– Otowave 102 Operating Manual
When the tympanogram is complete the instrument will perform the reflex test(s), if selected. By default this
test is only performed if a peak is found in the tympanogram. This and other reflex test options may be changed
in the CONFIGURATION menu, see Section 0.
Before starting the reflex test the ear canal pressure will be set to the value that gave the peak compliance
during the tympanogram test. The instrument will then step through the tone frequencies and levels set in the
CONFIGURATION menu searching for a reflex response.

When the measurement is complete the indicator on the instrument changes from flashing green to steady
green. The display confirms that the test has been completed along with the instruction WITHDRAW PROBE.
Remove the ear tip from the patient and after a short period the tympanogram will be displayed.
The display shows:
The peak compliance, in ml (Pk)
The pressure which gave the peak compliance in daPa
The Gradient, in daPa (Gr)
The Ear Canal Volume (ECV) in ml measured at 200 daPa.
A pass/refer sign indicating if tympanogram appears to be normal or not
A plot of compliance against pressure.

Review the tympanogram to ensure that the peak compliance point selected by the Otowave is suitable. If
required it is possible to select an alternative peak using the ▲ and ▼ keys. The figures displayed will change
to reflect the peak selected, and will be saved with the tympanogram.
