Step Type
Set the behavior of the step. Step Type options include:
Soak:
Maintains the temperature or humidity set point constant for the step’s Time.
•
Hours, Minutes, Seconds
(How long the step will hold at this condition)
•
Guaranteed Soak Enable 1
(Temperature)
•
Guaranteed Soak Enable 2
(Humidity)
•
Power, Humidity, Purge, Event 4 through 8
(On, Off, Unchanged from previous step)
Ramp Time:
Adjusts the temperature or humidity set point gradually from the previous set point
to the step’s Set Point over the step’s Time.
•
Target Set Point Loop 1
(Temperature)
•
Hours, Minutes, Seconds
(Time to ramp from the previous step condition)
•
Guaranteed Soak Enable 1
(Temperature)
•
Target Set Point Loop 2
(Humidity)
•
Guaranteed Soak Enable 2
(Humidity)
•
Power, Humidity, Purge, Event 4 through 8
(On, Off, Unchanged from previous step)
Rate:
Adjusts the temperature or humidity set point at the user-set Rate of change until it reaches
the step’s Set Point.
•
Target Set Point Loop 1
(Temperature)
•
Rate
(Degrees per Minute)
•
Guaranteed Soak Enable 1
(Temperature)
•
Target Set Point Loop 2
(Humidity)
•
Rate
(% Humidity per Minute)
•
Guaranteed Soak Enable 2
(Humidity)
•
Power, Humidity, Purge, Event 4 through 8
(On, Off, Unchanged from previous step)
Wait For Process or Event:
Holds the profile until the specified conditions are met. When
multiple conditions are specified, the profile will not proceed until all the conditions are satisfied
at the same time.
•
Step Wait for Process Enable 1
(Temperature) (None, Greater Than, Less Than)
•
Wait for Process 1 Value
(Temperature, if Greater Than or Less Than is selected)
•
Step Wait for Process Enable 2
(Humidity) (None, Greater Than, Less Than)
•
Wait for Process 2 Value
(Humidity, if Greater Than or Less Than is selected)
•
Power, Humidity, Purge, Event 4 through 8
(On, Off, Unchanged from previous step)
Instant Change:
Sets the temperature or humidity set point without ramping from the previous
set point and holds that set point for the step’s Time. Use this when programming the chamber to
go as fast as possible between steps.
