Making a temperature-programmed run

Making a temperature-programmed run
You can program the oven temperature from an initial temperature to a final
temperature using up to six ramps during a run.
A single ramp temperature program raises the initial oven temperature to a
specified final temperature at a specified rate and holds at the final temperature
for a specified period of time.

The multiple-ramp temperature program is similar. You can program the oven
from an initial temperature to a final temperature, but with various rates, times,
and temperatures in between. Multiple ramps can also be programmed for
temperature decreases as well as increases.
