You can program the oven temperature from an initial
temperature to a final temperature using up to 5 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.
Final temperature 1
Rate 1
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.
Final temperature 2
Rate 2
Final time 1
Rate 1
Temperature Starting temperature of a temperature
programmed run. When the program begins, this value is copied
into a temporary setpoint called Init temp. At the end of the run,
Temperature is reset to the value in Init temp and the oven returns
to its starting temperature.
Initial time Time in minutes that the oven will stay at the
starting temperature after a programmed run has begun.
Rate The rate in °C/min at which the oven will be heated or
cooled.
