Safety notes
-
kers). Otherwise their function could be impaired.
• Do not use during pregnancy. Inaccurate measurements may be caused by the amniotic fluid.
• Caution! Do not stand on the scale with wet feet and do not step on the scale when its surface is wet –
danger of slipping!
• Keep children away from packing materials (danger of suffocation).
General notes
• Scale only operates if there is light!
•
The unit is for personal use only and is not intended for medical or commercial applications.
•
Please note that technically related measuring tolerances are possible, as the scale is not calibrated for
professional medical applications.
• Ages 10 ... 100 years and height settings from 100 ... 220 cm (3-03”–7-03”) can be preset. Load capaci-
ty: max. 150 kg (330 lb, 24 st). Graduation in steps of 100 g (0.2 lb/ 1/4 st) or steps of 0.1%.
• On delivery the scale is set to the units “cm” and “kg”. A switch located on the back of the scale enables
you to change to “inch”, “pound” and “stones” (lb, St).
• Place the scale on a firm level floor; a firm floor covering is required for correct measurement.
• The scale should be cleaned occasionally with a damp cloth. Do not use abrasive detergents and never
immerse the scale in water.
• Protect the scale against hard knocks, moisture, dust, chemicals, major temperature fluctuations and
heat sources which are too close (stove, heating radiators).
• Repairs may only be carried out by Beurer customer service or authorized dealers. Before submitting
any complaint, first check the batteries and replace them if necessary.

3. Information on the diagnostic scale
The measuring principle of the diagnostic scale
This scale operates according to the B.I.A. principle (bioelectric impedance analysis). This enables physi-
cal relationships to be measured within seconds by means of an undetectable, completely harmless
electric current. The body fat percentage and other physical relationships in the body can be determined
by measuring the electrical resistance (impedance), and the inclusion in a calculation of constants and in-
dividual parameters (age, height, gender, degree of activity).
Please be aware that values obtained from the diagnostic scale represent only an approximation of actual
analytical medical data.
General tips
•
If possible, always weigh yourself at the same time of day (preferably in the morning), after using the toi-
let, on an empty stomach and unclothed, in order to achieve comparable results.
•
Important for the measurement: body fat can only be measured when barefoot and with the soles of the
feet slightly moist. Completely dry soles can result in unsatisfactory measurements due to inadequate
conductivity.
•
Stand still during the measurement.
•
Wait a few hours after unaccustomed strenuous activity.
•
Wait approx. 15 minutes after getting up in the morning to allow the water in the body to distribute.
Limitations
When measuring body fat and other values, deviating and implausible results may occur in:
•
children under approx. 10 years,
•
competitive athletes and body builders,
•
pregnant women,
•
persons with fever, undergoing dialysis treatment or with symptoms of edema or osteoporosis,
•
persons taking cardiovascular medication,
•
persons taking vascular dilating or vascular constricting medication,
•
persons with considerable anatomic deviations of the legs in relation to total body size (length of the legs
considerably shortened or lengthened).
4. Operation
The scale is solarpowered. It requires sufficient light to operate. If the lighting
conditions are sufficient, a flashing sun symbol or “0.0” appears in the display.
If the lighting conditions are too dark, no measurement can be taken. Place the
*d
scale somewhere with more light.

ment.
Step on the scale. It immediately begins to measure. Stand still with your weight distributed equally on both
legs. If the display appears continuously, the measurement has finished.
If you step off the weighing area, the scale switches off after a few seconds.
4.2 Setting user data
To measure your body fat percentage and other physical data, you must enter your personal user parame-
ters.
The scale has 10 memory positions in which you and other members of your family can save and recall
personal settings.
Switch on the scale (tap the weighing area). Wait until the display shows “0.0”.
9
Then press “set”. The first memory position will appear flashing on the display. Now you can enter the fol-
lowing settings:
Memory position 1 to 10
Body size 100 to 220 cm (3‘-03“ to 7‘-03“)
10 to100 years
Sex
male (
), female ( )
1 to 3
You can enter the relevant settings with short or long pressure on the up button
or down button .
Confirm the settings in each case by pressing “set”.
The values set are displayed again one after another until “0.0” is shown in the display. The scale is then
ready to use or automatically switches off after a few seconds.
Selection of the degree of activity must refer to the medium and long term.
Degree of activity Physical activity
1 None.
A small amount of light physical effort (e.g. short walks, light garden work, gymna-
2
stic exercises).
3 Physical effort for 30 minutes at least 2 to 4 times a week.
4.3 Taking measurements
After all parameters have been entered, you can now measure your weight, body fat and the other data.
•Press the “set” button and select the memory space where you would like to save your basic personal
data by pressing the “up”
or “down” button the appropriate number of times. These are displa-
yed in sequence until “0.0” and the selected gender appear.
•Step onto the scale barefoot and make sure you’re standing on both electrodes. First your body weight
is determined and displayed.

A lower value is often found in athletes. Depending on the type of sports, training intensity and physical
constitution, values may result which are below the recommended values stated.
It should, however, be noted that there could be a danger to health in the case of extremely low values.
Body water:
The body water percentage is normally within the following ranges:
Man Woman
poor good
poor good
10-100 <50% 50-65% >65
10-100 <45% 45-60% >60
Body fat contains relatively little water. Therefore persons with a high body fat percentage have body wa-
ter percentages below the recommended values. With endurance athletes, however, the recommended
values could be exceeded due to low fat percentages and high muscle percentage.
Body water measurement with this scale is not suitable for drawing medical conclusions, for example con-
cerning age-related water retention. If necessary ask your physician.
Basically, a high body water percentage should be the aim.
Body weight / Body mass index
The body mass index (BMI) is a number that is often called upon to evaluate body weight. The number is
calculated from body weight and height, the formula is – body mass index = body weight : height². The
measurement unit for BMI is [kg/m²].

Note that with very muscular physiques (body builders), the BMI interpretation will show overweight.
The reason for this is that no account is taken of well above average muscle mass in the BMI formula.
Results in relation to time
Note that it is only the long-term trend which counts. Short period fluctuations in weight over a few days
are mostly the result of a loss of fluid.
The interpretation of the results will depend on changes in your: overall weight and body fat, body water
and muscle percentages, as well as on the period during which these changes take place. Rapid changes
within days must be distinguished from medium term changes (over weeks) and long term changes
(months).
A basic rule is that short term changes in weight almost exclusively represent changes in water content,
whereas medium and long term changes may also involve the fat and muscle percentages.
• If your weight reduces over the short term, but your body fat percentage increases or remains the same,
you have merely lost water – e.g. after a training session, sauna session or a diet restricted only to rapid
weight loss.
• If your weight increases over the medium term and the body fat percentage falls or stays the same, then
you could have built up valuable muscle mass.
If your weight and body fat percentage fall simultaneously then your diet is working – you are losing fat
mass. Ideally you should support your diet with physical activity, fitness or power training.
6. Incorrect measurement
If the scale detects an error during weighing, „FAT ” or “ ” appears in the display.
If you step onto the scale before “0.0” appears in the display, the scale will not operate properly.
Possible causes of error:
Remedy:
– The maximum load-bearing capacity of 150 kg
– Only weigh the maximum permissible weight.
(330 lbs) was exceeded.
– The electrical resistance between the electrodes
– Repeat weighing barefoot. Slightly moisten the
and the soles of your feed is too high (e.g. with
soles of your feet if necessary. Remove the cal-
heavily callused skin).
luses on the soles of your feet if necessary.
– Your body fat lies outside the measurable range
– Repeat weighing barefoot.
(less than 5 % or greater than 80 %).
– Slightly moisten the soles of your feet if neces-
sary.
– No response.
– Cover solar cells and apply pressure to the plat-
form for approx. 5 seconds. Repeat weighing with
sufficient light.
