Test Mode T6 - Performance Test
When in this mode, the user can verify the pump and valve performance, pressure delivery, and the airflow through
the pneumatic circuit. In manufacturing, this test is conducted with known volumes connected to the sleeve s. Then
the inflation cycles run during the test at the low and high pump speeds create backpressures in the volumes that are
measured and used to verify system performance.
