7. Connect the sample tubing from the regulator to the inlet line.
8. Allow the sample-draw detector to draw the calibrating sample for 1 minute.
9. Follow the directions in the controller’s operator’s manual for setting the zero (oxygen free)
reading.
10. Disconnect the gas bag tubing from the sample-draw detector’s inlet fitting.
11. Empty the gas bag.

13. Unscrew the fixed flow regulator from the calibration cylinder.
Returning to Normal Operation
1. Wait 1 to 2 minutes to allow the oxygen reading at the controller to return to normal, then
return the controller to normal operation.
NOTE:
If you do not allow the oxygen reading to return to normal, then unwanted alarms may
occur.
2. Verify that the controller display reading stabilizes at 20.9%.
3. Store the components of the calibration kit in a safe and convenient place.
