1. A method for testing a system for controlling pressure within an enclosure comprising the steps of:

  • producing a first electrical signal to simulate pressure within the enclosure;

    producing a pneumatic signal that corresponds to the electrical signal;

    operating a pressure control system that is being tested responsively to the pneumatic signal;

    producing a second electrical signal responsively to the operation of the pressure control system; and

    monitoring the second electrical signal against a known performance standard to determine if the pressure control system functions correctly.
