4.2 General notes
- Please note that measuring tolerances are possible due to technical reasons because the scale has not been calibrated.
- Ages 10 to 100 years and height settings from 100 to 220 cm (3-03″ to 7-03″) can be preset. Load capacity: max. 150 kg (330 lb, 24 st).
- Result in steps of 100g (0.2 lb, 1/4 st). Measurements of body fat, body water, and muscle density in steps of 0.1%.
- When supplied to the customer, the scale is set to weigh and measure in “kg” and “cm”. On the back of the scale, there is a toggle button where you can select “pounds” (lb) and “stones” (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 that are too close (stove, heating radiator).
- Repairs may only be carried out by customer service or authorized dealers. Before submitting any complaint, first check the batteries and replace them if necessary.
Operation
5.1 Batteries
If present, pull the battery insulating strip off the battery compartment
cover or remove the battery’s protective film and insert the battery according
to the polarity. If the scale fails to operate, remove the battery completely
and insert it again. Your scale is equipped with a “replace battery”
indicator. When the scale is operated with a battery that is too weak, “Lo”
appears in the display field and the scale automatically switches off. In this
case, the batteries must be replaced (1 x 3 V lithium battery CR2032).
5.2 Measuring weight only
Step onto the scale. Stand still with your weight distributed equally on both
feet. The scale begins to take measurements straight away. If the display
appears continuously, the measurement has finished. If you step off the
weighing area, the scale switches off after a few seconds.
5.3 Setting user data
To measure your body fat percentage and other physical data, you must enter
your personal user parameters. The scale has 10 memory positions in which you
and other members of your family can save and recall personal settings. Please
note that the memory begins with 1. Switch on the scale (tap the standing
surface). Wait until the display shows “0.0”. Then press “SET”. The first
memory position will appear flashing on the display. Now you can enter the
following settings:
| Memory position | 1 to 10 |
|---|---|
| Age | 10 to 100 years |
| Body size | 100 to 220 cm (3‘-03“ to 7‘-03“) |
| Sex | male |
| Degree of activity | 1 to 5 |
Changing the values: Press the button or .
Confirming the entries: Press the “SET” button.
The values that you have set here are then displayed again one after another.
The scale then switches itself off automatically at this point.
Degrees of activity
Selection of the degree of activity must refer to the medium and long term.
| Degree of activity | Physical activity |
|---|---|
| 1 | None. |
| 2 | Low: A small amount of light physical effort (e.g. short walks, light |
garden work, gymnastic exercises).
3| Medium: Physical effort for 30 minutes at least 2 to 4 times a week.
4| High: Physical effort for 30 minutes at least 4 to 6 times a week.
5| Very high: Intensive physical effort, intensive training, or hard
physical work for at least one hour daily.
After all, parameters have been entered, you can now measure your weight, body
fat, and other data.
5.4 Taking measurements
- 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 displayed in sequence until “0.0” and the selected gender appear.
- Step onto the scale with bare feet and make sure that you are standing still with equal weight distribution. Stand on the stainless steel electrodes with both feet.
- Remain on the scale and avoid moving; it is now performing your body fat and body water analysis. This may take a few seconds.
Note: Your feet, legs, calves, and thighs must not touch each other.
Otherwise, the measurement cannot be performed correctly.The scale immediately
begins to measure your weight.
The following data are displayed:
- Bodyweight in kg
- Body fat percentage FAT in %
- Water percentage BW in %
- Muscle percentage MUS in %
- BMI
- Now, all measured values are displayed consecutively and the scale switches off.
5.5 Tips for using the scale
Important when measuring body fat/body water/muscle percentage/bone
content:
- If possible, always weigh yourself at the same time of day (preferably in the morning), after using the toilet, on an empty stomach and unclothed, in order to achieve comparable results.
- The measurement may only be carried out while barefoot and it is helpful if the soles of your feet are slightly damp. Completely dry soles can result in unsatisfactory results, as they have insufficient conductivity.
- Stand still during the measurement.
- Wait several hours after unusually strenuous activity.
- Wait approx. 15 minutes after getting out of bed so that the water in your body can be distributed.
- Remember that only long-term trends are important.
- Short-term changes in weight within a few days are usually caused by a loss of fluid.
- Body water plays an important role in our general well-being.
The measurement is not reliable for:
- Children under approx. 10 years of age.
- Competitive athletes, bodybuilders.
- Pregnant women.
- Persons with fever, undergoing dialysis, with symptoms of edema or osteoporosis.
- Persons taking cardiovascular medication.
- Persons taking vasodilating or vasoconstricting medications.
- Persons with substantial anatomical deviations in the legs relative to their total height (leg length considerably shorter or longer than usual).
The measuring principle
This scale works on the principle of B.I.A. (bioelectrical impedance
analysis). This involves the calculation of body content within seconds, using
a current that is not noticeable, is completely non-hazardous, and does not
pose any risk.
When this measurement of the electrical resistance (impedance) is considered
alongside constants and/ or individual values (age, height, gender, activity
level), the body fat percentage and other variables in the body can be
calculated. Muscle tissue and water conduct electricity well and therefore
have a lower resistance. In contrast, bones and fat tissue have low
conductivity as the fat cells and bones are barely able to conduct the current
due to very high levels of resistance.
Please note that the values calculated by the diagnostic scale only represent
an approximation of the actual medical analytical values for the body. Only a
specialist doctor can precisely establish the body fat, body water, muscle
percentage, and bone structure using medical methods (e.g. computer
tomography).

---|---|---|---|---
10-14| <16%| 16-21%| 21,1-26%| >26%
15-19| <17%| 17-22%| 22,1-27%| >27%
20-29| <18%| 18-23%| 23,1-28%| >28%
30-39| <19%| 19-24%| 24,1-29%| >29%
40-49| <20%| 20-25%| 25,1-30%| >30%
50-59| <21%| 21-26%| 26,1-31%| >31%
60-69| <22%| 22-27%| 27,1-32%| >32%

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
| Age | poor | good | very good |
|---|---|---|---|
| 10-100 | <50% | 50-65% | >65 |
Woman
| Age | poor | good | very good |
|---|---|---|---|
| 10-100 | <45% | 45-60% | >60 |
Body fat contains relatively little water. Therefore persons with a high body
fat percentage have body water percentages below the recommended values. With
endurance athletes, however, the recommended values could be exceeded due to
low-fat percentages and high muscle percentages. Body water measurement with
this scale is not suitable for drawing medical conclusions, for example
concerning age-related water retention. If necessary ask your physician.
Basically, a high body water percentage should be the aim.
Muscle percentage:
The muscle percentage (%) is normally within the following ranges:
Man
| Age | low | normal | high |
|---|---|---|---|
| 10–14 | <44% | 44–57% | >57% |
| 15–19 | <43% | 43–56% | >56% |
| Age | low | normal | high |
| --- | --- | --- | --- |
| 20–29 | <42% | 42–54% | >54% |
| 30–39 | <41% | 41–52% | >52% |
| 40–49 | <40% | 40–50% | >50% |
| 50–59 | <39% | 39-48% | >48% |
| 60–69 | <38% | 38–47% | >47% |
| 70–100 | <37% | 37–46% | >46% |
Woman
| Age | low | normal | high |
|---|---|---|---|
| 10–14 | <36% | 36–43% | >43% |
| 15–19 | <35% | 35–41% | >41% |
| Age | low | normal | high |
| --- | --- | --- | --- |
| 20–29 | <34% | 34–39% | >39% |
| 30–39 | <33% | 33–38% | >38% |
| 40–49 | <31% | 31–36% | >36% |
| 50–59 | <29% | 29–34% | >34% |
| 60–69 | <28% | 28–33% | >33% |
| 70–100 | <27% | 27–32% | >32% |
The body mass index (BMI
The body mass index (BMI) is a number that is often called upon to evaluate
body weight. The figure is calculated from body weight and height. The formula
is: body mass index = body weight: height². The measurement unit for BMI is
[kg/m²]. According to the BMI, weight is classified for adults (20 years and
over) using the following values:
| Category | BMI |
|---|---|
| Underweight | Severely underweight |
| Underweight | 16-16.9 |
| Slightly underweight | 17-18.4 |
| Normal weight | |
| Overweight | Overweight |
| Obese (overweight) | Class I obesity |
| Class II obesity | 35-39.9 |
| Class III obesity | ≥ 40 |
Results in relation to time
Note: Remember that only long-term trends are important. Short-term
fluctuations in weight over a few days are usually 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. Sudden 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. This way you can increase your muscle percentage over the medium term.
- Body fat, body water, or muscle percentages should not be added (certain elements of muscle tissue also con-
tain body water).
Cleaning and care of the unit
The unit should be cleaned occasionally. Clean using a damp cloth, to which
you can apply a little detergent if necessary.
IMPORTANT:
- Do not use aggressive solvents or cleaning agents!
- Never immerse the unit in the water!
- Do not wash the unit in a dishwasher!
