A chamber is used to test the temperature cycling effect on the personal
computers. An external cycle timer is used to control the event input for
switching the set point. The products under test are required to stay at 60 C
for 1 hour and -10 C for 30 minutes. The transition interval between high-low
temperature is required to be 5 minutes. Make the following setup:
