Back Up MAS Setting
The AEC Backup Setting screen, shown below, displays the current AEC
backup mAs setting. Note that this is the system-wide backup mAs setting,
and as such, will be effective on all AEC exposures. The procedure-specific
back up time is set using the APR Edit function (refer to APR Edit chapter in
the Operator Manual for instructions on setting individual procedure backup
mAs).
Note: The lower of the two backup settings will take precedence when
set to unequal values.
To change the system-wide backup mAs setting, proceed as follows:
Figure 3-22. Choosing an AEC Backup MAS Setting
1. Adjust the backup mAs setting using the appropriate keys as shown in
Figure 3-22 above until desired backup mAs is displayed. The maximum
back up mAs setting is 600; note that on certain model generators, such
as the Stored Energy models, the maximum mAs capability of the gener-
ator is less than 600 mAs. Therefore, the backup mAs setting should not
exceed the maximum MAS output of the generator. Refer to Chapter 1,
SPECIFICATIONS for a list of the mAs ratings by model number.
2. To save the indicated backup mAs setting and return to the Service Set-
tings Menu, press the key next to the Save field or the Previous Screen
field.
