Example profile
Gwen, of Smith Manufacturing needs to perform a burn-in test of their product in an environmental chamber. The
test should take the product through the following sequence:
1. Heat from room temperature to a temperature of 150°F over a 1-hour period.
2. Hold the temperature at 150°F for 2 hours.
3. Cool the temperature to 32°F as quickly as possible.
4. Once the temperature reaches 32°F, hold that temperature for 2 hours.
5. Stop controlling the temperature and allow it to return to room temperature naturally.
Use the master step chart to map out the profile.
