Section 5—2213 Service
ADJUSTMENT PROCEDURE
INTRODUCTION
IMPORTANT—PLEASE READ BEFORE USING THIS PROCEDURE
PURPOSE
The "Adjustm ent Procedure" is used to return the
instrument to conformance w ith its "Performance Require
ments" as listed in the "S pecification" (Section 1). These
adjustments should be performed only after the checks in
the "Performance Check Procedure" (Section 4) have
indicated a need fo r adjustment o f the instrument.
TEST EQUIPMENT REQUIRED
The test equipment listed in Table 4-1 is a complete
list o f the equipment required to accomplish both the
"Adjustm ent Procedure" in this section and the "Per
formance Check Procedure" in Section 4. Test equipment
specifications described in Table 4-1 are the minimum
necessary to provide accurate results. Therefore, equipment
used must meet or exceed the listed specifications. Detailed
operating instructions fo r test equipment are not given in
this procedure. If more operating inform ation is required,
refer to the appropriate test equipment instruction manual.
When equipment other than that recommended is used,
control settings o f the test setup may need to be altered.
If the exact item o f equipment given as an example in
Table 4-1 is not available, first check the "Purpose" column
to verify use of this item. Then use the "M inim um Spec
ific a tio n " column to determine if any other available test
equipment might suffice.
LIMITS AND TOLERANCES
The limits and tolerances stated in this procedure are
instrument specifications only if they are listed in the
"Performance Requirements" column o f the "Specifi
cation" (Section 1). Tolerances given are applicable only to
the instrument undergoing adjustment and do not include
test equipment error. Adjustment o f the instrument must
be accomplished at an ambient temperature between
+20°C and +30°C, and the instrument must have had a
warm-up period o f at least 20 minutes.
PARTIAL PROCEDURES
This procedure is structured in subsections to permit
adjustment o f individual sections o f the instrument (except
the Power Supply) whenever a complete readjustment is
not required. For example, if only the Vertical section fails
to meet the Performance Requirements (or has had repairs
made o r components replaced), i t can be readjusted w ith
little or no effect on other sections o f the instrument.
However, if the Power Supply section has undergone
repairs or adjustments that change the absolute value o f any
o f the supply voltages, a complete readjustment o f the
instrument may be required.
A t the beginning o f each subsection is a list o f all the
front-panel control settings required to prepare the instru
ment fo r performing Step 1 in that subsection. Each
succeeding step w ithin a subsection should then be per
formed both in the sequence presented and in its entirety
to ensure that control settings w ill be correct fo r ensuing
steps.
ADJUSTMENT INTERACTION
The use o f Table 5-1 is particularly im portant if a partial
procedure is performed or if a circuit requires readjustment
due to a component replacement. To use this table, first
find the adjustment that was made (extreme le ft column).
Then move to the right, across the row, until you come to
a darkened square. From the darkened square, move up
the table to find the affected adjustment at the heading o f
that column. Check the accuracy of this adjustment and, if
necessary, perform readjustment.
