Safety instructions
Please read these operating instructions carefully before using the
device for the first time, paying special attention to the safety infor-
mation.
This device should only be used as designated and described in
these instructions.
Please keep these instructions in a safe place for future reference.
Always include these instructions if passing the device on.
About this device
As well as measuring your weight, your Welby body fat scale+ allows you to
carry out comparative measurements of body fat, body water, muscle mass
and bone mass.
This device is not a medical product and is not intended for clinical use. Do not
use this device for medical diagnosis. It is intended solely for personal home
use. You should discuss any health concerns with a licensed health care pro-
vider.
To avoid possible harmful side effects, the following people may not use this
scale:
• Pregnant women
• Those who have fitted pacemakers
• Those who are suffering from fever
• Individuals with swollen legs or oedema
• Individuals with severe water retention or those who are
heavily dehydrated
• Children under six.
General
• Only place the scales on an firm level surface.
• Do not store the scale in a vertical position.
• Do not put weights on the scale unless you are measuring them and do not
store items on it.
• Protect the scale from moisture.
• Do not stand on the scale when your feet or body are wet. Always stand on
the center of the scale. Place your feet on the metal measuring surfaces so
the scale can measure your body fat and water.
• Do not continue using the device under any circumstances if it is damaged
as you could injure yourself.

Handling batteries properly
The device is powered by a 3 V button cell battery, size CR 2032.
• Batteries can be fatal if swallowed. If a battery is swallowed, please obtain
immediate medical assistance.
• Before inserting the battery, check that the contacts in the device and on the
battery are clean and, if necessary, please clean them.
• Only use new batteries.
• Do not use rechargeable batteries.
• Never try to recharge normal batteries. There is a risk of explosion.
• Store batteries in a cool, dry place. Strong direct heat can damage batteries.
Therefore, never place the device on sources of heat (e.g. radiators) or in
direct sunlight.
• Never throw batteries into a fire.
• If the scale is not going to be used for long periods of time, remove the bat-
teries.
• Remove dead batteries immediately from the device.
• Remove a leaking battery from the device immediately. Clean the contacts
before inserting a new battery. There is a risk of chemical burns due to bat-
tery acid.
Never carry out repairs yourself
Please note!
Never try to open and/or repair the device yourself. In the event of
a fault, contact our Service Center or another suitable professional
repair workshop.

Notes on measurements
Functionality
The body fat scale displays the percentage of muscle mass, body fat, body
water and bone mass in relation to total body weight. The standing area of
the scale has electrodes which measure body fat by means of the body’s elec-
tric resistance. Lean body tissue has a lower resistance than fatty body tissue.
The scale automatically compares the body fat measured to the person’s body
height, age, sex and total weight. This results in the body fat value.
Body fat
Too much body fat is unhealthy. What is more important is that a high body fat
level is usually accompanied by an increased blood fat level and this dramati-
cally increases the risk of various illnesses, such as diabetes, coronary artery dis-
ease, high blood pressure, etc.
However, if the body fat percentage is too low this is also unhealthy. In addi-
tion to subcutaneous fat tissue, the body also creates important fat deposits to
protect internal organs and safeguard important metabolic functions. If these
essential fat reserves are used, it can lead to metabolic disorders, for instance,
an increased risk of osteoporosis.
The normal body fat level varies with age and gender. The normal value for
women is around 10% higher than for men. As we get older, our bodies break
down muscle mass and this increases the body fat level.

Body water
About 60% of an adult’s body is made up of water. This varies according to
certain factors: older people have a lower water level than younger people,
and men have a higher water level than women. The difference between men
and women is based on women’s higher body fat mass. As the majority of the
body water is found in the fat-free mass (73% of the fat-free mass is water) and
the water content of fat tissue is naturally very low (around 10% of fat tissue is
water), when the body fat ratio is high the body water ratio falls automatically.
A 5% loss of water can reduce body energy by 20–30%. Drink at least 8 cups
of liquid every day.
Normal percentage of body water
Female Male
Child > 58 > 60
Adult > 52 > 58
Athlete > 56 > 60
In general, athletes have 5% more body water. With increasing age, the amount
of water falls by around 10%.

Muscle mass
The muscle mass is the body’s motor. The most of the energy we use is con-
sumed by muscles. The muscles ensure that the body temperature is main-
tained and are the basis of our physical performance.
Checking the muscle mass is particularly important for people with weight or
fat problems. As the body needs muscles to remove excess energy reserves or
fat deposits, weight reduction can only be successful in the long term if mus-
cles are built up at the same time.

6~12 >36 >40
13~79 >30 >34
Athlete >38 >42
Athlete mode
Your scale has a special setting for well-trained and muscular people (“ath-
letes”). As muscle cells have a similar bioelectric resistance to fat cells, the scale
could interpret muscles as fat. This problem only occurs if the muscle mass is
large; if a person has a normal range of muscles the scale do not measure this
as fat.
The athlete mode prevents this incorrect interpretation. In this mode, the actual
body fat values are measured using a different mathematical formula.

10
Reasons for imprecise measurement results
The analysis is based on measuring electrical body resistance. Eating and drink-
ing habits over the day and your personal lifestyle affect the level of water. This
is noticeable from variations in the measurements displayed.
In order to achieve an analysis result that is as precise and repeatable as pos-
sible, ensure that the measurement conditions are the same because this is the
only way to observe changes over a longer period of time. You will receive the
most reliable measurement results if you always take the measurement in the
morning after waking up. This is the best way of detecting a trend.
Other factors can also affect the level of water:
• After bathing you may get a result where the displayed body fat level is too
low and the body water level too high.
• The result may be higher after a meal.
• Women experience differences as a result of their menstrual cycle.
• A loss of body water as a result of illness or physical exertion (sport). After
sporting activity you should wait 6 to 8 hours before taking another meas-
urement.
Variances or implausible results can occur for:
• Individuals with osteoporosis
• Individuals being treating with dialysis
• Individuals taking cardiovascular medicine
• Thick calluses on the feet
• Athletes who do over 10 hours of intensive training per week and have a
resting pulse of less than 60 beats per minute
• Top athletes and body-builders
• Young people under 17 years of age
The athlete mode is designed for individuals who train frequently and/or inten-
sively. Please see “Athlete mode“on page 9).

Inserting batteries
The scale is operated with a 3 V button cell battery, size CR 2032.
The battery is inserted in the device at the factory. In order to activate the device,
pull the flap of the protective foil to remove it from the battery compartment.
To remove or change the battery, open the battery compartment cover un-
der the device.
When inserting the battery, ensure that the +/− terminals are correct (with
the positive pole facing up).
When the battery has been inserted and the battery compartment is closed,
place the scale on the floor and place a little weight onto the scale. Wait until
the scale switch off. The scale is now calibrated.
If the screen shows “Lo” or the display’s intensity falls, the battery must be
replaced.
Only insert one new battery.
Do not expose a device containing a battery to direct heat or sunlight. For
example, do not place the device on a radiator.
If the scale is not going to be used for long periods, remove the battery.
Please also note the section “Handling batteries properly“on page 5 to ensure
you use the batteries correctly.
