Other possible errors and their solutions
If problems occur when using the device, the following points should be checked:
Malfunction Remedy
• Check battery installation or AC adapter con-
nection is correct and wall outlet is working.
• If the display is unusual, remove the batteries
and then exchange them for new ones.
Check polarity.
• Check the connection of the cuff tube and
connect properly.
1. Ensure the cuff fits properly. (see 5.3)
2. Before starting measurement make sure
that the cuff is not too tight and that clothing
is not exerting pressure on the arm. Take
articles of clothing off if necessary.
3. Measure blood pressure again in complete
peace and quiet.
• Please read the following information and
the points listed under “Common sources of
error”.(5.2) Repeat the measurement.
• Blood pressure changes constantly. The
observed readings may accurately reflect
your pressure.
• Record daily values and consult your doctor.
• Pressure readings in your doctor’s office may
be higher due to anxiety.
• Check cuff connections.
Ensure the unit has not been tampered with.
The display remains blank when the instrument
is switched on although the batteries are in
place.
The pressure does not rise although the pump
is running.
The device frequently fails to measure,
or the values measured are too low or high.
Every measurement results in different values,
although the device functions normally and
normal values are displayed.
Blood pressure values differ from those meas-
ured by my doctor.
After the instrument has inflated the cuff the
pressure falls very slowly, or not at all. (No rea-
sonable measurement possible).
