System

Preloading enables you  to “preload” at startup, to eliminate the runtime delay.  Preloading an
application will cause it to be loaded into the analyzer’s memory when the analyzer program
starts up. If you do this, the delay will increase the time it takes to start up the analyzer program,
but this may be preferable to having to wait the first time you select an application. Note that,
once an application is loaded into memory, it cannot be unloaded without exiting and restarting
the analyzer program.

Note that there are more applications available for the X-Series than can fit into Windows Virtual
Memory. By allowing you to choose which licensed applications to load at startup, the Configure
Applications utility allows you to make optimal use of your memory.

Access to Configure Applications utility

A version of the utility runs the first time you power up the analyzer after purchasing it from
Agilent. 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.

You may, at any time, manually call up the Configure Applications utility by pressing System,
Power On, Configure Applications, to find a configuration that works best for you, and then
restart the 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. 

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:

1. It will not let you preload more applications than will fit into memory at once.

2. 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.
