battery after one minute.
8. I have tried all corrective actions, but still can’t solve the problem …
Please contact the Detecto Customer Service at 1-800-336-5282.
9. Why do I get a different body fat reading when I use a different brand of body fat scale?
Different body fat scales take estimations around different parts of the body and use different
mathematic algorithum to estimate the percentage of body fat. The best advice is not to make
comparisons from one device to another, but to use the same device each time to monitor any
change.

1. Why is it important to monitor percentage body fat (%BF)?
The absolute weight traditionally determines whether or not a person is obese. Weight
change in itself does not indicate whether it was the weight of body fat or muscle that
had changed. In weight management, it is desirable that muscle mass be maintained
while body fat is lost. Thus, monitoring the percentage of fat in the body is an important
step toward successful weight management and body health.
The optimal %BF of an individual varies according to age and gender.

2. How is percentage body fat (%BF) estimated?
The percentage of BF is measured by a method called Bioelectrical Impedance Analysis
(BIA). The use of BIA to estimate body fat has been pioneered since the seventies. It was
only in the past decade that the estimation of body fat using BIA technology was successfully
offered to the consumer as a compact bathroom scale. With BIA technology, a low intensity
electrical signal is sent through the body. The signal is very low and causes no bodily harm.
Depending on the amount of body fat of the individual, the electrical signal will flow with
a different degree of difficulty. The difficulty with which a signal flows through the body is
called electrical impedance. Hence, by measuring the electrical impedance and applying
to the data a proprietary algorithm, %BF can be estimated. Please note that the
percentage of body fat and body water will not add up to 100%.
Please be reminded that the %BF estimated with the scale represents only a good
approximation of your actual body fat. There exist clinical methods of estimating
body fat that can be ordered by your physician.
3. Why is it important to monitor percentage Total Body Water (%TBW) in the body?
Water is an essential component of the body and its level is one of the health indicators. Water
makes up approximately between 50-70% of the body's weight. It is present proportionally more
in lean tissue compared to fat tissue. Water is a medium for biochemical reactions that regulate
body functions. Waste products are carried in water from cells for excretion in urine and sweat.
Water provides form to cells; helps to maintain body temperature; provides moisture to skin and
mucosa; cushions vital organs; lubricates joints and is a component of many body fluids. The amount
of water in the body fluctuates with the hydration level of the body and state of health. Monitoring
the level of body water can be a useful tool for one's health maintenance. Similar to body fat
estimation, the %TBW function provided in this scale is based on BIA. The estimated %TBW may vary
according to your hydration level, that is, how much water you have drunk or how much you
have sweated immediately prior to the estimation. For better accuracy, avoid fluctuation in
hydration level prior to the estimation. The accuracy of the scale in estimating TBW will also
decrease with individuals suffering from diseases that tend to accumulate water in the body.

14
Please be reminded that the %TBW estimated with the scale represents only a good
approximation of your TBW. There are clinical methods of estimating total body water
that can be ordered by your physician.
4. When should I use the scale’s body fat and total body water functions?
For maximum accuracy and repeatability, it is recommended that the scale’s body fat
and total body water functions be used at approximately the same time of the day, e.g.
before breakfast in the morning. It is also a good practice to avoid swings in hydration
level of the body prior to the estimation. Establishing your own baseline value of %BF and
%TBW and tracking their changes is better than merely comparing your %BF and %TBW value
to the population’s “normal” value.
The estimates provided are not substitutes for physician assessments. Consult your physician
to determine what body fat percentage, total body water percentage, muscle mass
percentage, bone mass percentage and daily calorie intake are most ideal for you.
5. Why is the Athlete Mode necessary in a Body Fat Analyzer?
It has been found that body fat estimation using BIA could overestimate the percentage
body fat of adult elite athletes. The physiological variation of athletes in bone density
and level of hydration are two of the reasons said to account for the difference. The
Athlete mode is selectable only for people 15-85 years old.
6. Definition of an Athlete
The general consensus among researchers is that a quantitative dimension could be used
in defining an athlete. For example, an athlete could be defined as a person who consistently
trains a minimum of three times per week for two hours each time, in order to improve
specific skills required in the performance of their specific sport and/or activity.
7. What is Muscle Mass?
Our Body Fat Scale estimates the weight of Skeletal Muscle Mass in your body.
You have around 650 muscles in your body, and they make up roughly half of your body
weight. These muscles can be divided into three different groups:
skeletal, smooth and cardiac. All of these muscles can stretch and contract, but they
perform very different functions.
Skeletal muscle: Produces movement, maintains posture, stabilizes joints and generates heat
Smooth muscle: Found in the walls of hollow organs
Cardiac muscle: Exists only in your heart
8. Skeletal muscle (SM)
The tissue most commonly thought of as muscle is skeletal muscle. Skeletal muscles cover
your skeleton, giving your body its shape. They are attached to your skeleton by strong,
springy tendons or are directly connected to rough patches of bone. Skeletal muscles are
under voluntary control, which means you consciously control what they do.

15
Just about all body movement, from walking to nodding your head, is caused by skeletal
muscle contraction. Your skeletal muscles function almost continuously to maintain your
posture, making one tiny adjustment after another to keep your body upright. Skeletal
muscle is also important for holding your bones in the correct position and prevents your
joints from dislocating. Some skeletal muscles in your face are directly attached to your skin.
The slightest contraction of one of these muscles changes your facial expression.
9. What is Bone Mass?
Our Body Fat Scale estimates the weight of non-living bone mineral content. This is
important for monitoring and maintaining healthy bones through exercise and
calcium-rich diet.
An adult skeleton is made up of 206 bones, which come in several different shapes and
sizes and have specific structure. Your bones contain blood vessels, nerve cells and living
bone cells known as osteocytes. These are held together by a framework of hard, non-living
material containing calcium and phosphorous. A thin membrane called the periosteum
covers the surface of your bones.
Bone Mineral Content differs according to age and sex.
(Source: Rico et al. 1993)
The typical range of percentage bone mass (mineral content) of average men and
women is between 4.0 to 5.3% (Rico 1993).
10. What is the Calorie predictor daily calorie intake estimator?
The Calorie predictor function estimate the number of calories required based on your
body composition and user entered personal data. This tool can be used as a guide
when setting calorie goals during weight loss and exercise programs.
