NOTE: To test children with PE tubes, the AutoStart needs to be
disabled. This is accomplished by first inserting the probe with
appropriate eartip into the ear canal and obtaining a proper
seal. To disable AutoStart at the main menu select the ear to be
tested by holding down the
LEFT or RIGHT
arrow keys for 3
seconds until the green ‘TEST’ light turns off. Once the key is
released, the ERO•SCAN
®
will calibrate and test as before.

Calibration and Test
The ERO•SCAN
®
instrument will automatically perform a
calibration prior to the start of each test. During calibration a
series of tones will be presented to the ear canal to calibrate the
levels of the frequencies to be tested.
Following calibration of the test tones, the test phase will begin
automatically. During the test phase, a set of bars should
appear on the Display (Display 6). These are the test results
which are displayed as the
emissions
are measured and can be
reviewed after the test is complete. Each column represents one
test frequency (DP) or frequency band (TE).
The ERO•SCAN® allows the user to select from two options for
viewing the results. The (SNR) graph view (Display 6) shows the
signal-to-noise ratio for each DP test frequency or TE test band.
The Value graph view (Display 7) shows the absolute emission
and noise levels for each DP test frequency or TE test band. For
additional information review the section
Interpreting Results on
page 30.
Testing is complete when the green ‘READY’ light is illuminated.
Both the tester and patient should remain as still and quiet as
possible until the green light turns on.
NOTE: The
UP arrow key can be used to abort a test in
progress. No record of an aborted test will be saved in memory.
