Is electro-smog produced when heat pads / underblanket / foot warmers are used?
The term “electro-smog“ denotes ...
The term “electro-smog“ denotes electrical and magnetic fields with
various characteristics (e.g. pulsed in the case of mobile telephones)
and various frequencies (e.g. 50Hz when mains operated). Electrical
and magnetic fields always occur when electrically operated products
are used and also due to the domestic electrical installation.
electrical and magnetic fields that occur when heat pads, foot warmers,
heated underblankets and heated overblankets are used are far below the
limits recommended by the World Health Organisation (WHO) and
stipulated by German law:
Electrical field strength: max. 5000 V/m
Magnetic field strength: max. 80 A/m
Magnetic flux density: max. 100 mikrotesla
Why does my heat pad / foot warmer / electric underblanket / electric overblanket not get hot enough?
Heat pad: Depending on the heat pad model ...
Depending on the heat pad model and method of use, it can sometimes
take up to 15 minutes after it has been switched on before the heat pad
becomes warm to the touch at the highest setting. The maximum final
temperature is reached after approx. 30 minutes at the earliest.
Depending on where it is placed, it can sometimes
take up to 15 minutes after it has been switched on before the foot
warmer becomes warm to the touch at the highest setting. Place the foot
warmer on a carpet or similarly insulating underlay so that it will warm
The maximum final temperature is reached after approx. 30 minutes at the
Depending on the underblanket model and the surrounding conditions
(room temperature, mattress, bedclothes) it can sometimes take up to 30
minutes after it has been switched on before the underblanket becomes
warm to the touch at the highest setting.
In order to prevent heat loss, the electric underblanket must be
completely covered. The maximum final temperature is reached after
approx. 60 minutes at the earliest
Depending on the overblanket model and the room temperature, it can
sometimes take up to 15 minutes after it has been switched on before
the overblanket becomes warm to the touch at the highest setting.
The maximum final temperature is reached after approx. 30 minutes at the earliest.
What should be noted with cardiac pacemakers?
The electrical and magnetic fields emitted ...
The electrical and magnetic fields emitted by this product can sometimes interfere with the function of your pacemaker.
However, they are far below the limits:
Electrical field strength: max. 5000 V/m
Magnetic field strength: max. 80 A/m
Magnetic flux density: max. 100 mikrotesla
Please consult your doctor and the manufacturer of your pacemaker before using this product.
How high is the final temperature?
The maximum temperature that can be reached depends ...
The maximum temperature that can be reached depends on many factors,
including the product (heat pad, foot warmer, electric underblanket,
electric overblanket), the model (e.g. with or without automatic cutoff)
and the room temperature.
It is therefore possible only to give average values obtained under
standardised conditions at a room temperature of 20°C +/- 5°C.
Different measurement conditions are specified for each product.
The individual values can therefore not be compared with one another.
Heat pad: 70°C - 75°C
Foot warmer: 45°C - 50°C
Underblankets: 60°C - 65°C
Overblankets: 40°C - 50°C
Can persons with implants use body fat scales?
Body fat scales must not be used ...
- Body fat scales must not be used with electrically operated impla (e.g. cardiac pacemalers, medication pumps)
- Persons with electrically conducting implants (e.g. bone screws, hip replacements) can use the scales. However, incorrect measurements can occur because of the better electrical conductivity of the implant compared to the tissues.
Can pregnant women use a body fat scales?
The body fat scales should not ...
The body fat scales should not be used during pregnancy. Because of the amniotic fluid, incorrect measurements can occur.
Why are different weight readings obtained with measurements taken directly in succession?
Different weight readings can be caused ...
- Different weight readings can be caused by not standing still on the scales
- The scales was pushed or lifted between the measurements, there was no
correct zero setting or initialisation between the measurements
- Due to technical tolerances, there can be a difference of up to +/- 0.5 kg in the readings between two measurements
- Incorrect position on the scales, person stands a bit further forward or a bit further backward on the scales
Why are different body fat readings obtained with measurements taken directly in succession?
Fluctuating results in measurement of weight ...
- Fluctuating results in measurement of weight
- Effect of external factors such as dryer feet etc.
- Movement artefacts
- User stands differently on the electrodes from one measurement to another
What does “Quick Start“ and “Tap on“ mean?
With scales with the “Quick Start“ function, the user can...
- With scales with the “Quick Start“ function, the user can stand on the
scales directly without switching it on beforehand. The scales switches
on independently and then starts measuring when it is stepped on.
- The “Tap on“ function describes switching on the scales by tapping the
upper bowl of the scales. This means that the user has to tap on the
scales and then wait until 0.0 appears in the display. It is only
possible then to step on the scales and commence measurement.
What factors can affect the measurement of body fat?
- Anatomical variations (e.g. considerably longer or shorter leg length)
- Volume of calves and/or thighs
- Training condition of the muscles
- Bone structure
- Fat distribution in the body
- User’s state of health
- Poor contact between soles of the feet and electrodes
- Severe sweating
- Use of medications
- Oedema of the legs
- Haematomas in the legs
- Measurement after physical effort
- Measurement at different times of the day
- Fluctuating body weight
- Pregnancy (amniotic fluid)
- Metal implants
- Calloused skin on the soles of the feet
Why do I have different readings in the normal and athlete mode?
The athlete mode is an additional ...
The athlete mode is an additional function for adjusting the body fat
measurement to the individual circumstances of a user group. When
analysing body fat, several fixed parameters are specified in the
scales‘ software for calculating the proportion of body fat, along with
the actual measurement of body resistance. In the normal mode, these
constants reflect the average of the “normal population“ as obtained in
medical studies. The so-called athlete mode was incorporated as the
distribution of the different body compartments (muscle, bone, fat
etc.) is different in athletes from that in the “normal population“. In
this mode, constants that were obtained by medical studies with
athletes are specified. The different readings are thus due to the
different constants in the software.
How high is the imprecision / tolerance?
The repeat precision when reading ...
- The repeat precision when reading weight measured on a scales is +/- 0.3 kg
- If several scales are compared, the maximum tolerance at a weight of 40kg is +/- 0.5 kg and +/- 1.1 kg at a weight of 100 kg
- The tolerance when measuring body fat or body water is +/- 1%
How often must the electrodes of the LB15 humidifier be changed?
The wear of the electrodes depends on the water used ...
The wear of the electrodes depends on the water used. The more minerals
the water contains, the faster the electrodes wear out. In the case of
water with a “normal“ mineral content, the electrodes have to be
changed after approximately 2 years.
What effect does the ionisation rod of my air cleanser have?
Bacterial production in the water...
Bacterial production in the water is prevented by the continuous
release of silver ions. This chemical process has no negative effect on
the environment and it is nontoxic.
Why do the electrodes of the LB15 humidifier wear out?
The electrodes or more precisely the pair ...
The electrodes or more precisely the pair of electrodes consist of a
positive (anode) and negative (cathode) electrode. At the anode, the
metal is weakened by releasing positive metal ions into the water. As a
result of this release of metal ions into the water, the anode
dissolves more or less slowly.
How often must the filter of the air cleanser be changed?
Experience has shown that the activated charcoal...
Experience has shown that the activated charcoal filter has to be
replaced every 3 months and the HEPA filter every 2 years. These are
recommended guidelines. The working life of the filters is determined
by the degree of use of the device.
How often must the the ionisation rod be changed?
The ionisation rod should ...
The ionisation rod should be changed ever season / every year.
Why do I obtain different values from two consecutive measurements?
This is absolutely normal. The test strips are...
This is absolutely normal. The test strips are produced according to
stringent standardization guidelines. By using a bioenzyme, as with all
biological materials, there could be minute fluctuations which are
within the above standard. As a precaution, the Beurer test strips are
additionally monitored in the lab. This provides for optimum conditions
for reliable measurement.
Why does my doctor measure a different value with his device than I measure with mine, although we measured at the same time?
The doctor will normally take the blood test ...
The doctor will normally take the blood test for blood glucose from the
arm vein. Self-measurement takes place in the fingertip. Different
blood withdrawal site produce different values. Please, read more
detailed information on this question.
What guidelines are there?

Why do I have to encode my device?
To compensate the fluctuations in the production...
To compensate the fluctuations in the production of the test strips,
there are code numbers printed on the test strip container. So that the
device can coordinate with the test strips perfectly, it is important
to enter this code in the device before opening a new container of test
strips. The numerical data on the container of test strips must then
match the number on the device display. The process is very easy and
precisely described in the instructions.
When should I measure my blood glucose?
Type 1 diabetics generally measure before...
Type 1 diabetics generally measure before meals, before going to bed
and additionally with physical strain. They have precise instructions
from their doctor coordinated with their living conditions.
Type 2 diabetics should measure blood glucose on an empty stomach,
because it is the most significant. For this
purpose you shouldn’t have eaten anything two hours before the
measurement. Then your measured value should be less than 120mg/cL. We
recommend monitoring blood glucose two times per week. In the case of
doubt you should follow your doctor‘s instructions.
To receive comparable values, always measure in the same way.
Why should I not use my test strips and control solution after the expiration date?
The test strips and the control solution are ...
The test strips and the control solution are partly composed of
biological substances, which are no longer fully effective after
expiry. On expiry the accuracy of the measured values decreases. In
addition, opened test strips and control solutions are to be used only
within 3 months (after opening).
How / where should I store my blood glucose monitor?
The blood glucose monitor and the accessories are ...
The blood glucose monitor and the accessories are sensitive to
temperature and sensitive to humidity: Please note the following

Do not store the accessories in the fridge. Do not leave your blood
glucose monitor and accessories in the car and do not expose it to
prolonged solar radiation.
What is the operating temperature of my blood glucose monitor?
The operating temperature is from ...
The operating temperature is from +10 to +40°C and a relative humidity from 10 to 85 %.
Is the blood pressure device also suitable for detecting abnormalities of heart rate?
In heart rate disorders, particularly atrial fibrillation...
In heart rate disorders, particularly atrial fibrillation, electronic
devices that use oscillometric measurement are only partially suitable.
In this situation, the blood pressure must be measured with the
stethoscope (Riva-Rocci method) as incorrect results can be obtained
with electronic devices. See notes in the instructions for use.
Do the devices have to be calibrated regularly?
In accordance with the “Operating...
In accordance with the “Operating regulation for medical devices“,
regular technical inspections must be carried out if the device is used
for trade or commercial purposes. Even in the case of private use, we
recommend technical inspection by the manufacturer at 2-year intervals.
Why do I get different readings with my blood pressure device than those at the doctor’s?
Blood pressure readings obtained at the...
Blood pressure readings obtained at the doctor’s practice by the doctor
or practice staff using the standardized Riva-Rocci method of listening
to what are known as the Korotkoff sounds are usually somewhat higher
than the blood pressure readings you obtain when you measure it
yourself in a relaxed atmosphere at home. We call this “doctor’s
surgery“ or “white coat“ hypertension. People who have raised blood
pressure under the stress of everyday conditions can have normal
readings under quiet conditions at the doctor’s. We then speak of
“doctor’s surgery normotension“.
Why are different readings obtained in 2 successive readings?
Blood pressure and pulse depend on many ...
Blood pressure and pulse depend on many factors that can have an effect even in the short term:
- Physical influences
- Medical influences
- Physical exercise
- Muscle tension
- Noise etc
The way the measurement is taken is also relevant:
- cuff applied too tightly / too loosely
- cuff not at heart level
- too short a break between measurements
- no visual or acoustic shielding of the subject
Device tolerances are also important, of course. In the case of devices
with a manometer, there is also parallax error (error in reading the
Why are there differences between measurements on the upper arm and the wrist?
The wrist measurement must be taken ...
The wrist measurement must be taken with the wrist at heart level. If
the arm is laid flat on a table, for instance when you are seated, the
blood pressure is overestimated by approximately 7-8 mmHg because there
is a difference from heart level (1.5cm is equivalent to 1 mmHg).
Incorrect results also occur with wrist measurement in the case of
heart rate abnormalities and changes (e.g. due to age) in the arteries
of the wrist. Particularly in elderly persons, wrist devices may give
imprecise readings. The arteries in the upper arm are not so sensitive
with regard to these influences.
For this reason, occasional measurements on the upper arm are recommended for comparison.
What are the guidelines for systolic and diastolic pressure?
Independent of age, the figures for normal ...
Independent of age, the figures for normal blood pressure according to the German Hypertension League are:
- Upper limits: systolic 140 mmHg / diastolic 90 mmHg
- Ideal reading: systolic 120 mmHg / diastolic 80 mmHg
How long should one wait between 2 measurements?
There should be a break of at least ...
There should be a break of at least 3 minutes before successive measurements.

of the chest belt please change to the menu „Training“. The heart rate
monitor tries to re-connect the devices.
How are the metres in altitude climbed and descended calculated? (PM90)
Metres in altitude climbed or descended are...
Metres in altitude climbed or descended are not assessed until a
difference of +-5 m is reached. Differences in altitude that are smaller
than this are not evaluated, as these may result from weather-related
changes in air pressure. Please note that the graphic in EasyFit may
differ from the data displayed below it. This is because the graphic
displays altitude values every minute but the data below takes into
account the individual altitude in metres that is individually recorded
by the monitor.
How is the number of descents calculated? (PM90)
A descent is only evaluated if the altitude ...
A descent is only evaluated if the altitude difference in metres is more than 50 m without ascents in between (larger than 5 m).
How is the maximum altitude determined? (PM90)
The maximum altitude is determined in...
The maximum altitude is determined in the heart rate monitor itself
using the continuously calculated altitude values. These may differ from
the maximum displayed altitude in the EasyFit diagram, as not all
individual values can be displayed here due to the large volume of data.
