Zoom
The Zoom (magnifying glass icon) menu option displays the zoom dialog. The
zoom dialog provides a magnified view of the tympanograms 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 waveforms 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.
The Set Peak button marks the current point indicated by the cross hairs, as the
peak on the tympanogram. The values are transferred to the tympanogram result
table. The Set No Peak button unmarks any peak. The Find Peak button uses the
built in algorithm of the device to find the peak. The Admittance button in the
zoom dialog selects the admittance component to view. The Close button closes
the dialog and returns to the Tympanometry screen.
