7. Error Messages/Troubleshooting
If an error occurs during a measurement, the measurement is dis-
continued and a corresponding error code is displayed. We recom-
mend you switch the device off and take a new measurement making
sure you allow time for relaxation (Example: err 3).
Repeat measurement keeping arm
still.
If inflation of the cuff takes too long,
the cuff is not correctly seated or the
tube connection’s not tight.
Check connections and repeat.
The difference between systolic and
diastolic is excessive. Measure again
carefully following proper cuff proce-
dures and ensure measurement under
quiet conditions.
