6. Error Messages/Troubleshooting
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)
ER 1 The systolic pressure was determined but after-
wards 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.
ER 2 Unnatural pressure impulses influence the
measurement result. Reason: The arm was moved
during the measurement (Artefact).
ER 3 Inflation of the cuff takes too long. The cuff is
not correctly seated or the hose connection is not
sealed.
ER 5 The difference between systolic and diastolic is
excesive. Measure again carefully following proper
cuff procedures and ensure measurement under
quiet conditions. Contact your doctor if this
message occurs frequently.
