9.2 Interference Table
Reference Table 5 to match the interfering gas symbol with the gas name. Then refer to Table 6. The Cross
Interfering Gas Table extends for 5 pages, with each sensor specific gas repeated in each section of the table,
for a column listing of 40 gasses. The list is followed by a row of 14 possible interfering gasses per page.
Review each page for the applicable sensor gas and then scan across the row for possible interference gasses.
