Page 6 of 23 11/14/200 6 Rev. 14 Oxygen Exponent The range of ox y gen is factor y configured using the oxygen exponent number. Percent oxygen is the standard setting where the oxygen exponent is set to 2 and the output range is 0.00% to 20.9%. For a part per million ( ppm) range the exponent would be set to 6 and the output range of 0.
