5.3.1 Creation of New Programs
In addition to the Two (2) factory preinstalled
programs, the user may create custom programs.
Each program is comprised of 4 segments just as
the preprogrammed procedures are structured.
Each temperature segment is defined by its initial
temperature and its final temperature.
The user must then also define the time duration
of each segment as well as the type of gas and its
flow rate.
