Oxygen Sensor Calibration
Screen 11: Oxygen Sensor Calibration
The Oxygen sensor calibration screen can be accessed from the main menu for periodic
calibration. The calibration procedure uses the Nitrogen supply to determine the low (0%
Oxygen) operation point and the ambient atmosphere for the high operation point. The
Atmospheric Oxygen level is set to 20.9% as default but this can be changed if required.
Once this setting is entered to the correct level, pressing the start button will begin the
automatic calibration procedure and the time remaining will start decaying to zero. Once
the calibration procedure is complete the Oxygen sensor will then re-settle to the current
workstation environment level.
