Enter the time (Final time 1) the oven is to hold Final
6
temperature 1.
To end the oven ramp program after Ramp 1, set Rate 2 to
7
zero.
Multiple ramps
In a multiple-ramp program, Final time for one ramp is also Initial
time for the next ramp. Thus, there is only one Initial time.
Set up the first oven ramp as described in "Single ramp".
1
Enter the rate (Rate 2) at which you want the oven
2
temperature to increase for the second oven ramp.
Enter the final temperature (Final temperature 2).
3
Enter the number of minutes (Final time 2) that you want the
