Features

Easy-to-UnderstandDisplay

This unit calculates and displays the body fat percentage by using the Bioelectrical Impedance (BI) method. The displayed values for body fat and BMI* (Body Mass Index) 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-seedisplay.

Body fat percentage and body mass index are shown simultaneously in an easy-to-seelarge 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.

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.

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 fat mass / Body weight} x 100

Fat mass

Fat-freemass

Body Bones

Weight Blood

Muscles

Water

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.

	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

1.2 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.	Slightly moisten soles of your feet with a wet
		towel, then measure.
	When you step onto the electrodes, they feel	Allow the electrodes to warm by leaving the
		unit in a warm room for approximately ten

		minutes.
	Your body and feet are cold due to the blood	Warm your feet by immersing in hot water or
		staying in a warm room. Make sure the feet
	not circulating well.
		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.What You Should Know When Using This Unit

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-400sends 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-RayAbsorptiometry), 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 theBF-400works. 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-Raysand 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 5.
