9.3.6 Set-point ramp and set-point step modes
“Ramp” mode
The set-point of a given program section functions as the section’s target temperature. During the section’s
duration, the temperature set-point gradually passes from the set-point of the previous program section to
this target set-point. The actual temperature value follows the continually changing set-point.
Programming in the “ramp” mode allows various kinds of temperature transitions:
• Gradual slow temperature changes
The set-point changes its value gradually during the entered section duration. The actual temperature
value (X) follows the continually moving set-point (W) at any time.
• Constant temperature
The initial values of two subsequent program sections are identical; so the temperature remains con-
stant during the duration of the first program section.
• Sudden temperature changes
These changes occur rapidly within the minimum amount of time (minimum entry: 1 second).
“Step” mode
The set-point of a given program section functions as the section’s target temperature. At the start of the
program section, the chamber heats up or cools down with the maximum speed to reach the entered value;
and then it holds it for the remaining section time. The set-point temperature remains constant for the sec-
tion’s duration.
