INTENDED USE:
This product is a device for estimating body composition by measuring the local bio-impedance value of the
user’s body. Used to measure body weight, body fat, body water, muscle mass, bone mass, BMI and basal
metabolism, wireless transmission.
• This scale is not suitable for people with pacemakers or other medical implants. The indication of body fat may
be inaccurate in the event of diabetes or other medical/physical conditions. The same applies to highly trained
sportsmen.
• The body fat measurement algorithm is calibrated for individuals between the ages of 6 and 80 years old.
Users outside of this age range can only use the weight measurement feature.
• The device uses Bioelectrical Impedance Analysis (BIA) and it may cause a weak current while taking
measurement. So it’s not recommended for pregnant women use.
• Any treatment or diet for overweight or underweight requires qualified advice from appropriate specialists
(doctor, dietician). The values determind with the scale can be of help.
• Risk of tilting! Never place the scales on an uneven surface. Never step onto just one corner of the scale. While
weighing, never stand on one side or on the edge of the scale.
• Danger of slipping! Never step onto the scale with wet feet. Never step onto the scale while wearing socks.
• Use the device only as directed by the instruction manual. In the event of misuse, all warrantees become null
and void.
• The scale is manufactured for home or personal use. It is not intended for commercial use in hospitals or other
medical facilities.
• Do not use the device if it does not work properly, if it has been dropped, dropped into water or damaged.
• The scale has a measuring range up to 180 kg/396 lbs. Do not overload the scale.
• Place the scale on a firm level surface. Soft, uneven surfaces are unsuitable for measurement and lead to
wrong results.
• Place the scale in a location where neither extreme temperatures nor extreme humidity are present.
• Please handle the scale with care. Avoid shocks and vibrations of the scale. Do not drop it.
• Stand carefully on the scale. Do not hop or jump on the treated surface, as this may damage the weighing
mechanism.
• Do not attempt to disassemble the device. Otherwise the warranty will become void. This device does not
contain any parts that can be serviced or replaced by the user.
• In the event of malfunctions, do not proceed with any unauthorised repair of the device. Otherwise, this will
void any warranty claims. Have repairs performed only by an authorised service centre.

Requirements for correct measurement results
• Always weigh yourself in the same conditions.
• Measure at the same time of day.
• Stand upright and calm.
• It is best to take the measurement in the morning, after showering or bathing, with dry foot.
With the results of the measurement, when carried out consistently, a reliable control of the development of the body
weight is possible.
Getting started - Charging the scale
Use a 5V mains adapter with an output current of 1A. Connect the supplied USB charging cable to the adapter and to
the USB-C port
3
of the device (The USB-C charging cable is included in the packaging). There is a battery icon to
indicate the percentage when charging.
Initialise scale
Make sure that the scale is on firm and level ground
7
. If you want to weigh yourself, but have moved the scale
immediately before, you must first initialise the scale. Briefly press the middle of the scale surface with your bare feet.
The display will show “0.00”. When the scale has turned off, it is ready for the “step-on” function. If the scale has not
been moved before-hand, this process is omitted.

Body weighing and analysis
• Stepping onto your monitor with socks or footwear on will result in an inaccurate measurement.
• If the posture is wrong, such as squatting, knees bent, the bare feet are not on the electrodes, the
measurement will be inaccurate.
1.
Step onto the scale with bare feet, wrap your hands around the electrodes on both sides of the handle
, and pull
up the handle until your arms are level with your chest.
2. Stand still and the final weight flashes on the display.
3. Now you can select the user profile by pressing button
or button
3
. If Guest user is selected, only body weight
will be measured
4. Keep holding the handle and your body metrics will be gathered in around 3 seconds.
5. When you see “Gathering body metrics...” appears, this is to indicate that the data is being analyzed. Please keep
your post during this period. Once the process is completed, the heartrate, current weight, ideal weight, goal weight,
BMI, body fat, physical age, body water, muscle mass and fat mass are displayed one after the other.
6. After the first measurement, the scale will be able to automatically recognize you based on the previous weight. If
you measure offline, you will still see the 10 data points of your results. The data will be synchronized again once
you reconnect to the app.

How a body analysis scale works
medisana body analysis scale is tested by the
Bioelectrical Impedance Analysis (BIA) method. The
principle of Bioelectrical Impedance Analysis (BIA) is
to apply weak current to body through the electrodes
on the surface of scale, and use the theory that water
in the body conducts electricity while fat does not,
thereby measure the body’s resistance. Then based
on sample data, the body fat content is calculated by
comparison.
Low-frequency current: obtain extracellular intelligence; high-frequency current: gain extracellular and
Intracellular intelligence
Fatty tissue: Poor electrical conductivity
Non-fatty tissue: Better conductivity with more electrolyte
The body is divided into fatty tissue and non-fatty tissue according to above principle, and the resistance feedback
of the two is also different. The body analysis scale calculates the proportion of different components of the body
through data feedback and calculation.
Heart
rate
Heart rate refers to the number of beats per minute of the heart. The normal
heart rate range varies depending on individual differences.
Body
weight
Body weight refers to "the sum of all organs and metabolites in the body",
which includes bones, muscles, fat, blood, internal organs, metabolic waste,
and many other indicators. However, the largest proportion among them is
water.
BMI
Body Mass Index (BMI) is the relationship between weight and height, body
fat and health risk.
BMI =
Body weight (kg)
Body height (m)

BMR
BMR refers to the body’s basal metabolic rate, which is the minimum rate of
energy expenditure required by the body to sustain basic life activities in a
quite state. BMR is mainly affected by factors such as age, gender, height,
weight and muscle mass, and it is the main source of the body’s daily energy
expenditure.
Body fat
Body fat percentage refers to the ratio of body weight in fatty tissue.
Body fat (
%
) =
Body fat weight (kg)
x 100%

• Please ensure that the polythene packing is kept away from the reach of children!
Risk of suffocation!
• The percentage of body fat, body water, muscle mass, bone weight, as well as body mass
index (BMI), the values of the basal metabolic rate (KCAL) are to be considered only as
approximate data. For any further information, refer to a doctor or to a dietician.
• Self-measuring means control, it does not mean diagnosis or treatment. Any unusual levels
should always be discussed with your doctor. Under no circumstances must you change the
dose of medicines prescribed by your doctor.

health status, reflecting the level of the physical health relative to
their actual age.

Muscle mass
Muscle mass refers to the total amount of muscle in the human
body, including skeletal muscle, myocardial muscle, and smooth
muscle. Muscle is one of the main metabolic tissues in the
human body, which plays an important role in maintaining Basal
Metabolic Rate, improving body stability, and promoting fat
decomposition.
Subcutaneous
fat mass
Human adipose tissue can be categorized into different types
based on its location, including visceral fat, subcutaneous fat,
and intermuscular fat. Subcutaneous fat specifically refers to the
fat stored beneath the skin, particularly in the abdomen area and
regions with well-developed muscles.
Protein
Protein quality refers to the protein content in the body tissue.
They are protein molecules present in the human body and are
important components of tissues, cells, and organs within the
body.
