The Flow Sensor Positive Calibration should be preformed:
• when the machine is first put into service.
• at prescribed, planned maintenance intervals.
• after the pneumatic vent engine has been serviced.
• whenever the flow sensor is replaced.
Note The Paw Zero, Paw Gain, Flow Zero must be calibrated before the
Flow Sensor Positive Calibration. Select the Calibration
Coefficient menu, set the calibration coefficient as marked on the
calibration orifice before the Flow Sensor Positive Calibration.
1. Remove the bellows assembly, connect the calibration fixture (A)
to the drive gas outlet.
2. Connect the large port of flow sensor (B) to the calibration fixture.
3. Connect the calibration pipe (C) to the small port of flow sensor.
4. Connect the calibration orifice (D) to the calibration pipe.
5. Connect the calibration fitting (E) to the inspiratory flow port.
6. Connect the tubing from calibration pipe to the calibration fitting.
Ensure that the test tubing is leak free.
