Operating Overview
Saving and Recalling Instrument Setups
BASE Settings
The BASE register contains any field settings the user has saved that
are different from the instrument preset state. It establishes a
reference point for all future saves. If a base is not saved, the preset
state is used as the reference.

state is used as the reference.
When you save an instrument setup, the new setup is compared to the
base settings, and any differences are stored under the register name
you supply. Because only differences are stored, a much larger number
of instrument setups can be saved than if the contents of every field was
saved.

When you recall an instrument setting, every field is reset to the base
settings. The saved settings are then used to re-establish the desired
instrument setup.

You can define your own base setting. If your desired settings are very
different from the preset values, you may want to change the BASE
register. This will decrease the amount of memory used to save each
setup, and allow you to save many more setups.

CAUTION
Since each save/recall register only contains the
differences between the setup being saved and the present
base register settings, changing the base settings causes
all other saved setups to be erased from memory
(including the POWERON setting if one has been saved).
Unless you consistently change the same fields to the
same value each time you use the instrument, you should
avoid creating your own BASE settings.

Memory Considerations
When the
Save/Recall
field of the I/O CONFIGURE screen is set to
Internal
, programs are saved to the same non-volatile RAM used to
create RAM disk(s) and run IBASIC programs. By saving a large
number of instrument setups, you reduce the amount of RAM available
to run programs. If you get a “memory overflow” message while trying
to load a program, you must clear one or more save/recall registers to
free RAM space.

Instrument Hardware Changes
Recalling a saved register that uses a hardware option that has been
removed results in unspecified operation. Re-install the needed option
before attempting to recall the associated register(s).
