Order of calibration procedures
The calibration procedures must be performed in the following order:
1 Pressure calibration
2 Flow calibration
3 Motor noise calibration (VPAP III ST-A only)
Cautions
The flow generator clinical settings must be recorded before any calibration procedure is
performed. Refer to the instructions provided in
Section 3 General inspection and
servicing
. If the clinical settings can not be recorded, reset the unit to the factory default
settings via the Flow generator settings window in the service software. The unit can also
be reset to factory default settings via the clinical menu. Once the default settings have
been reloaded, notify the patient.
Warm up the flow generator for at least 15 minutes before commencing the calibration
procedures.
When performing any calibration ensure the humidifier setting in the Settings menu is set
to "none".
