Restarting the tcGas SiteTimer
To restart the site timer without recalibration (for example, after the site time has elapsed):
1 In the Setup tcGas menu, select Site Time.
2 Enter and confirm your desired time.
Disabling the tcGas Site Timer
Depending on your monitor’s configuration, you might be able to disable the site timer. Remember,
this means that the transducer heats indefinitely while on a patient.
1 In Setup tcGas menu, select Site Timer and switch this to Disabled.
2 Select the Confirm popup key.
Setting the tcGas Barometric Pressure
Altitude and barometric pressure affect tcGas values. The monitor derives barometric pressure from its
altitude setting. If you want to set the true barometric pressure you must do this before starting a
calibration - changes after calibration do not influence tcGas values. The monitor remembers this
pressure setting until you enter a new one.
1 In the Setup tcGas menu, select AmbientPress.
2 Enter the current barometric pressure reading indicated by your barometer.
3 Select the Confirm popup key.
Remembraning the tcGas Transducer
CAUTION The tcGas transducer is thin and flexible. You must treat it with care. Avoid kinking, bending or
pulling the cable.
Remembrane the transducer if the electrolyte in your transducer has dried out or:
• if the transducer is new
• if you are using the transducer with a new patient
• if the membranes are damaged (scratched or wrinkled)
• after five days of continued use or 28 days of storage.
