Changes or modifications not approved by Omron Healthcare will void the user warranty.

USEFUL INFORMATION

The Fat Loss Monitor displays the estimated value of body fat percentage by the Bioelectrical Impedance (BI) method and indicates the Body Mass Index (BMI) range with the BMI classification bar.

Bioelectrical Impedance Method

  • Muscles, blood vessels, and bones are body tissues having a high water content that conduct electricity easily. Body fat tissue has lower electric conductivity.
  • The Fat Loss Monitor sends an extremely low-level electrical current of 50 kHz and 500 µA through your body to determine the amount of fat tissue. This weak electrical current is safe and not felt while operating
    the Fat Loss Monitor.

Body Fat Percentage

Body fat percentage refers to the amount of body fat mass as part of the total body weight described as a percentage.

  • Body fat percentage (%) = (Body Fat Mass in Pounds / Body Weight in Pounds) x 100

Estimated Body Fat Percentage

  • Hydrodensitometry, or underwater weighing, has been the established method for accurate evaluation of body composition. Omron has used research information from several hundred people using the underwater method to develop the formula by which the Fat Loss Monitor works.The body fat mass and body fat percent is calculated by a formula that includes five factors: electric resistance, height, weight, age, and gender.

Body Mass Index (BMI)

  • BMI is an internationally used index to show body composition by determining the balance between height and weight.
  • Body Mass Index (BMI) Formula
    • US – Calculated using pounds and inches with this equation:(weight in pounds x 703) / height in inches/height in inches
    • Metric – Calculated using kilograms and meters: weight in kilograms/height in meters/height in meters

The above-mentioned indices refer to the values for obesity judgment proposed by the WHO, the World Health Organization.

NOTE: The body fat percentage measured by this unit may significantly differ from the actual body fat percentage in the following situations:

  • Children in the growth stage
  • Elderly people
  • People with a fever
  • Body builders or professional athletes
  • Patients with osteoporosis who have very low bone density
  • Women who are pregnant
  • Post-menopausal women
  • People who have swelling
  • Patients undergoing dialysis

RECOMMENDED MEASUREMENT TIMES

Recommended times for taking a measurement

Understanding the normal changes in your body fat percentage can help you in preventing or reducing obesity. Being aware of the times when the body fat percentages shift within your own daily schedule will assist you in obtaining an accurate trending of your body fat. It is recommended to use the Fat Loss Monitor in the same environment and daily circumstances for each measurement. (See chart)

Omron-HBF-306C-Handheld-Fat-Loss -Monitor-FIG- \(2\)

When To Avoid Taking A Measurement

If a measurement is made under the following physical conditions, the measured body fat percentage may differ significantly from the actual one because the water content in the body is changing:

  • After drinking a large amount of water or after a meal (1 to 2 hours)
  • After drinking alcohol
  • Immediately after vigorous exercise
  • Immediately after a bath or sauna

CALCULATE YOUR FIT INDEX

The Fat Loss Monitor can be set to either NORMAL or ATHLETE mode. Body composition varies based on your FIT Index.

Calculate your FIT index by using the following formula.

  • FIT Index = Frequency x Intensity x Time

Based on your FIT Index use the following mode when setting your personal data.

  • NORMAL FIT Index < 60
  • ATHLETE FIT Index ≥ 60
