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 it is
recommended that a calibration check (verification) is performed after
the transducer has been removed for cleaning.
Connect a 3L syringe to the transducer
with the minimum of adapters and empty
it by pushing the handle fully in.
Note: It is recommended that the
transducer is disinfected prior to a
calibration check (verification) or a
