Multi-Hz Test Menu
Auto Start
The Auto Start check box determines if the test starts automatically upon
obtaining a seal. When the box is checked, the data collection begins as soon as
a seal is obtained. When the box is not checked, the start button on the device or
probe shoulder box is used to start a test.
Immittance
The Immittance button selects the tympanometry component(s) that is displayed
on the graph. The button label indicates the current setting. When the button is
pressed a submenu is displayed where the user may choose between the
Admittance (Y) and the two components of Admittance, Susceptance (B), and
Conductance (G) and the combined graph showing both B and G (B/G). The
default setting for the immittance for data collection is set in the Config App but
may be changed on the analysis.
Baseline
The Baseline checkbox button is used to select if the tympanogram is baseline
adjusted. When the button is selected the starting pressure admittance value is
used as a baseline (0 mmho) and the data is plotted relative to that pressure. The
default setting for the baseline for data collection is set in the Config App but
may be changed on the analysis. For Multi-Hz testing the baseline defaults to
off.
Sweep Rate
The Sweep Rate button is used to select the sweep rate (daPa/sec) for the
pressure change when collecting a tympanogram. The button label indicates the
current setting. When the button is selected a submenu of options is presented.
Age
The age button toggles between Adult and Infant. This selection affects the
calibration/compensation for the wide-band stimulus. Select Infant when
evaluating patients from birth to six months of age.
Zoom-Tymp
Zoom allows the user to review or override the selected tympanogram peak.
When a Tymp tab is selected, the Zoom (magnifying glass icon) menu option
displays the zoom dialog. The zoom dialog provides a magnified view of the
tympanogram and displays the pressure and admittance values for the selected
point. The up, down, left, and right arrow buttons are used to scroll the
waveform. The + and - magnifier buttons increase and decrease the
magnification. When multiple tympanograms are present, the active waveform
may be selected from the list of tympanogram curves on the left side of the
dialog. The crosshairs of the cursor may be moved to a different point on the
waveform by touching the waveform at the desired point or by using the manual
pressure knob on the instrument to move right and left on the waveform.
