PRINCIPLES OF ESTIMATING BODY FAT PERCENTAGE

GB

FEATURES AND FUNCTIONS

Tanita Body Fat Monitor/Scales allow you to measure your body fat percentage at home as easily as you measure your weight.

What is Body Fat Percentage?

Body fat percentage is the percentage of fat in your body. Too much body fat has been linked to conditions such as high blood pressure, heart disease, diabetes, cancer, and other disabling conditions.

The BIA Method

Tanita Body Fat Monitor/Scales use the BIA (Bioelectrical Impedance Analysis) technique. In this

Tanita’s patented “foot-pad”	method, a safe, low-level electrical signal is passed through the body. It is difficult for the signal to
design send a safe, low-
	flow through fat in the human body, but easy to flow through moisture in the muscle and other body
level electrical signal
	tissues. The difficulty with which a signal flows through a substance is called impedance. So the
through the body to
	more resistance, or impedance, the signal encounters, the higher the body fat reading.
determine its composition.

Body Fat Percentage Fluctuations in a Day

Hydration levels in the body may affect body fat readings. Readings are usually highest in the early waking hours, since the body tends to be dehydrated after a long night’s sleep. For the most accurate reading, a person should take a body fat percentage reading at a consistent time of day under consistent conditions.

Besides this basic cycle of fluctuations in the daily body fat readings, variations may be caused by hydration changes in the body due to eating, drinking, menstruation, illness, exercising, and bathing. Daily body fat readings are unique to each person, and depend upon one’s lifestyle, job and activities.

The graph on the left shows an example of daily body fat percentage fluctuations.

PREPARATIONS BEFORE USE

Inserting the Batteries

Open the battery cover on the back of the measuring platform. Insert the supplied AA-batteries as indicated.

Note: Be sure that the polarity of the batteries is set properly. If the batteries are incorrectly positioned the fluid
may leak and damage floors. If you do not intend to use this unit for a long period of time, it is advisable	Open as shown.
to remove the batteries before storage.
	Direction of the batteries.

Positioning the Monitor

Place the measuring platform on a hard, flat surface where there is minimal vibration to ensure safe and accurate measurement.

Note: To avoid possible injury, do not step on the edge of the platform.

Handling Tips

This monitor is a precision instrument utilizing state-of-the-art technology. To keep the unit in the best condition, follow these instructions carefully:

•Do not attempt to disassemble the measuring platform.

•Store the unit horizontally, and place it so that the Personal keys will not be pressed accidentally.

•Avoid excessive impact or vibration to the unit.

•Place the unit in an area free from direct sunlight, heating equipment, high humidity, or extreme temperature change.

•Never submerge in water. Use alcohol to clean the electrodes and glass cleaner (applied to a cloth first) to keep them shiny; avoid soaps.
