To identify any component
mounted on a circuit board and
to locate that component in the
appropriate schematic diagram
Locate the Circuit Board Illustration
In the instrument identify the Assembly Number of the
circuit board in question. The Assembly Number is usually
printed on the upper left corner of the circuit board on the
component side
In the manual locate and pull out tabbed page whose title
corresponds w ith the Assembly Number of the circuit
board Circuit board assembly numbers and board
nomenclature are printed on the back side of the tabs
(facing the rear of the manual)

2. Determine the Circuit Number
..
Compare the circuit board w ith its illustration and locate
the desired component by area and shape on the illustra
tion.
Scan the taNe adjacent tothe Circuit Board Illustration and
find the Circuit Number of the desired component.

c.
Determine the Schematic Diagram Number in w hich the
component is located.

3. Locate the C ompo nent on the Schem atic Diagram
a. Locate and pull out tabbed page whose number and title
correspond with th e Schematic Diagram Number just
determined in the table. Schematic diagram nomenclature
and numbers are printed on the front side of the tabs
(facing the front of the manual).
Scan the Component Location Table adjacent to the
schem atic diagram and fin d the Grcuit Number of the
desired component
Under the SCHEM LOCATION column, read the grid
coordinates for the desired component.
Using the Circuit Number and grid coordinates, locate the
component on the schematic diagram.

Locate the Com p o nent on the Circuit Board
In th e manual, locate and pull out the tabbed page whose
title and Assembly Number correspond w ith the desired
circuit board. This in form ation is on th e back side of the
tabs.
Using th e Circuit Number and grid coordinates, locate the
component on the Circuit Board Illustration.
In th e circuit board location illu stration, dete rmine the
location of the circu it board in the in strument.
Find the circuit board in the instrum ent and com pare it
w ith its illu stration in the manual to locate the desired
com ponent on the board.
4. D ete rmine the C ircu it Board Illustration and Component
Location
a. From the schematic diagram, determine the Assembly
Number of the circuit board on which the component is
mounted This information is boxed and located in a corner
of the heavy line that distinguishes the board outline.
Scan the Component Location Table for the Assembly
Number just determined andfm d theG rcu it Number of the
desired component.
Under the BOARD LOCATION column, read the grid
coordinates for the desired component
