Operation

Check system functions and your understanding of the system by following these steps with an empty thermal enclosure before installing the product to be tested.

1.Verify that all utilities are on-line before operating equipment. Liquid nitrogen is required for proper cooling.

These requirements are listed in the Specifications section.

2.With all function switches in OFF position, connect power to the chamber.

3.Be sure chamber enclosure door is closed securely.
