MetaCheck™. If gas flow is detected, the system will indicate that error number
112 (Device cannot be Zeroed) has occurred. If this error is detected, calibration
time will be prolonged. However, no user interaction, other than to prevent any
flow through the system, is needed to correct this problem.
When calibration is complete, the text on the display will read “Calibration
complete, waiting for first breath.” The MetaCheck™ will “chirp” periodically to
indicate this.

5.3 Connect the MetaBreather™ to the MetaCheck™.
The MetaBreather™ is expandable to a length of approximately 5 feet (1.5
meters). Extend the hose to its full length prior to connecting the hose to the air
intake on the MetaCheck™ instrument. Place the filter between the hose and air
intake.
5.3.1 Comfort
Verify with the patient that the mouthpiece will be comfortable. Flex the
tube to a position that will support itself. The mouthpiece can be rotated
within the tube to ensure comfort.
5.3.2 Safety
The MetaCheck™ will analyze all of the air exhaled during the test. To
ensure that only exhaled air passes through the system, one-way valves
are built into the MetaBreather™ mouthpiece. During inspiration, the
intake valve is open allowing room air to enter the mouthpiece and the exit
valve is closed ensuring that no room air enters the MetaCheck™.
During exhalation, the intake valve is closed to prevent leakage to the
room and the exit valve is open ensuring that all expired gas passes freely
through the MetaCheck™.
Warning: Do not connect the Metabreather before calibration is
complete and the text on the display indicates that the system
is waiting for the first breath.
