Accuracy of controls
English 145
Notes:
•
All flows and volumes are measured at BTPS conditions.
•
To achieve specified accuracies, a successful Learn Circuit must be performed prior to measurement testing.
Specified accuracies exclude mask compliance.
•
Pressure may be displayed in cmH
2
O, hPa or mbar. The conversion factor of the pressure units is 1. This means
the displayed pressure will have the same values regardless of the unit selected.
