The probe will have an airtight fit when the indication light on the
probe is green. When the status “Leaking” or “Blocked” is displayed
in the upper right hand side of the screen the indication light on the
probe will be yellow. This indicates a bad fitting or a blocked ear tip.
When a correct fit has been obtained a tympanometric test is
automatically performed on the first ear.
2a) If clinical headset is used:
When using the clinical headset select "Pause" (9) in order
to prevent the instrument from automatically starting the
test as soon as an airtight fit has been obtained.
Now place the clinical headset over the patient's head or
use the shoulder strap and insert the probe tip into the ear
canal. When an airtight fit has been obtained the
tympanometric test is ready to be performed. To start the
test, select "Pause" (9) once again and the test will be
carried out automatically.
Note: From the Common Setup Menu it is possible to set up the
“Pause” key (9) to be controlled from the Remote Switch of the
probe.
On the screen the tymp test can be followed on-line.
3. Remove the probe from the first ear when the test
sequence has finished. Select the other ear “Right” (19) or
“Left” (20) and move the probe to the second ear and
repeat the test sequence once again.
Extend Function
In the Tympanometry mode it is possible to extend the
pressure range to go from +300 daPa to
–600 daPa by
pressing F6. When the Extend Function is active “Extend” in
lower right hand corner of the screen is highlighted.
The pressure range is indicated by two small, bold, vertical
lines on the horizontal 0 ml line. To go back to the standard
pressure range press F6 once again.
