Calibration Check (Verification) - Vyaire MicroLab Manual De Funcionamiento

Calibration Check (Verification)

The spirometer is calibrated to read in liters at body temperature,
Barometric Pressure Saturated with water vapor (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
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 constant rate until the end stop is
reached and then immediately empty the
syringe completely.
Press 'Reject' to retry the calibration
check (verification) at the required flow
rate.
