To identify any component
Locate the Circuit Board Illustration
mounted on a circuit board and
to locate that component in the In the instrum ent identify the Assembly Number of the
appropriate schematic diagram 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
nom enclature are printed on the back side of the tabs
(facing the rear of the manual)

Locate th e C om p o n en t on th e C irc u it Board
In the manual, locate and pull out the tabbed page whose
title and Assem bly Number correspond w ith the desired
circuit board. This inform ation is on th e back side of the
tabs.
Using the C ircuit Number and grid coordinates, locate the
com ponent on the C ircuit Board Illustration.
In the circu it board location illustration, determ ine the
location of the circuit board in th e instrum ent.
Find the circuit board in the instrum ent and compare it
w ith its illu s tra tio n in th e m anual to locate the desired
com ponent on the board.

2. Determine the C ircuit Number
.. Compare the circuit board w ith its illustration and locate
the desired component by area and shape on the illustra­
tion.
b Scan the taNe adjacent tothe Circuit Board Illustration and
find the Circuit Number of the desired component.
c. Determine the Schematic Diagram Number in which the
component is located.
