9 Testing with Zodiac Diagnostic or Clinical -
Stand-Alone
Zodiac Diagnostic or Clinical performs tympanometry which
can be combined with diagnostic reflex tests such as threshold
and decay measurements .
These measurements can be performed manually, auto-
matically or in a sequence of tests with the option of using mul-
tiple probe tones.
An additional range of features is described in detail in the
MADSEN Zodiac Reference Manual.
Zodiac has two probe connections which make it possible to
choose between using a Quick Check probe for fast tym-
panometry, and a diagnostic probe for more detailed meas-
urements.
9.1 Quick Check testing
You can perform Tympan Reflex Screening as a sequence from the Tympanometry test screen.
When seal is obtained, i.e. when the screening eartip is pressed gently against the ear, the test starts with tympanometry
testing and continues automatically from tympanometry to reflex screening.
Note
•
The safety intensity level cannot be exceeded in screening mode.
Note
•
You can use either ordinary eartips or screening eartips for screening.
Preparing for testing
1. Do as described in

►

.
2. Ask the patient to sit very still and quiet during the test, without moving head or jaw.
3. If needed, toggle the
Ear Selector
to select the ear on which you wish to start the test.
4. Continue as described in
Starting a measurement ► 48
.
9.1.1 Starting a measurement
To prepare for the test before you start testing, see Preparing for testing ► 36 .
1. Look into the ear canal. It is strongly recommended that you perform an otoscopy to assess the status of the outer ear
before you insert the probe.
2. If the ear canal is blocked, this may affect the result of the test. Clean the ear canal if needed.
Caution
•
The probe can be damaged if fluids enter the probe.
