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.

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.
Press 'Reject' to retry the calibration check
at the required flow rate.
