9/29/09 RTA (optional) 11-37
Any display which shows a spectrum
can be averaged using the
“+Average” item on its check menu.
Each display that can show a spectrum has a check menu
item, “+Average”, that, when selected, will prompt the user
“Add to Average?”. It then offers the following choices:
• Yes -averages the spectrum being viewed to those previ-
ously averaged.
There is effectively no limit on the
number of spectra that may be
averaged.
• No - the spectrum is not averaged into the previous aver-
age but the spatial average display is shown
• Cancel - nothing happens and the previous display is
shown
Once, one or more spectra have been averaged, they can be
stored into the “Avg History”.
Spatial Avg Check Menu
The Spatial Avg check menu is shown below:
To access the check menu simply press the
c check key
when in the “Spatial Avg” display.
The check menu offers the following options:
• Note- Note is used to describe this average which is to be
stored to the Avg History
The 824 will prompt you to reset the
“Spatial Avg” buffer. This does not
reset the “Avg History”.
• Store - Store Spatial Average in Spatial Average History
• Reset - Resets the Spatial Average buffer
• Avg History - View the Spatial Average History
• Rooms - View Room Criteria for this spectrum
