Meaning
• Before a drift is computed for this sensor, its auto- null valve is opened to atmosphere. A test is performed to ensure that the valve has fully opened in accordance with the time provided by the technical specification. This is performed by ensuring that the control pressure has dropped significantly enough after the valve has opened and a de-bounce time has expired. If the pressure reading before the valve was opened was not high enough (due to ventilator therapy settings) to provide a valid criteria regarding a significant drop in pressure, then the check is not performed. When this condition is in effect for a consecutive number of attempted drifts, the error is reported
