6. 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.
Other possible malfunctions and their eliminations
