APPENDIX A – RAMP & SOAK EXAMPLE
General
An efficient way to program a profile is to first outline what the temperature controller
should do. If the chamber has humidity control, an outline should be generated for this
too. Example of a temperature profile outline:
Profile 1
Step 1 Ramp to 20ºC as quickly as possible
Step 2 Stay at 20ºC for 2.5 hours
Step 3 Ramp to 50ºC at a rate of 1ºC per minute
Step 4 Stay at 50ºC for 8 hours
Step 5 Repeat steps one through four 6 times
Step 6 Ramp to 30ºC over a 90 minute span
Step 7 End profile continuing at 30ºC until user intervention
Once a profile is outlined, it can be entered into the controller.
1. “Unlock” the controller (if necessary) by referring to Section 14
2. Access the Profiling Page by pressing the ADVANCE key for 3 seconds.
3. Using the UP and DOWN arrow buttons, display the desired profile (Ex: P1)
Profile 1 contains steps 1 – 10
Profile 2 contains steps 11 – 20
Profile 3 contains steps 21 – 30
Profile 4 contains steps 31 – 40
4. Press the ADVANCE button once; the step should display
5. Using the UP and DOWN arrow buttons, display the desired step (Ex: 1)
6. Press the ADVANCE button once; the step type will display
7. Use the UP and DOWN arrow buttons to scroll through the step types. Below is
a description of available step types:
