2.6. Flow Adapter Cap

The Analyzer includes a Flow Adapter Cap with flexible tubing and flow orifice. It attaches to
the Sensor port and is sealed by an o-ring. It can be used to direct the gas sample flow to
the Sensor via one of two methods:
Direct Flow Method Sample Flow Method
Flow is Directed to Flow is Delivered from
Flow Orifice on Face Low Pressure Source
of Flow Adapter Cap via Flexible Tubing
Vent Hole
Flow to the sensor needs to be restricted to .5-1liter of pressure maximum. Nuvair offers flow
restrictors to accomplish this task. See appendix.

3.0 Calibration

Oxygen Analyzers must be calibrated before each use. Improper calibration may
result in the use of incorrect breathing gas mixtures, which may cause serious injury
or death to the person using the gas mixture.
Calibration or use of the Analyzer with a low battery may result in inaccurate readings.
Inaccurate gas analysis can lead to serious personal injury or death.
When Analyzer calibration is performed at different atmospheric conditions than the
gas being measured, a calibration correction value may be required. Improper
calibration may result in the use of incorrect breathing gas mixtures, which may cause
serious injury or death to the person using the gas mixture.
If the Analyzer has been subjected to a recent change in ambient temperature, allow it
to stabilize for one hour before checking calibration.
During the warm up time if the oxygen percentage of the mixed gas flow is different
from the value of calibration set in the instrument, a failed calibration is obtained and a
wrong analysis value will be displayed.
