Press 'Again' to repeat the calibration
check (verification) at a low flow rate.
Press 'Again' to repeat the calibration
check (verification) at a high flow rate.
When a calibration check (verification) at
all three flow rates has been completed
press 'Done' to view the calibration check
(verification) report screen.
The calibration error for expiration and
inspiration at each flow rate are displayed.
The calibration error should be less that
3%. If a greater error is shown, repeat
the procedure ensuring that the syringe
is emptied and filled in a smooth manner
without jerking the handle. If an error
greater than 3% is still shown, inspect the
turbine transducer and clean if necessary.
