5.1 Warm Up
Upon turning on the MetaCheck™, it will take a moment to warm up. The warm
up screen is shown following the splash screen. It will automatically end and
begin calibration when the device has warmed up. The enter key will override
the warm up and skip directly to calibration. This may be desired when doing a
large number of tests in succession.

5.2 Automatic Calibration
The MetaCheck™ will calibrate immediately following warm-up. It is completely
self-calibrating. During the calibration, NO HOSE OR MOUTHPIECE SHOULD BE
ATTACHED! If the hose is attached, the MetaCheck™ will beep and display “Please
remove the hose.”
Calibration will typically take 2 to 3 minutes to complete. The third line of the
display will show temperature, barometric pressure, relative humidity, and
oxygen readings during calibration. The fourth line has **** that will scroll across
the screen during calibration.

Figure 5.2 Calibration Screen
During calibration, the MetaCheck™ will draw room air into the system and past
the oxygen sensor. Removing the hose and/or filter from the MetaCheck™ during
calibration assures the free flow of air and thereby accurate calibration. After the
oxygen sensor has been calibrated to room air, the system detects baseline, or
“zero”, flow. During this time it is imperative that no gas flows through the
