PROGRAMMING CYCLE VALUES
The Amsco Century Medium Steam Sterilizer is factory programmed with
default processing cycles and cycle values (see Table 8-1). These preset
values (parameters) can be modified to process varying loads which occur in
the sterilizer's operating environment.
NOTE: Control will default to the factory-programmed values if a battery or
battery-powered memory failure occurs.
This section outlines how to change the cycle values only. For details on
modifying the sterilizer operating parameters, refer to
