9.3 Interference Table
Refer to Table 4 Interfering Gases to match the interfering gas symbol with the gas name. Then refer to Table
5 Cross Interference Table which extends for 5 pages, with each sensor specific gas repeated in each section of
the table, for a column listing of 40 gases. The list is followed by a row of 14 possible interfering gases per
page. Review each page for the applicable sensor gas and then scan across the row for possible interference
gases.
