Using The Cache - AEMC PEL102 User Manual

4.6 using the cache

Downloaded sessions are saved to the cache, which is located in the "...\My document\DataView\Download\PEL\" folder.
Sessions are cached so they do not need to be downloaded more than once. They are also saved so that if you exit the
PEL Control Panel while downloading, the download can resume (where it left off) the next time the program starts.
■ To open the Cache dialog box select Tools > Cache from the main menu.
■
The Cache dialog box contains a list of instruments on the left side. This list contains instruments from which
sessions where previous downloaded. On the right is a list of sessions that are in the cache for the selected
instrument.
■
Initially the list on the right is empty because no instrument is initially selected. Selecting an instrument on the left will
update the list on the right to display all of the sessions associated with the selected instrument that are currently in
the cache.
■
You can use the cache to open recordings previously downloaded even when the instrument is not connected to
the computer. To do this select the instrument on the left that the session was downloaded from. Next, select the
desired session from the list on the right. Finally, select the Open button to open the session and display it in the My
Open Sessions navigation tree branch.
■
You can remove individually cached sessions from the cache by selecting the desired session and clicking on the
Delete button located under the list on the right.
NOTE: A session cannot be deleted from the Cache dialog box if it is still currently listed in the Download dialog
box. You must first open the Download dialog box (go to Instrument > Download Recorded Data) and hit the
Clear All button.
■
Note that there are two Delete buttons. The one on the left (under the list of instruments) will delete all of the cached
items for the selected instrument. The Delete button on the right (under the list of cached sessions) will delete only
the selected session from the cache.
Each time the PEL Control Panel starts it will calculate how much space is being used on the computer's hard drive and
compare it to the "Maximum allowable cache size" specified at the bottom of the Cache dialog box. If the amount of space
being used by the cache exceeds this amount, a warning message will be displayed. No action will be taken automatically
but will simply inform you if the size of the cache is exceeding the amount specified here.
