in Chapter 4 for an overview of the Save/Recall
functions.
This section provides details on the size of Save/Recall instrument state
files.
Since disks have limited storage capacities, it is often important to know how
many instrument state Eles will Et on a disk, and how to reduce the size of
each Ele in order to maximize storage.

The analyzer is capable of saving complete instrument states for later
retrieval. It can store these instrument states to any one of the following:

The non-volatile RAM disk is powered by a battery, to provide short term
storage of data when the analyzer is not connected to ac power. With
this battery protection, data can typically be retained in memory for
approximately 250 days at 70
O
C and for more than 5 years at 25
O
C.
The number of Eles that can be saved to disk is limited by the space available
on the disk.
The number of bytes available for storage are displayed in the upper
right-hand portion of the disk catalog window, after the words “Bytes Free.”
