Care And Maintenance, Recalibration - Microlife BP 2BIO Instruction Manual

Malfunction
The pressure does not rise although the
pump is running.
The device frequently fails to measure the blood
pressure values, or the values measured are too
low (too high).
Every measurement results in different values,
although the device functions normally and normal
values are displayed.
The blood pressure values measured differ form
those measured by the doctor.
☞
Further information
The level of blood-pressure is subject to fluctuations even with healthy people. Important thereby is, that
comparable measurements always require the same conditions (Quiet conditions)!
You must consult your specialist dealer or chemist if there are technical problems with the blood-pressure
instrument. Never attempt to repair the instrument yourself!
Any unauthorised opening of the instrument invalidates all guarantee claims!

Care and maintenance, recalibration

a) Do not expose the device to either extreme temperatures, humidity, dust or direct sunlight.
b) The cuff contains a sensitive air-tight bubble. Handle this carefully and avoid all types of straining
through twisting or buckling.
c) Clean the device with a soft, dry cloth. Do not use petrol, thinners or similar solvent. Spots on the cuff
can be removed carefully with a damp cloth and soapsuds. The cuff must not be washed!
d) Handle the tube carefully. Do not pull on it. Likewise, this is not to be buckled or laid over sharp edges.
e) Do not drop the instrument or threat it roughly in any way. Avoid strong vibrations.
f) Never open the device! Otherwise the manufacturer calibration becomes invalid!
Periodical recalibration
Sensitive measuring devices must from time to time be checked for accuracy. We therefore recommend a
periodical inspection of the static pressure display every 2 years.
Your specialist dealer would be pleased to provide more extensive information about this.
Remedy
• Check the connection of the cuff tube and connect
properly if necessary.
1. Fit the cuff correctly on the arm.
2. Before starting the measurement make sure that
the cuff is not fitted too tightly and that there is no
rolled-up sleeve exerting pressure on the arm
above the measuring position.
Take off articles of clothing if necessary.
3. Measure the blood pressure again in complete
peace and quiet.
• Please read the following information and the
points listed under «Common sources of error».
Repeat the measurement.
• Record the daily development of the values and
consult your doctor about them.
