NOTE . Check the Change Information section in the rear of the manual for
corrections and modifications to the instrument and the manual.
Look Up Charts. Each schematic diagram is assigned an alpha-numeric grid and a
look-up chart which lists the grid location of components on that schematic and
on the circuit board.
Circuit Board Illustrations.
Electrical components, connectors, and test points are
identified on circuit board illustrations, which are located on the back of the
schematic diagrams. Circuit board illustrations are assigned an alpha-numeric
grid which corresponds to the lookup charts accompanying the schematics.
Assembly and Circuit Numbering.
All circuit board assemblies are assigned
assembly or “A” numbers. Figure 7–2 shows the assembly numbers and their
locations for this instrument.
NOTE . Always check the parts list for part numbers and descriptions when
ordering replacement parts. Some parts may have been replaced or have a
different value in an individual instrument.
