Error messages/malfunctions
If an error occurs during a measurement, the measurement
is discontinued and a corresponding error code is displayed.
(Example Error no. 1)
Error No. Possible cause(s)
ERR 1
The systolic pressure was determined but afterwards the cuff pressure fell below 20 mmHg.
This situation can occur, for example, if the tube becomes unplugged after the systolic blood
pressure has been measured. Further possible cause: No pulse has been detected.
ERR 2
Unnatural pressure impulses influence the measurement result. Reason: The arm was moved
during the measurement (Artefact).
ERR 3
Inflation of the cuff takes too long. The cuff is not correctly seated or the hose connection is
not sealed.
ERR 5
The measured readings indicated an unacceptable difference between systolic and diastolic
pressures. Take another reading following directions carefully. Contact you doctor if you
continue to get unusual readings.
HI
The pressure in the cuff is too high (over 300 mmHg) OR the pulse is too high (over 200 beats
per minute). Relax for 5 minutes and repeat the measurement.*
LO
The pulse is too low (less than 40 beats per minute). Repeat the measurement.*
* Please consult your doctor, if this or any other problem occurs repeatedly.
Malfunction
The display remains empty 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 the
blood pressure values, or the values
measured are too low (too high).
Every measurement produces a different
value although the instrument functions
normally and the values displayed are nomal.

Remedy
1. Check whether the batteries are installed with the
correct polarity and correct if necessary.
2. If the display is unusual, remove the batteries and then
exchange them for new.
• 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.
