TAKING MEASUREMENTS
Ensure that the appropriate settings have been made before carrying out a test. See below and the
CONFIGURATION options in Section 6,
To view the test settings ensure that the MAIN MENU is displayed and then press and hold the function button
on the probe to display the TEST SETTINGS screen as shown below.
TEST SETTINGS
Probe: 226 Hz
Reflexes: Ipsi+Contra
500 1k 2k 4k Max dB
I:
85/5
C:
85/5
Probe #: 12345
Contra #: 6789
This indicates the probe frequency being used, the reflex source selected, and the selected frequencies,
maximum level and step size of the reflex stimulus. Also displayed are the serial numbers of the probe and the
contralateral transducer.
In the above example the probe frequency is 226Hz, all frequencies have been selected for both the ipsilateral
and contralateral reflex stimuli, and the maximum level for both reflex stimuli is 85dBSPL with a step size of
5dB between the three preceding lower levels of stimulus.

PRIOR TO TESTING AND AMBIENT CONDITIONS
A suitably-qualified health care professional should perform a thorough otoscopic examination to establish that
the condition of the ear is suitable for the test options selected and that no contraindications are present. The
latter would include obstruction of the external ear canal due to excessive wax and/or hairs, both of which
would need to be removed.
Tympanometric and reflex testing should always be performed in quiet conditions.
5.2.
EAR TIP(S)
Video available on how to choose the correct ear tip.
The probe tip must be fitted with a new ear tip before it is presented to a patient’s ear canal. If a contralateral
reflex stimulus is to be applied, fit a new ear tip to the contralateral transducer before presenting it to the
patient’s opposite
ear canal.
Please note:
Never
insert the probe or the contralateral transducer into a patient’s ear canal without a
suitable ear tip fitted.
The ear tip size is chosen based on the diameter of the
external
ear canal and should suit the patient’s ear but also
provide a comfortable pressure seal.
