- Do not throw batteries into fire. Explosion hazard!
General notes
- The unit is for personal use only and is not intended for medical or commercial applications.
- Note that technical tolerances mean that results may vary, because the scale is not calibrated for professional medical use.
- The capacity of the scale is 180 kg (396 lb). For weight measurement and bone mass measurement, the results are shown in 100 g increments (0.2 lb).
- The measuring results of the body fat, body water and muscle percentage are shown in 0.1 % increments.
- The caloric requirements is specified in steps of 1 kcal.
- When supplied to the customer, the scale is set to weigh and measure in “kg” and “cm”. You can change the unit settings during initial use of the app.
- Place the scale on a firm level floor; a firm floor covering is required for correct measurement.
- Protect the unit against hard knocks, moisture, dust, chemicals, major temperature fluctuations and heat sources which are too close (stoves, heating radiators).
Storage and maintenance
The accuracy of the measurements and service life of the device depend on its careful handling:
IMPORTANT
- The unit should be cleaned occasionally. Do not use abrasive detergents and never immerse the unit in water.
- Ensure that no liquid gets on the scale. Never dip the scale into water. Never wash it under running water.
- Do not place aray objects on the scale when it is not being used.
- Protect the unit against hard knocks, moisture, dust, chemicals, major temperature fluctuations and heat sources which are too close (stoves, heating radiators).
- Do not press the buttons using excessive force or with pointed objects.
- Do not expose the scale to high temperatures or strong electromagnetic fields (e.g. mobile phones).
lnformation
The measuring principle
This scale operates according to the B. I.A. principle (bioelectric impedance
analysis). This enables the measurement of physical relationships 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 calculating
constants and individual parameters such as age height, gender and degree of
activity.
Muscle tissue and water have good electrical conductivity I and therefore
lower resistance. Bones and fatty tissue, on the other handt have low
conductivify as fat cells and bones conduct hardly any current as a result of
their very high resistance.
Please be aware that values obtained from the diagnostic scale represent only
an approximation of actual analyticat medical data. Only a specialist
physician can accurately determine body fat, body water. muscle percentage and
bone structure using medical procedures (e.g. computed tomography).
General tips
-
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.
-
Important for the measurement: only measure body fat when barefoot and with the soles of the feet slightly moist.
Completely dry soles can result in unsa1isfactory measurements due to inadequate conductivity. -
Stand still and upright during the measurement.
-
Wait a few hours after unaccustomed physical activity.
-
Wait approx. 15 minutes after getting up in the morning to allow the water in the body to distribute.
-
Remember that only long-teim trends are important. Short-term changes in weight within a few days are usually caused by a lloss of fluid. Body water plays an important role towards our general wellbeing.
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 (affecting the heart and vascular system),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).

Initial use of the scale
Inserting batteries
Remove the batteries from the protective packaging and insert the batteries into the scale ensuring that the battery polarity is correct. If the scale does not function, remove the batteries completely and reinsert them.
Setting up the scale
Place the scale on a firm level floor; a firm floor covering is required for
correct
measurement.
Initial use with the app
- Search Belter Body Fat Scale from Baidu Assistant in Android System
- Search Belter Body Fat Scale in IOS App Store
The following settings must be set or entered in the app:
| User data | Parameters |
|---|---|
| Body height | 100 to 220 cm (3′ 3.5″ to 7′ 2.5″) |
| Birthday | 10 to 100 Years |
| Sex | male,female |
| Degree of activity | Normal worker or Athlete |
- Assign the user when requested to do so by the app.
For automatic personal recognition, the first measurement must be assigned to your personal user data.
Follow the app instructions for this. Step onto the scale with bare feet and ensure that you are standing still with equal weight distribution and with both legs on the electrodes.
Taking measurements
Place the scale on a firm level floor; a firm floor covering is required
for correct measurement.
When using on carpet, affix the additional feet for carpet.
Weighing, carrying out diagnostics
Step onto the scale with bare feet and ensure that you are standing still with equal weight distribution and with both legs on the electrodes.
Note: There must be no skin contact between your feet, legs, calves or
thighs. Otherwise the measurement cannot be performed correctly.
Note: The measurement result will be incorrect if the measurement is
carried out with socks on.
The scales begin weighing immediately. First, the weight is displayed.
Whilst the further parameters are being measured an “oooo” appears.
Your measured weight is displayed shortly after this.
If a user has been assigned, the BMI, body fat, water, muscle, bone, and BMR
are shown. This is the case if the initials are shown.
The following appears:
- Weight in kg with BMI
- Body fat in % with interpretation of Fat
- Body water in % Water
- Muscle percentage in % Muscle
- Bone mass in kg Bone
- Basal metabolic rate in kcal (BMR)
- Visceral in number
- Capacity:5kg-180kg
If the user is not recognised, only the weight can be shown and no initials appear “ ”
Only weight measurement
Now step on the scale wearing shoes. Stand still on the scale with your weight
distributed evenly between both legs. The scale immediately begins to measure
your weight.
The weight is shown and “ ” on the LCD
If a user has been assigned then the BMI, BMR and AMR are displayed.
If the user is not recognised, only the weight can be shown and no initials
appear “ “.
Note: Only the measurements displayed on the scale may be used for further observations.
Switching off the scale
The scale will then switch itself off automatically.

| 70-100 | <18% | 18-23% | 23,1- 28% | >28,1 % |
Woman
| Age | low | normal | high | very high |
|---|---|---|---|---|
| 10-14 | <16% | 16-21% | 21,1- 26% | >26,1 % |
| 15-19 | <17% | 17-22% | 22,1- 27% | >27,1 % |
| 20-29 | <18% | 18-23% | 23,1-28% | >28,1 % |
| 30-39 | <19% | 19-24% | 24,1-29% | >29,1 % |
| 40-49 | <20% | 20-25% | 25,1-30% | >30,1% |
| 50-59 | <21% | 21-26% | 26,1-31 % | >31,1% |
| **** | <22% | 22-27% | 27,1- 32% | >32,1 % |
| 70-100 | <23% | 23-28% | 28,1- 33% | >33,1% |
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 percentage
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 percentage.
This scale is unsuitable for measuring body water in order to draw medical
conclusions concerning agerelated water retention, for example. 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% |
| 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 % |
| 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% |
Bone mass
Like the rest of our body, our bones are subject to the natural development,
degeneration and ageing processes. Bone mass increases rapidly in childhood
and reaches its maximum between 30 and 40 years of age. Bone mass reduces
slightly with increasing age. You can reduce this degeneration somewhat with
healthy nutrition (particularly calcium and vitamin D) and regular exercise.
With appropriate muscle building, you can also strengthen your bone structure.
Note that this scale will not show you the calcium content of your bones, but
will measure the weight of all bone constituents (organic substances,
inorganic substances and water). Little influence can be exerted on bone mass,
but it will vary slightly within the influencing factors (weight, height, age,
gender). no recognised guidelines or recommendations relating to bone mass
measurement.
ATTENTION:
Please do not confuse bone mass with bone density.
Bone density can be determined only by means of a medical examination (e.g.
computer tomography, ultrasound). It is therefore not possible to draw
conclusions concerning changes to the bones and bone hardness (e.g.
osteoporosis) using this scale.
The basal metabolic rate (BMR) is the amount of energy required by the body at
complete rest to maintain its basic functions (e.g. while lying in bed for 24
hours). This value largely depends on weight, height and age.
It is displayed on the diagnostic scale in kcal/day units using the
scientifically recognized Harris-Benedict formula.
Your body requires this amount of energy in any case and it must be
reintroduced into your body in the form of nutrition. If you take on less
energy over the longer term, this can be harmful to your health.
Results in relation to time
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 contain body water).
Power off
When the scale stays at 0.0kg and no operating on it, it it will get into sleep mode in 35S±3S.
