*A
MODE
The
*A
Mode is used
to
1)
determine
the
numberof
locations allocated
to
Input, Intermediate, Final
Storage Area2, and
FinalStorage
Areal;2)
repartition
this
memory; 3) check
the
number
of
bytes remaining in Program memory;
4)erase
Final
Storage; and
5)
to
completely
reset
the datalogger
(just
as
if power were
turned
otf and
then
on again).
A
second
Final Storage
area
(Storage Area
2)
can be allocated
in
the
*A
Mode.
On power
up,
locations allocated
for Storage
Area
2 defaults
to
0.
Final Storage
Area
1 is
the
source from which
memory
is
taken
when
Input, Intermediate, and
Final Storage Area
2
memories
are
increased.
When
they are
reduced, Final Storage
Area
1
memory is
increased.
Allocation
of
lnput and
Intermediate
Storage
locations
does
NOT change
Final Storage Area
2
and therefore, the
data
in
this
area
are preserved.
When "A
is
entered, the
first
number
displayed
is
the
number
of
memory locations allocated
to
Input
Storage. The "A"
key is used to advance through
the
next
4
windows.
Table
1.5-2 describes
what
the
values
in
the
*A
Mode represent.
The
number
of
memory locations allocated
to
Input,
lntermediate
and
Final
Storage Area2
defaults
at
power-up to the
values
in
Table
1.5-1.
The
size
of
Finalstorage
is
determined by the size of RAM.
The
sizes
of
Input, lntermediate
and
Final Storage
Area2
may be altered by keying
in
the desired
value and entering it by keying
"A".
One
Input
or
Intermediate Storage location
can
be exchanged
for
two
Final Storage
locations. The
size of Final
Storage
Area
1
will
be adjusted automatically.
