Performance Check and Adjustment Procedures
Information in the remainder of this chapter is organized as follows:
Organization of the performance check and adjustment procedures
Procedure index
Procedures
The following describes how the performance check and adjustment procedures
are organized.
Procedure Index.
The “Procedure Index” lists all procedures included in each
subsection. The beginning page number is given for each procedure for easy
location if you intend to perform only a selected procedure or part of a proce-
dure.
Subsection Headings.
The procedures are organized according to major circuit
function. For example: A. Power Supply, B. Display, etc.
Procedure Titles.
The title of each procedure begins with Checking, Adjusting,
Examining, or a combination of these words.
“Checking” indicates that an electrical characteristic is checked.
“Adjusting” indicates that instructions are given to make one or more
internal adjustments.
“Examining” indicates that a functional check of the circuit is performed and
that no electrical specifications are checked.
371B.Setup and Initialization
Each procedure has an “Equipment Setup” illustra-
tion that shows pertinent 371B and test equipment connections and that provides
initialization instructions and control settings.
. You will be instructed to initialize the 371B at the beginning of most
procedures to prevent the carry-over of inappropriate setup conditions from
previous procedures. Initialization also allows you to perform each procedure
independently when only selected parts of the procedure are performed.
When a procedure instructs you to “initialize the 371B,” perform the initializing
instructions under “371B Setup and Initializing” provided earlier in this chapter.
