Rosemount Analytical µCEM Continuous Analyzer Transmitter 4-18
4.3.6 µCEM Settings-Maintenance Mode
Maintenance mode may be selected for any of the emission types on the Maintenance
Mode page of the µCEM Settings.
Choosing maintenance mode will invoke an “M” flag” onto the data. Customer can
perform routine maintenance while in this setting
This mode is typically used when preventive maintenance is being performed. The M
flag signifies to the EPA that the values reported are not valid therefore should not be
applied to emissions reporting.
Upon completion of Maintenance the user must go back into this screen to turn the
Maintenance off. If not, the MicroCEM will continue to show the M flag in the data.
