Error Messages/Malfunctions - Microlife BP 3BTO-1 Instruction Manual

7. 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 The inflation of the cuff takes too long. The cuff is not correctly seated.
ERR 5 The measured results have indicated an unacceptable difference between the systolic and
diastolic pressure. Take another measurement, carefully following the instructions. Contact
your doctor, if you still obtain unusual results.
ERR 6 Single data differ too much during Average Mode even after 4 cycles. No average result can
be displayed.
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 possible solutions – If problems occur when using the device, the
following points should be checked and if necessary, the corresponding measures are to be taken:
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).
Remedy
1. Check whether the batteries are installed with the
correct polarity and correct if necessary.
2. If the display is unusual, re-insert batteries or
exchange them.
• 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.
