The following operations are available in manual mode.
In the tymp test:
Press the Record button to start recording the tympanogram.
Press the Stop button to stop the recording of the tympanogram.
Press the Release Pressure button to have the pressure released
and brought back to 0 daPa.
During manual testing, the pressure cursor is dragged by the
mouse and changes the desired pressure.
The measurement trail shows what the (non-compensated)
acoustic admittance is. It is only shown when not recording. If you
choose to view the compliance compensated for the equivalent ear
canal volume, it is only shown after the recording is finished
because only then the compensation value can be correctly used.
In other words, during recording the display will always be non-
compensated.
In the reflex, reflex decay and reflex latency tests:
Choosing At peak results in using the peak pressure of the last
available tympanogram with the same probe tone frequency.
Choosing 0 daPa of course results in a measurement at zero
pressure.
Choosing Manual results in having items 3 to 5 available for setting
the pressure manually.
The pressure handle can be dragged by clicking it with the left
mouse button. When selected you can also use the left and right
arrows to adjust the pressure more precisely.
While changing the pressure on the pressure handle, the non-
compensated admittance is indicated as an equivalent ear volume
on the volume bar.
This Start (and Stop) button is used to start and stop the manual
pressure changing. When stopped, Titan will try to keep the
pressure constant.
With the duration slider you can set the stimulus length to 10, 15,
20, 25 or 30 seconds during manual reflex decay testing.
The Manual stimulus button becomes active when manual testing
is selected in a reflex test. After the Manual stimulus button is
pressed, the cursor changes into a speaker. When clicking on one
of the graphs, the reflex measurement is started. When clicking
again it will stop the measurement (Which is, e.g., used if the
measurement does not start correctly due to a bad probe fit).
