BODY WATER -WHY MEASURE IT? Body water is the single most important
component of body weight. It represents over half of your total weight and almost
two thirds of your lean body mass (predominantly muscle). Water performs a number
of important roles in the body:
All the cells in the body, whether in the skin, glands, muscles, brain or anywhere
else, can only function properly if they have enough water. Water also plays a vital
part in regulating the body's temperature balance, particularly through perspiration.
The combination of your weight and fat measurement could appear to be 'normal' but
your body hydration level could be insufficient for healthy living.

Body water measurement results are influenced by the proportion of body fat and
muscle. If the proportion of body fat is high, or the proportion of muscle is low
then the body water results will tend to be low. It is important to remember that
measurements such as body weight, body fat and body water are tools for you to use
as part of your healthy lifestyle. As short term fluctuations are normal, we suggest
you chart your progress over time, rather than focus on a single days reading.

WHAT DOES MY BMI VALUE MEAN?
Body Mass Index (BMI) is an index of weight-for-height that is commonly used to
classify underweight, overweight and obesity in adults. This scale calculates your
BMI value for you. The BMI categories shown in the chart and table below are
recognised by the WHO (World Health Organisation) and can be used to interpret
your BMI value.
Your BMI category can be identified using the table below.

IMPORTANT: If the chart/table shows that you are outside of a 'normal' healthy
weight range, consult your doctor before taking any action. BMI classifications are for
adults (age 20+ years) only.

QUESTIONS & ANSWERS
How exactly is my body fat and water being measured?
This Salter Scale uses a measurement method known as Bioelectrical Impedance
Analysis (BIA). A minute current is sent through your body, via your feet and legs.
This current flows easily through the lean muscular tissue, which has a high fluid
content, but not easily through fat. Therefore, by measuring your body's impedance
(i.e. its resistance to the current), the quantity of muscle can be determined. From
this, the quantity of fat and water can then be estimated.
What is the value of the current passing through me when the measurement is
taken? Is it safe?
The current is less than 1mA, which is tiny and perfectly safe. You will not be able
to feel it. Please note however, that this device should not be used by anyone with
an internal electronic medical device, such as a pacemaker, as a precaution against
disruption to that device.
If I measure my body fat and water at different times during the day, it can
vary quite considerably. Which value is correct?
Your body fat percentage reading varies with body water content, and the latter
changes throughout the course of the day. There is no right or wrong time of the day
to take a reading, but aim to take measurements at a regular time when you consider
your body to be normally hydrated. Avoid taking readings after having a bath or
sauna, following intensive exercise, or within 1-2 hours of drinking in quantity or
eating a meal.
My friend has a Body Fat Analyser made by another manufacturer.
When I used it I found that I got a different body fat reading. Why is this?
Different Body Fat Analysers take measurements around different parts of the body
and use different mathematic algorithms to calculate the percentage of body fat.
The best advice is to not make comparisons from one device to another, but to use
the same device each time to monitor any change.
How do I interpret my body fat and water percentage readings?
Please refer to the Body Fat and Water tables included with the product. They will
guide you as to whether your body fat and water reading falls into a healthy category
(relative to your age and sex).
What should I do if my body fat reading is very 'high?
A sensible diet, fluid intake and exercise program can reduce your body fat
percentage. Professional medical guidance should always be sought before
embarking on such a program.
Why are the body fat percentage ranges for men and women so different?
Women naturally carry a higher percentage of fat than men, because the make-up of
the body is different being geared towards pregnancy, breastfeeding etc.
What should I do if my water percentage reading is 'low'?
Ensure that you are regularly taking sufficient water and work towards moving your
fat percentage into the healthy range.
Why should I avoid using the Body Analyser Scale whilst pregnant?
During pregnancy a woman's body composition changes considerably in order to
support the developing child. Under these circumstances, body fat percentage
readings could be inaccurate and misleading. Pregnant women should therefore only
use the weight function.
ADVICE FOR USE AND CARE • Always weigh yourself on the same scale placed on
the same floor surface. Do not compare weight readings from one scale to another
as some differences will exist due to manufacturing tolerances. • Placing your
scale on a hard, even floor will ensure the greatest accuracy and consistency. • It
is recommended that you measure at the same time of the day, preferably early
evening before a meal for the most consistent results. • Your scale rounds up or
down to the nearest increment. If you weigh yourself twice and get two different
readings, your weight lies between the two. • Clean your scale with a damp cloth.
Do not use chemical cleaning agents. • Do not allow your scale to become saturated
with water as this can damage the electronics. • Treat your scale with care - it is
a precision instrument. Do not drop it or jump on it. • Caution: the platform may
become slippery when wet.
TROUBLESHOOTING GUIDE • You must have bare feet when using body fat and
total body water measurements. • The condition of your skin on the bottom of your
feet can affect the reading. To get the most accurate and consistent reading, wipe
your feet with a damp cloth, leaving them slightly moist before stepping on the scale.
WARNING INDICATORS
Lo
Replace battery.
O-Ld Weight exceeds maximum capacity.
Err2 Out of range, incorrect operation or poor feet contact.
