LOAD STORE/RECALL SETUPS-Loads eight factory front-panel
setups Into the Store/Recall memory. The setups are stored In
memory locations 01 through 08, and all previously stored setups In

message wlll be displayed that will give you the choice to continue or
not continue with the loading of the factory setups. Don't select YES
unless you are sure that you want to delete all of your previously stored
setups.

service technician during calibration and troubleshooting. It Is not an
operational function.
Store/Recall Setup Features
The menu-driven Store/Recall Setup system allows you to store and recall
up to 20 front-panel setups. Front-panel setups are user Installed and
named, and may be arranged In groupings of measurement setup
(sequences) for performing a variety of repetitive tests. Figure 3 4
Illustrates a typical beginning arrangement of tests and sequences with th
factory setups Installed.
There are three different configurations that may be selected to permit dlf
ferent accesses to the STORE/RECALL SETUP features. The first Is th
Recall Only menu for use after the setups have been Installed and no furth r
changes are to be routinely made. '
The Recall Only menu lets you recall the test sequences to perform a serl
of repetitive tests. Only the name and number of the stored record r
displayed along with up and down arrows for selecting higher or low r
numbered setups In a test sequence. If more than one sequence of setup
Is stored, a menu Item (NEXT SEQ) also appears which allows you to
change sequences. See the "Recall Only Menu" discussion.
When configured for full access to the STORE/RECALL SETUP featur ,
stored setups can be recalled, altered, deleted, or arranged In sequenc
This configuration Is used when first Installing the setups and arranging th
sequences. The Store/Recall menu remains displayed after a selection I
made so that It Is convenient to use for making the Initial front panel setup
or making extensive changes to existing setups.

Figure 3-4. Typical Store/Recall Setup sequencing.
The Store/Recall Setup menu with access to Recall Only operates the same
as the Store/Recall Setup menu except that the menu display Is cleared
when the STORE or RECALL Item Is selected. The first choice In the menu
when configured In this manner Is SEQUENCE, and, when selected,
accesses the Recall Only menu for sequencing the setups. This con-
figuration Is useful for making minor changes to existing setups before
beginning a measurement series.
