If an error occurs during a measurement, the measurement 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 detected.* Ensure cuff
connections are tight with proper cuff placement. See section 5.3.
ERR 2 Unnatural pressure impulses influenced the measurement 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.
