9.7.1 Section duration
Section view (partial view).
Select the field “Duration” indicating the time.
“Duration” entry menu.
Enter the desired section duration with the arrow keys
and press the Confirm icon.
Setting range: 0 up to 99 hours 59 min 59 sec.
9.7.2 Set-point ramp and set-point step
You can define the type of temperature transitions for each individual program section.
“Ramp” mode: Gradual changes of temperature
The set-point of a given program section functions as the section’s start temperature. During the section’s
duration, the set-point gradually passes to the set-point of the subsequent program section. The actual
value follows the continually changing set-point.
If the last program section is in “ramp” mode and the setpoint shall change within this section, then you
must program an additional section (with the shortest possible section duration) to provide the target tem-
perature of the last program section. Otherwise, the setpoint would remain constant during the section’s
duration.
Programming in the “ramp” mode allows all kinds of temperature transitions:
• Gradual changes of temperature
The setpoint changes its value gradually during the entered section duration. The actual value follows
the continually moving set-point at any time.
• Program sections with constant temperature
The setpoints (initial values) of two subsequent program sections are identical; so the temperature re-
mains constant during the entire duration of the first program section.
• Sudden changes of temperature
Steps can be programmed in ramp mode as temperature changes (ramps) that occur during a very
short interval. If the duration of this transitional program section is very short (minimum entry 1 sec),
the temperature change will proceed rapidly within the minimum amount of time.
“Step” mode: Sudden changes of temperature
The set-point of any program section functions as the section’s target value. At the start of the program
section, the unit heats up or cools down the chamber with the maximum speed to reach the entered value;
and then it holds it for the remaining section time. Therefore the set-point temperature remains constant
for the section’s duration. These changes occur rapidly within the minimum amount of time (minimum
entry: 1 second).
