from the
rear
panel,
the
instrument
may
properly
store
its state
in
position
1 but
this
is
not
guaranteed.
(This
is related to

time.
The
sequence
of events
is
predictable
when
using
the
front
panel
POWER
push
button
but
not with
a
simple
removal of
mains.)
As
stated
earlier,
the
instrument
always
powers
up
in its
default state
(Memory
0).
Alternatively,
the
instrument
can
be
modified
to
power
up
in the same
state it was in
during
a
valid
power-down
sequence.

To
change
the
instrument to
power
up
in
the
last
power
down
state,
key
in
23.1
SPCL.
The next time the
instrument
is
powered
up,
it will
start in the last
power-down
state. To
return to the normal
default
power-up
state,
key
in
23.0 SPCL.
If the
last state at
power-down
was
not suc-
cessfully
stored for
any reason,
at next
power
up,
the default status
will be
recalled rather
than an erroneous
and
possibly
illegal
state.
The
instrument
always
checks the
validity
of
data
prior
to a recall to
avoid
placing
the
instrument
in an invalid
state.
