If problems occur when using the device, the following points should be checked
and if necessary, the corresponding measures are to be taken:
Possible causes
• The systolic pressure was determined but afterwards the
cuff pressure fell below 20 mmHg.
• The tube may have become unplugged after the systolic
blood pressure was measured.
• No pulse could be detected
• Unnatural pressure impulses impair the measurement
result.
• Possible cause: the arm was moved during the measurement
(artefact).
• Inflation of the cuff takes too long. The cuff is not correctly
placed or the cuff connection is not sealed.
• The measured readings indicated an unacceptable
difference between systolic and diastolic pressures. Take
other reading following directions carefully.
• Single data differ too much during an Average Mode
reading even after 4 cycles. No average result can be
displayed.
• When «ERR 7» appears, the device is put automatically in
«TEST» mode
