Abstract
A leak detection apparatus includes a test chamber and a vacuum source connected to the test chamber via a pneumatic line. A first pressure transducer is in communication with the test chamber. A controller is configured to collect and analyze data generated by the first pressure transducer at a predetermined frequency throughout an entire test cycle. The controller is also configured to convert specified collected data to logarithmic scale to accumulate a first set of data and apply a linear regression to the first set of data and determine regression parameters.
