Things to Know Before Taking Measurement
To assure accurate measurement, please observe the following:
Make sure that electrodes are directly in contact with your skin.
If your skin or hands are dry, moisten your skin with damp cloth before taking measurement.
If the electrodes are dirty, use a soft cloth or a cotton swab moistened with disinfectant alcohol to
clean dirt from the surface.
During the measurement, do not touch your body with the hand with which you are taking the
measurement.
Make sure there is no skin contact between your right and left hand (measuring method C), or
between your hand and chest (measuring methods A/B). Otherwise, the measurement cannot be
taken correctly.
Ideally perform the measurement either sitting down or lying down. Do not stand up.
Do not move or talk during the measurement and hold the device still. Movements of any kind will
falsify the measurements.
6. TAKING MEASUREMENT
Operation Procedure
There are three different methods of taking the measurement. Start with measurement method A, “right
index nger-chest.” If this method does not deliver measurements, or delivers only unstable
measurements (“EE” is frequently displayed), switch to method B “left index
chest” and, if
necessary, to method C”left hand-right hand.”
The most suitable method/ procedure depends on the heart (shape of the heart) of each
individual user. If it is not possible to take stable measurements using a given measurement method, this
could have a harmless cause such as the shape of the heart. However, the cause may also be an illness or
disease.
Measurement method C offers maximum comfort, but offers a much lower measurement stability than
methods A or B.
Press the on/ off button for about three seconds to turn the device on. The device shows the full display.
WARNING
If segments are missing, stop using the device and immediately contact customer services. To test whether
the full display is completely displayed, hold the On/Off button when switching on the device.
Measurement Methods

Top Electrodes
Place y wo upper electrodes on the device
and hold the device
You can determine the correct position for placing the lower electrode of
the device against your chest using the following methods:
• Draw an imaginary line from the front of your armpit downwards. At the
same time, draw an imaginary line going up 10 cm from the lowest rib on
the left side of your body. Place the lower electrode of the device at the
point where these two lines meet.
5 cm
• Draw an imaginary line from the bottom of the centre of your chest
(sternum) to the left. At the same time, draw an imaginary line from the front
of your armpit downwards. Place the lower electrode of the device at the
point where these two lines meet.
