muscle tension. Repeat the
measurement, keeping your
arm still.
Err 3 Abnormal cuff pressure An adequate pressure cannot
be generated in the cuff. A
leak may have occurred.
Check that the cuff is
correctly connected and is
not too loose. Replace the
batteries, if necessary.
Repeat the measurement.
Err 5 Abnormal result The measuring signals are
inaccurate, and no result can
therefore be displayed. Read
through the checklist for
performing reliable
measurements. Repeat the
measurement.
HI Pulse or cuff pressure too
high
The pressure in the cuff is too
high (over 299 mmHg) or the
pulse is too high (over 200
beats per minute). Relax for
5 minutes and repeat the
measurement.
LO Pulse too low The pulse is too low (less
than 40 beats per minute).
Relax for 5 minutes and
repeat the measurement.
Other possible errors and their solutions
Malfunction
Remedy
The display remains blank when the device is
switched on though the batteries are in place.
1. Check battery installation/ polarity.
2. Remove the batteries and if the display is unusual, then
exchange them for new ones.
The pressure does not rise although the pump is
running.
Check the connection of the cuff tube and connect properly.
The device frequently fails to measure, or the values
measured are too low or high.
1. Fit the cuff correctly on the arm.
2. Before starting measurement make sure that clothing is
not exerting pressure on the arm. Take articles of clothing
off if necessary. Measure blood pressure again in complete
peace and quiet.
Every measurement results in different values,
although the device functions normally and normal
values are displayed.
Refer to Sectionx About Blood Pressure
Blood pressure values differ from those measured at
the doctor’s.
Refer to Section x Why Measure Blood Pressure at
Home?
NOTE: Blood pressure is subject to fluctuations even in healthy people. Please remember that
comparable blood pressure measurements always require the same time and the same
conditions! These are normally quiet conditions. If you follow the procedure described earlier
and still get fluctuations of blood pressure of greater than 15 mmHg and/or you repeatedly hear
irregular pulse tones, consult your doctor.
