Speed:
The rate of change of air pressure may be selected to be 100daPa/s
200daPa/s or 300daPa/s. This determines the time taken for a pressure
sweep from +200 to -400 daPa (6, 3 and 2 seconds, respectively).
200 daPa/s
Probe Freq:
The probe tone frequency may be set to 226Hz or 1000Hz.
226 Hz
Baseline:
The Otowave 302+ can display tympanograms in a variety of graphical
formats allowing the operator to choose the most appropriate for the
patient under examination.
Please refer to the appendix for further
information on how to use the Baseline mode.

Sequence:
Define the order in which the ears are to be tested when
BOTH
ears are
to be tested in one session.
Right - Left
Ear Seal:
The
STANDARD
option is adequate for most tests, although it may not
always be possible to generate the extremes of pressure during a
tympanogram measurement with this setting.
If difficulty is experienced in using the ear tips to create a seal the
alternative
EXTENDED
option may be helpful. This function checks that a
range of pressures will be available before starting a test by means of a
visual indication of the quality of the seal.
The
EXTENDED
function is especially helpful if small ear canal volumes
should not experience excessive pressure.
Standard
Defaults:
Reset the sweep settings of the selected profile(s) to its original settings.
Copy:
Overwrite the sweep settings of your current profile from one of the other
5 profiles. Refer to section 4.4.3 for further information about the
Copy
function.
