Step Description
1 Establishes a recommended initialization step. Goes to +23ºC as quickly as possible.
2 Goes to -40ºC as quickly as possible.
3 Will hold for 30 minutes. Time will not start until chamber reaches -37ºC (within the 3º Guaranteed Soak Band*).
4 Goes to +85ºC as quickly as possible.
5 Will hold for 30 minutes. Time will not start until chamber reaches +82ºC (within the 3º Guaranteed Soak Band*).
6 Jumps back to step 2. Repeats this 3-times, for a total of 4-cycles.
7 After all cycles are completed, establishes the condition to end on. Goes to +23ºC as quickly as possible.
8 Holds at +23ºC indefinitely, until program is manually stopped.
Profile Summary: +50ºC to 0ºC, 1ºC/minute ramp, 1 hour soak time, 100 cycles. Test sample turned ON/OFF depending on step. End with return to +23ºC manual set point.

Step Description
1 Establishes a recommended initialization step. Goes to +23ºC as quickly as possible. Test sample is turned ON via Event 1.
2 Goes to +50ºC at a controlled rate of 1ºC per minute. Test sample is turned ON via Event 1.
3 Will hold for 1 hour. Test sample remains ON via Event 1.
4 Goes to 0ºC at a controlled rate of 1ºC per minute. Test sample is turned OFF via Event 1.
5 Will hold for 1 hour. Test sample remains OFF via Event 1.
6 Jumps back to step 2. Repeats this 3-times, for a total of 4-cycles.
7 After all cycles are completed, establishes the condition to end on. Goes to +23ºC at a controlled rate of 1ºC per minute. Test sample is turned OFF via Event 1.
8 End of program. Controller returns to a +23ºC manual set point.. Test sample is remains OFF via Event 1.
Notes
* Guaranteed Soak Band is set at the factory for 3.0ºC. Can be changed in the System Menu.
