X−Ray Generation

As Illustration 6−2 demonstrates, the majority of the battery pack’s capacity is used
for drive and idle. Thus, reducing the amount of drive time by parking the AMX−4+
in a central location and turning the system OFF when not in use will make more ca-
pacity available for x−ray generation and will increase the service life of the batteries.

Note:

See the Ratings and Specification Section, 9−7 for more detail on how
total AMX−4+ battery capacity is determined.

Bar Graph Display vs Battery Loading

Table 6−1 details the various battery loads and how they affect the bar graph display.
