Sensor Calibration
The Capnostat® CO
2
sensor does NOT need to be calibrated at each monitor power up.
Calibration of a sensor is required the first time a particular sensor is connected to a
particular monitor and when the monitor requests it.
Once a sensor is calibrated, the Passport XG can be turned off and on, the sensor can be
unplugged and reconnected, without having to recalibrate. However, if a second sensor is
connected in place of the original, the second sensor must be calibrated and if the original
sensor is used again, it too will have to be recalibrated.
NOTE: In order to perform an accurate Sensor calibration, the
“Sensor Warming Up” message must not be displayed.
To perform a Capnostat® sensor calibration:
1. Verify the Passport XG is turned on and the Capnostat® is plugged in and warmed-up.
