Connect a 3-liter syringe to the
transducer with the minimum of
adapters and empty by pushing the
handle fully in.
Note: It is recommended that the
transducer is disinfected prior to a
calibration check (verification) or a
SpiroSafe filter is used during the
procedure.
Select ‘Calibration Check’ from the
main menu and then select ‘Check
Calibration’.
Fill the syringe by pulling the
handle at a constant rate until the
end stop is reached and then
immediately empty the syringe
completely. Try to maintain a flow
rate that keeps the trace within the
grey bands on the display.
Select ‘Reject’ to retry the
calibration check (verification) at
the required flow rate.
Select ‘Again’ to repeat the
calibration check (verification) at a
low flow rate.
Select ‘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 select ‘Done’
to view the calibration check
(verification) report screen.
