If the following measurement shows a lack of stability again,
repeat the measurement after another period of rest. In case of
further unstable measurements, identify these measurements
as they were taken when the circulatory system had not be suf-
ficiently rested.
In this case, inner unrest of the nervous system could be the
cause, which cannot be cured by brief periods of rest. Devel-
oping cardiac arrhythmia can also prevent stable blood pres-
sure measurements.
A lack of resting blood pressure can have various causes, such
as physical or mental strain or distraction and speaking or
experiencing heart rhythmic disturbance during the measure-
ment.
In an overwhelming number of cases, the HSD diagnosis will
give a very good guide as to whether the circulatory system is
rested when taking the measurement. Certain patients suffer-
ing from cardiac arrhythmia or chronic mental conditions can
remain haemodynamically unstable in the long-term, some-
thing which persists even after repeated periods of rest. The
precision of the results of the resting blood pressure is reduced
in these users. Like any medical measurement method, the
precision of the HSD diagnosis is limited and can lead to incor-
rect results in some cases. The blood pressure measurements
taken when the circulatory system was at rest represent par-
ticularly reliable results.
6. Saving, retrieving and deleting results
The computer automatically saves the blood pressure readings
of the last 60 measurements. When the 60 memory locations
are exceeded, the current oldest value is deleted.
You can display the memory as follows:
• Press the user selection button
to select a memory zone,
and press the M key to switch from memory to memory with
sequence numbers.
• The average value of the last three measurements is
displayed first.
• Continue pressing the memory button to recall other indi-
vidual measurement results - the first result to appear is that
of the most recent value measured.
• Press the On/Off switch to turn the unit off.
• If you forget to switch off the computer, it will switch off auto-
matically after 1 minute.
Press the user selection button to select a memory zone,
then press and hold the M key for approximately 5-seconds to
clear the data in the pre-designated memory zone.
7. Cleaning and storing the instrument
• Clean your device and cuff carefully only with a slightly mois-
tened cloth.
• Do not use detergents or solvents.
• On no account must you immerse the computer in water,
otherwise liquid can enter it and cause demage.
• When storing the device, make sure that no heavy objects
are placed on top of it. Remove the batteries. The cuff tube
should not have any sharp kinks.
8. Rectifying faults
Error messages can occur when
• measurement error ( appears in the display),
• you move or talk during the measurement ( appears in the
display),
