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 receommended that the
transducer is disinfected prior to a
calibration check or a MicroGardfilter is
used during the procedure.
