The
following
procedures
should be performed to
es-
sure the user
that the instrument
has
arrived
at its
4.
destination
in satisfactory
operating
condition. Com-
plete calibration
and checkout
instructions are pro-
5.
vided in Section
4 to determine
compliance with elec-
6.
trical specifications.
Checking
Visually
/.
After carefully unpacking the
instrument, visually
in-
spect the
external parts for damage to
knobs,
dials,
indicators,
surface areas,
etc.
If damage
is
discovered,
file
a
claim with
the
carrier who transported the in-
strument. Retain
the
shipping
container
and
packing
material for
use in
case reshipment
is
required.

The
steps in this paragraph provide a quick checkout
of
the instrument operation. If
