Define your program as a series of setpoints with a known period of
time interval between each. Each interval is one step of the program. Pay
careful attention to the first part of your program. What conditions must
exist at the beginning of your process? For example, at the starting set-
point you may need to program an initial period of constant temperature
to allow for thermal stabilization.
Note Consider the circulator's limitations when designing programs.
Temperature or time parameters which exceed the performance capabili-
ties of the circulator will result in unsatisfactory operation. If reaching
the ramp setpoint temperatures is important, you will have to operate the
bath between the desired setpoints and note the duration before pro-
gramming the ramp.
It is possible to create a program calling for very rapid changes in tem-
perature. Although the circulator may not be capable of producing such
changes, it may be practical to program such steps as a way to cause the
fastest possible temperature change.
