conjunction with, or in place of, special diagnostic programs or test equipment
and shall be presented in a simple logical order which is suited to actual oper-
ation of the system itself.
3.4.5.4.2.1.1
System Level Diagrams. - The system level of trouble-
shooting (see figure 2) shall be a presentation of symptom collection and diag-
nosis with the system energized system displays, such as printers, plotters,
CRT display tubes, etc, as the source of symptom information. The system
level diagram shall delineate information that would lead to localization of a
