Tanita TBF-531 Body Fat Monitor/Scale  
Principles of body fat percentage measurement  
The Tanita Body Fat Monitor/Scale TBF-531 allows you to estimate 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. Until now, your absolute  
weight has determined whether or not you were considered overweight or obese. In  
recent years, the definition of obesity has been refined to mean the presence of excess  
body fat. 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  
The TBF-531 uses the BIA (Bioelectrical Impedance Analysis) technique. In this method,  
a safe low-level electrical signal is passed through the body. It is difficult for the signal to  
flow through fat in the human body, but easy to flow through moisture in the muscle  
and other body tissues. The difficulty with which a signal flows through a substance is  
called impedance. So the amount of fat in the body can be accurately estimated by meas-  
uring the impedance. The signal used is very low, making it safe and imperceptible.  
The illustration on the left show how the signal travels through the body.  
Tanitas patented foot-paddesign sends a safe,  
low-level electrical signal through the body to deter-  
mine 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 nights  
sleep. For the most accurate reading, a person should take a body fat percentage reading  
at a consistent time of day under consistent conditions.  
Body Fat %  
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 ones lifestyle, job and activities.

Advantages of the Tanita TBF-531  
Previously, body fat percentage was determined by measuring the thickness of subcuta-  
neous fat by pinching it with calipers, or by laying a person on a scanning bed and pass-  
ing a current from hand to foot. However, these methods had problems; measurement  
values varied, professional skills were required, and extensive time was required for  
measurement. Currently, the standard methods of fat percentage measurement are  
DEXA (dual energy x-ray absorptiometry) and Hydrodensitometry (underwater weigh-  
ing).

Daily fluctuations in body fat percentage based  
on the BIA method  
Based on data from both the DEXA and underwater weighing methods, Tanita established  
a formula for estimating the percentage of body fat. There is a high correlation between  
measurements taken with the TBF-531 and those obtained through DEXA and underwa-  
ter weighing.

Useful features of the TBF-531  
The TBF-531 allows you to measure both weight and body fat percentage simultaneously  
as easily and simply as stepping on a scale.

Preparations before use:  
Inserting the batteries  
1. Open the battery cover on the back of the measuring platform.  
Open as shown  
Direction of the batteries  
2. Insert the supplied AA-size 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 to remove the batteries before storage.  
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.  
Attaching the support feet (carpet use only)  
Insert the support feet into the holes at the four corners on the bottom of the  
measuring platform.  
NOTE: Do not use the monitor on any carpeting that is more than 0.8 inches in thickness.  
Do not use the support feet on hard, flat surfaces, as the unit may tip over.  
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. To clean, use a dampened cloth and mild detergent. Use  
alcohol to clean the electrodes.  
When you change the batteries, exchange all four batteries at the same time with  
new AA-size batteries.  
If you need assistance, please call our toll-free customer service number at 1-800-TANITA-8.

How to measure body fat percentage  
Overview of measuring  
To get the most accurate absolute values, measurements should be taken while wearing  
no clothing, preferably in the evening, and after urinating. If you do not undress, always  
remove your socks or stockings, and be sure the soles of your feet are clean before  
stepping on the measuring platform. Stand erect on the platform. If used after bathing,  
the body must be completely dry.  
NOTE: Accurate measurement will not be possible if the soles of your feet are not clean,  
or if your knees are bent or you are in a sitting position.  
It is best to take measurements at the same time each day, preferably in the evening.  
If doing so is not convenient, remember to wait about three hours after rising, eating,  
or hard exercise before taking measurements. While readings taken under other  
conditions may not have the same absolute values, they are accurate for determining  
the percentage of change as long as the readings are taken in a consistent manner. To  
monitor progress, compare weight and body fat percentage measurements taken  
under the same conditions over a period of time.  
Setting and storing data in memory  
The TBF-531 can be operated as a body fat monitor only if data has been pre-programmed  
into one of the four PERSONAL keys. The weight only function works independently.  
The unit has an automatic shut-down function. If you do not step on the platform after  
selecting a PERSONAL key, the unit will automatically shut off in about 30 seconds.
