Calibration Check (Verification)

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 (verification) 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 receommended that the
transducer is disinfected prior to a
calibration check (verification) or a
MicroGard ® 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
