Features

Easy-to-Understand Display

This unit calculates and displays the body fat percentage by using the Bioelectrical Impedance (BI) method. The displayed values for body fat and BMI are indicated in four ranges: “–”, “0”, “+”, “++”.

BI method: Bioelectrical Impedance method (full explanation on page 7) BMI: Body Mass Index.

This Index indicates the ratio between weight and height of a person. Common standard in the medical profession.

Formula (in metric): weight (kg) / height (m) / height (m).

Measurement is fast and simple.

After entering the data, a measurement can be started by simply pushing the power switch, selecting your personal ID number and stepping onto the measurement platform.

The calculated results are shown in an easy-to-see display.

Body fat percentage and body mass index are shown simultaneously in an easy-to-see large digital display and a bar display that can be read at a glance.

The memory function stores up to 4 personal profiles

The memory function can store individual settings (age, gender, and height) for up to four people.

(Body Mass Index)

The memory function also stores the previous measurement results for each ID

A simple press of the GUEST/MEMORY button displays the measurement results from the previous measurement.

Notes on Safety

Danger!

Never use this unit in combination with medical electronic devices such as: (1) Medical electronic implants such as pacemakers.

(2) Electronic life support systems such as an artificial heart/lung. (3) Portable electronic medical devices such as an electrocardiograph.

• This unit may cause the above mentioned medical electronic devices to malfunction.

Warning!

• Do not step on the edge of the unit as you may fall or lose your balance.

• Do not jump onto the unit, or hop up and down on the unit.

• Do not drop the unit.

• Do not use the unit on tiles or other surfaces that may be slippery, such as a wet floor.

• Do not use this unit when your body and/or feet are wet, such as after taking a bath.

• People with disabilities, or who are physically frail, should always be assisted by another person when using this unit.

• Never start weight reduction or exercise therapy without the instructions of a doctor or a specialist.

• If battery fluid should get in your eyes, immediately rinse with plenty of clean water. Consult a doctor immediately.

Read and follow the “Important information regarding Electro Magnetic Compatibility (EMC)” in the Technical Data Section.

Save these instructions for future reference.

1.What You Should Know When Using This Unit

1. What You Should Know When Using This Unit

1.1 What is Body Fat Percentage?

Body fat percentage refers to the amount of body fat mass in regards to the total body weight expressed as a percentage.

This OMRON BF400 will provide your specific body fat percentage and body weight. It is also an excellent tool to estimate your body fat percentage and measure body weight on a continuous schedule.

Body fat percentage (%)

Body Weight

= {Body fat mass / Body weight} x 100

Body fat reading is affected by the change of water content in the body.

A person’s hydration level and blood circulation may have an effect on their body fat reading. In the table below are some situations which could affect the reading.

Fat mass

Fat-free mass

Bones Blood Muscles Water

Cause of Fluctuations Examples of Fluctuation

Water and food intake 1 to 2 hours after breakfast, lunch or dinner

After taking a bath or shower, immediately

Changes in blood circulation

after exercising, in extreme environments (warm or cold), during illness or extreme fatigue

1.What You Should Know When Using This Unit

1.2 Advice for Measurement

If the soles of your feet are dry or the temperature of your feet or the electrodes are extremely cold, it will not be possible to obtain stable measurements, which may lead to display error indication or inaccurate results.

Please pay special attention in winter because the air is dry and/or the temperature is low.

Conditions Actions

Feet are dry.

When you step onto the electrodes, they feel cold.

Your body and feet are cold due to the blood not circulating well.

Slightly moisten soles of your feet with a wet towel, then measure.

Allow the electrodes to warm by leaving the unit in a warm room for approximately ten minutes.

Warm your feet by immersing in hot water or staying in a warm room. Make sure the feet

are dried properly.

Recommended times for 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 this unit in the same environment and daily circumstances. (See chart)

1.3 Principles of Body Fat Percentage Measurement

The OMRON BF400 estimates the body fat percentage by the Bioelectrical Impedance (BI) method.

What is the Bioelectrical Impedance method?

Muscles, blood vessels and bones are body tissues having a high water content that conduct electricity easily. Body fat is tissue that has little electric conductivity. The BF-400 sends an extremely weak electrical current of 50 kHz and less than 500 µA through your body to determine the amount of fat tissue.

This weak electrical current is not felt while operating the BF400. The Bioelectrical Impedance Method safely combines the electric resistance with the

distance of the electricity conducted. Correct posture and consistent measuring conditions need to be maintained for the best results.

How to estimate the body fat percentage.

DXA (Dual Energy X-Ray Absorptiometry), has been the established method for accurate evaluation of body composition. OMRON has used research information from several hundred people using the DXA method to develop the formula by which the BF-400 works. The body fat mass and body fat percentage is calculated by a formula that includes five factors: electric resistance, height, weight, age and gender.

What is the DXA method?

The DXA method uses two different frequency X-Rays and rates of absorption of the body and determines the value based on the difference between the two.

People who may get erratic results

There are certain conditions, such as with dialysis patients, when significant differences may occur between the estimated and actual body fat values.

These differences may be related to consistently changing ratios of body fluid and/or body composition.

Also refer to: “Avoid Taking Measurements Under the Following Conditions” and “Cases When the Calculated Results May Differ from Actual Body Fat Percentages” in section
