How to Calibrate an Oxygen XCell Sensor

An oxygen span gas cylinder is not needed if the sensor is in an area that maintains ambient air conditions. Follow the same process for XCell sensors as described in How to Calibrate an XIR PLUS Sensor. When the display prompts "Apply Span Gas", simply allow the countdown to occur without applying gas.

If the sensor is located in an area of normally low or enriched oxygen, then a 20.8% oxygen sample must be applied.
