Calibration Check
The spirometer is calibrated to read in litres at body temperature,
Barometric Pressure Saturated with water vapour (BTPS).
The calibration should remain stable indefinitely, unless the transducer is
physically damaged, and the unit should not require re-calibration. However,
to ensure the correct functioning of the unit we do recommend that a
calibration check is performed after the transducer was removed for
cleaning.
Connect a 3L 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 or a MicroGardfilter 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
reached and then immediately empty the
syringe completely
Press 'Reject' to retry the calibration
check at the required flow rate.
