Table 9 PROBE CHECK Screen
Screen
Explanation
Figure 32
The ear canal volume of the patient is too large or the probe
is not inserted into the ear or in place properly (Figure 32).
Figure 33
Volume is too small for the test to begin or probe tip is blocked
(Figure 33).
Figure 34
The ear canal volume is in the target area for testing, but the
bars stay grey until the seal is also detected (Figure 34).
Figure 35
The ear canal volume is in the target area for testing and a
seal is detected. The test starts automatically (
AutoStart
) as
soon as the probe fit is stable (Figure 35).
When a seal is obtained, the device will automatically begin testing (
AutoStart
), and
the yellow LED (
TEST
) lights up during the test procedure.
If the probe check is not successful try the following:
1. Select an eartip that fits the ear canal of the patient better.
2. Try once more to place the probe (see description above).
If you can still not start the test proceed as follows:
•
Turn off the device.
•
Change the probe tube.
•
Make sure that the probe connector is seated properly in the socket.
•
Try again to start a test.
5.7.5 TEOAE and Pause Function
The ERO•SCAN
®
incorporates a pause function within the TEOAE test when a leak is
detected. When the detection occurs, all three LED lights at the top of the device
(Noise, Test and Ready) will illuminate to display the device is in pause mode. The
pause mode will wait for up to 30 seconds. This allows the tester to reposition the probe
without starting the test all over. If the seal is not able to be obtained within the 30
seconds a
No Seal
error will display and the probe should be repositioned and test
restarted.
