6. Error messages/malfunctions
Error No.
Possible cause(s)
«Err 1»
The systolic pressure was determined but after- wards 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.3 sec.
«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 reading indicated an unacceptable difference between systolic and
diastolic pressures
Take another reading following directions carefully. Contact your doctor if you
continue to get unusual readings.
HI
The cuff pressure is too high. *
The measured pulse is higher than 200 beats/min.
LO
The measured pulse is lower than 40 beats/min. Repeat the measurement.*
*If this or any other problem occurs repeatedly, please consult your doctor.
Other possible malfunctions and their elimination
If problems occur when using the device, the following points should be checked and if necessary,
the corresponding measures are to be taken:
Malfunction
Remedy
The display remains empty when the instru-
ment is switched on although the batteries
are in place.
1. Check batteries for correct polarity and if neces-
sary insert correctly.
2. If the display is unusual, re-insert batteries or
exchange them.
The device frequently fails to measure the
blood pressure values, or the values meas-
ured are too low (too high).
1. Check the positioning of the cuff.
2. Measure the blood-pressure again in peace and
quiet under observance of the details made under
point 5.
If an error occurs during a measurement, the measurement is discontinued and a co-
rresponding error code is displayed, the device automatically reminds you “measuring
failed, please try it again”. (Example Error no. 1)
