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