Preparing for testing AccuScreen PRO User Manual
5. Regardless of the type of test you have selected, you must
select the ear on which you wish to start the test.
Fitting the eartip in the ear canal
1. To fit the probe, gently pull the pinna back and slightly down
and insert the probe, twisting it slightly as you insert it.
Make sure that the probe fits well. Any leakage may increase
the test duration because of distortion and excessive noise.
Note:
Make sure that the cable is not in contact with any vibrating
surfaces during testing.
You can easily compensate for spontaneous movements of the
head by reducing the pull on the probe cable. To do so, form a
big loop, which you hold loosely with one hand close to the
head of the patient.
2. If you have selected an ABR test, you must also fit the elec-
trodes correctly. See
Section 5.5.1, ‘Placing electrodes for ABR
testing” on page 35 .
See Section 6.1, ‘Test methods” on page 41 on how to proceedwith
the specific tests.
