* The performance specifications for stack gas moisture based on wet O2 measurements (calibration drift, response time, relative accuracy, and availability) are summarized in Table 3 and Table 5. Other moisture monitoring systems may be used to correct dry measured concentrations, if it is demonstrated that the system is able to calculate the hourly factor (100 - Bws) with an error ≤2.0% all year round. The specific QA activities related to the moisture monitoring system must then be described in the QA/QC manual. Further details on the use of stack gas moisture monitoring systems are presented in Section 7. Note that Bws is the moisture content of the stack gas (in % of volume)
