Care and Storage

Clean the main unit with a soft dry cloth. If the main unit is heavily stained, wipe it with a cloth lightly dampened with water or detergent, then wipe it dry with a dry cloth. Avoid an excessive amount of water, this can cause internal damage. Do not wipe the unit with benzene, gasoline; paint thinner, alcohol, or other volatile detergents.

Features of the product

Accurate measurement
The body fat percentage is measured based on the electric resistance and the personal data such as height, weight, age and gender. The measured results are closely correlated with the "underwater weighing method" and the DEXA (Dual Energy X-ray Absorbtiometry) method, which are said to be the standard measurements methods for measuring the body fat percentage.

Measurement is fast and simple
After setting the data, body fat mass can be measured by simply holding the grip electrodes and pushing the Start button. The measured results are displayed approximately 7 seconds after the Start screen is displayed.

Large and clear displays
The easy to read large digital and graphic displays can be understood at a glance. The measured results based on body fat percentage and on BMI calculations are displayed alternately, as well as their interpretations.

Memory
The memory can store the personal data (height, weight, age and gender) of up to 9 people simultaneously.

Small, lightweight and portable

HOW TO OBTAIN A CORRECT MEASUREMENT

The body fat monitor is a monitoring device. It should be used at a fixed point in time and with a fixed period between two measurements. For instance: once a week on a Sunday morning. With this in mind, please find in the next paragraph a table with recommended times for measurement.
There are conditions that are not suitable for taking a body fat measurement. There are also some exceptions that are excluded for taking a body fat measurement. This chapter will end with some recommendation before taking a measurement.

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 trend of your body fat. It is recommended to use this unit in the same environment and same daily circumstances. (See chart)

The conditions or circumstances NOT suitable for a correct 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 changes.

Exceptions

In some cases, the measured body fat percentage may differ too much from the actual body fat percentage. These exceptions are the people for who measurements may vary due to consistently changing amounts of water and tissue density within their bodies.

Recommendations for taking a measurement

If the palms of your hands are dry or the temperature of your palms or the grip of the electrodes are extremely cool, stable measurement is impossible, 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.

HOW TO INTERPRET MEASURED RESULTS

BMI Value

Graphical interpretation of BMI value (LOW >> TOO HIGH)
BMI is an internationally used index to show the body condition by checking the balance between the height and the weight.
It is calculated by the following formula:
BMI = weight / height²

* The above mentioned indices refer to the values for obesity proposed by the WHO (World Health Organization)

Body fat percentage

Graphical interpretation of measured FAT%, based on Deurenberg's* table below
