7. Error messages/troubleshooting
If an error occurs during a measurement, the measure-
ment is discontinued and a corresponding error code is
displayed (example: Error no. 2).
Error No. Possible cause(s)/Solutions
ERR 1
The tube may have loosened, or no pulse was detect-
ed.* Ensure cuff connections are tight with proper cuff
placement. See section 5.3.
ERR 2
Unnatural pressure impulses influenced the measure-
ment result. Reason: The arm was moved during the
measurement (artefact). Repeat measurement,
keeping still and quiet.
ERR 3
Inflation of the cuff takes too long. The cuff is not
correctly seated or the hose connection is not tight.
Re-position cuff and repeat the measurement.
ERR 5
The measured readings 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. Relax for 5 minutes
and repeat the measurement.*
LO
The pulse is too low (less than 40). Repeat the
measurement.*
*If this or any other problem occurs repeatedly, please consult
your doctor.
