Asking for an application to be preloaded will cause it to be loaded into the analyzer's memory when the
analyzer program starts up. Once it is loaded into memory, it cannot be unloaded without exiting and
restarting the analyzer program.
Virtual memory usage
There are more applications available for the X-Series than can fit into memory at any one time, so the
Configure Applications utility includes a memory tracker that serves two purposes:
It will not let you preload more applications than will fit into memory at once.
You can determine how many of your favorite applications can reside in memory at one time.
The utility provides a graphical representation of the amount of memory (note that the memory in
question here is Virtual memory and is a limitation imposed by the operating system, not by the amount
of physical memory you have in your analyzer). You select applications to preload by checking the boxes
on the left. Checked applications preload at startup. The colored fuel bar indicates the total memory
required when all the checked applications are loaded (either preloaded or selected during runtime).
Here is what the fuel bar colors mean:
RED: the applications you have selected cannot all fit into the analyzer's memory. You must deselect
applications until the fuel bar turns yellow.
YELLOW: the applications you have selected can all fit into the analyzer's memory, but there is less
than 10% of the memory left, probably not enough to load any other applications, either via preload or by
selecting a Mode while the analyzer is running.
GREEN: The indicator is green when <90% of the memory limit is consumed. This means the
applications you have selected can all fit into the analyzer's memory with room to spare. You will likely
be able to load one or more other applications without running out of memory.
Access to Configure Applications utility
You may, at any time, manually call up the Configure Applications utility by pressing
On, Configure Applications
analyzer program.
The utility may also be called if, during operation of the analyzer, you attempt to load more applications
than can fit in memory at once.
A version of the utility also runs the first time you power up the analyzer after purchasing it from
Agilent. In this case the utility automatically configures preloads so that as many licensed applications as
possible are preloaded while keeping the total estimated virtual memory usage below the limit. This
auto-configuration only takes place at the very first run, and after analyzer software upgrades.
