Section 5-
7B10
CALIBRATION
This section provides information necessary
to:
(1
)
Verify that this
instrument
meets
the
electrical specifications
in
Section
1
,
General Information,
(2)
verify that
all
controls function properly, and
(3)
perform
all
internal adjustments.
The
Part
I--
Performance Check procedure checks
the
electrical
specifications
listed
in
section
1
without
making any
internal
adjustments.
The
Part
II
—
Adjustment and Performance Check procedure
provides a
complete sequential check
of
instrument
performance concurrent with
a
complete sequential adjustment
of
internal controls.
A
separate Operators
Checkout Procedure,
inThe
Installation
section
of this
inanual, can be used
to
check only the functions
of
the front-panel
controls
and
connectors.
PRELIMINARY INFORMATION
USING THESE
PROCEDURES
Both the Part
l-Performance
Check and
Part
11-
Adjustment
and Performance Check
procedures
are
divided into
functional block subsections
(eg.,
A.
TRIGGERING
SYSTEM
and
B.
HORIZONTAL
SYSTEM).
The
order
in
which the subsections and steps (A1, A2,
B1,
B2,
etc.)
appear
in
each procedure
is
the
recommended
sequence
for
accomplishing
a
performance check
or
calibration
of
the instrument.
Subsections within
either
procedure can be performed
independently, as
can each step within any subsection.
Refer
to Partial
Procedures
for
specific instructions
on
performing
either a partial
Performance Check
or a
partial
Adjustment and Performance
Check.
All
functional block
subsections begin with
a
list
of
required
test
equipment, followed by
instructions
for
Before
You
Begin and
the
list
of
Preliminary Control
Settings
for
that
subsection
(e.g.,
TRIGGERING SYSTEM
Preliminary Control Settings,
etc.).
Each
step
contains
separate Setup
Conditions which,
if
applicable, include
the instrument control
settings,
an
illustrated test
setup,
and
test
equipment
control settings.
The
instrument
and
test
equipment
control settings
listed in
the
Setup
Conditions
for
each
step
may
include additional
settings,
changes from
the previous
step, or
changes
to
the
Preliminary Control Settings
making
it
possible
to
perform
partial
procedures.
The Setup
Conditions
illustrate
the setup and
the best
equipment
required to
accomplish
the step
instructions.
Partial
Procedures
Part
I
—
Performance Check.
To perform
a
partial
Performance Check
procedure,
first
determine
which
electrical
specifications are
to
be checked. Table
5-1,
Performance
Check Summary,
lists
the applicable
electrical specifications
and
provides references
to
the
step(s) in
which
the
performance requirements
are
checked.
The Performance Check
Index,
at
the
start of
Part
l-Performance Check,
provides
a
convenient
means
for
locating
the
desired
subsections and
steps.
For
example:
If
the external
trigger amplifier
had been
repaired
and
a
performance check
was
considered
necessary, use the
Performance Check
Summary
table to
locate the specifications affected by the
repair,
and
the
step
title
of Part
l-Performance Check
in
which
those
performance requirements
are checked.
Then
use
the
Performance Check
Index
to
locate the
TRIGGER
SYSTEM
subsection
and
the step
and page number
of
the
applicable
step(s).
Any
step
of a
subsection can be performed separately by
following the instructions given below.
1
Locate the desired subsection
and
applicable steps
(eg
,
B1, B2, B4,
etc
)
with the Performance Check
Summary
table
and
the
Performance Check
Index.
2.
Perform the
Performance Check Power-Up Sequence
at
the
start of
Part
l-Performance Check. Also
follow the
instructions
under Before
You
Begin and
Preliminary
Control Settings
at
the beginning
of
the subsection.
3.
Perform
the
Setup
Conditions instructions
for
the
desired
step.
Disregard
any
control settings
which
are
the
same
as those
under Preliminary Control
Settings.
4.
Proceed with the lettered instructions
(e.g., a, b, c,
etc.).
NOTE
If
the steps
performed
are consecutive,
it
is
not necessary
to
repeat the Preliminary
Control Settings after the
first step.
However,
when
a step
is
skipped, the Preliminary
Control Settings
must be performed
again.
Part
II
—Adjustment and Performance Check.
Although each
step
in
the Part
11-Adjustment
and
Performance Check procedure can
be
performed
independently,
we
recommend
that the entire subsection
be performed
if
any adjustments
are
made.
Table 5-1,
Performance Check
Summary,
lists
the
applicable
electrical
specifications
and
provides references
to
the
step(s) in
which
the
performance requirements are
checked and
appropriate
adjustments
are
made. The
Adjustment and Performance Check
Index,
at
the
start of
Part
11-Adjustment
and Performance
Check, provides
a
convenient
means
for
locating
the desired subsections
and
steps.
For example:
If
the
A1
Interface
board had
been
replaced,
use the
Performance Check
Summary
table to locate
the
specifications affected
by the
repair,
and
the step
title(s)
of
Part
11-Adjustment
and
Performance
Check
in
which
those
performance
requirements
are
checked
or
adjusted.
Then
use the
Adjustment and Performance Check
Index
to
locate the
HORIZONTAL SYSTEM
subsection
and
the step
and page
number
of
the appropriate
step(s).
