Before
turning
on
the
power,
first
verify
that
ventilation
holes
on
the
bottom
and
sides
of
the
cabinet
are
free
of
` any obstruction to airflow.
START-UP
On
the
initial
power-up
of
the
instrument,
characteriza-
tions
of
the
vertical
and
horizontal
systems
to
calibrate
portions
of
the
measurement
system
are
done.
After
the
initial
20-minute
warmup
period,
the
seif-characterization
procedure
is
done
automatically
to
adjust
the
gains
and
offsets
to
account
for
the
operating
temperature
of
the
instrument,
and
the
calibration
constants
are
stored
in
memory.
These
start-up
procedures
will
not
be
repeated
again
unless
the
calibration
constants
have
been
lost
from
memory.
A
possible
reason
for
this
to
happen
is
that
the
keep-alive
battery
is
dead
and
in
need
of
replacement.
Refer
the
instrument
to
a
qualified
service
person
if
the
battery
needs
replacement.

is
recommended
that
the
original
carton

for
the
instrument
to
be
reshipped
using
a
commercial
transport
= carrier. If the original materials are unfit or not available,
then
