4. Error Messages / Malfunctions

If an error occurs during a measurement, a long beep followed by two short beeps is generated and the LCD
display the corresponding error code.
Error Possible Cause
Err 1 No pulse has been detected.
Err 2 Unnatural pressure impulses influence the
measurement result. Reason: The arm was
moved during the measurement.
Err 3 The inflation of the cuff takes too long. The
cuff is not correctly seated.
Err 5 The difference between systolic pressure
and diastolic pressure is too far away from
acceptable and reasonable range.
Err 6 Due to unstable conditions during measure-
ments, it is not possible to calculate an
average result.
Low battery
Hi
Cuff pressure is over 300 mmHg.
Lo
Pulse below 40 is detected.
If problems occur when using the device the following points should be checked, and if necessary, the
corresponding measures should be taken.
Malfunction
The display remains empty when the device is
switched on. The batteries are inserted.
The pressure does not rise even though the pump is
running.
The device frequently fails to measure the blood
pressure values, or the values measured are too low
or too high.
Remedy
Ensure that the cuff is being worn correctly,
and that you have your arm at the heart level.
Avoid unnecessary movement or talking.
Ensure that the cuff is being worn correctly.
Ensure that the cuff is being worn correctly
and that you have been inactive for a suf-
ficient time before making the measurement.
Avoid unnecessary movement and talking.
Replace batteries.
Ensure that the cuff is worn correctly and
measure again. Avoid movement or talking
when the cuff is being inflated.
Ensure that the cuff is worn correctly.
Remedy
1. Check batteries for correct polarity.
2. If the display is unusual, re-insert the batteries or
exchange them for new ones.
Check the connection of the cuff tube and connect
properly if necessary.
1. Check the positioning of the cuff.
2. Measure the blood pressure again, ensuring that
you have remained motionless for a sufficient
amount of time to ensure an accurate reading.
