Viewing Previously Collected DPOAE Data
This flow chart begins at the point where the PERFORM DPOAE message is displayed and
shows the program flow for instances in which you wish to view data that is saved in memory.
Recall that only the last 10 tests are retained in memory for retrieval and review. Tests collected
prior to the last 10 are sequentially overwritten with each new test performed. There is no way to
retrieve them after they have been overwritten.
The PASS/REFER indicator displayed in the first SEE DETAIL box is for the overall test. The
PASS/REFER indicator in the second X KHZ DP ## box is for the individual frequency being
displayed. The displayed PASS/REFER indicator is based on research published by Gorga et al
(1997). For more information about the criteria needed for a PASS or REFER indicator to appear,
see Chapter 12 System Default Protocol.
In the X KHZ DP ## message box, the number after the DP abbreviation is the amplitude of the
distortion product emission. In the second line, the number following the word NOISE is the
amplitude of the noise floor.
Remember that RESTART will return to the PERFORM DPOAE message at any time.
