WARNING:
Before
turning
on
the
instrument,
ensure
that it has been
installed
In accord-
ance with the Installation
Instructions
outlined in
Chapter
1 of the
Operators Ma-
nual.
This performance procedure is intended to:
—
Check the
instrument’s
specification.
—
Be used for
incoming
inspection to determine the
accept-
ability of newly purchased
instruments
and
recently reca-
librated instruments.
—
Check the necessity of re calibration after the
specified
recalibration intervals.
NOTE: The procedure does not check
every
facet of the in-
strument’s calibration; rather, it is
concerned
primarily
with those parts of the instrument which
are essential
for determining the function of the instrument
it is
not necessary to remove the cover of the
instrument
to
perform
this procedure.
If
the test is started less than 20 minutes after
turning
on
the instrument, results may be out of
specification,
due to
insufficient warm-up time.
