This aim of this example is to show you how it is possible to influence the
temperature profile of a program by changing individual segment settings.
The graphic opposite shows the original profile with a solid line, and the
edited profile with a dotted line. The cooling duration (segment 6) varies
depending on the type of device, application and other factors; it is shown by
dashed lines.
The original profile (solid line) roughly shows three sequence phases; the
values defined for them can be seen in the table below:
Segment 1: The start temperature 30 °C is maintained for 20 min.

Segment 2 – 4: The temperature is increased in 2 phases to 70 °C within

an hour, and then maintained for 10 min.
Segment 5 – 6: The temperature is increased to 60 °C within half an

hour and should then reduce to, and be maintained at, 40 °C without a
time limit, i.e. as quickly as possible.

- Removes the currently selected segment (segment
number with a light background) from the program
sequence.
- Reverses the last delete operation.
- Inserts a copy of the currently selected segment into
the next line.
- Displays the temperature-time diagram of the pro-
gram sequence created so far (all segments).
