The TOC Maintenance menu allows recording the completion of standard maintenance tasks that are
not controlled through menu operation, as well as access to certain features that may be needed
during system maintenance. These features include UV Lamp or Inlet Filter Replacement, display or
manual control of TOC Sensor sample flow rate, or resetting the Lamp Power Cycles Today counter.
Operations such as calibration and system suitability testing are automatically recorded at the
completion of these tasks.
