Display and Administrative Curves:

After the measurement is completed, it is possible to add comments to the curves in the file. It is also possible to show, hide, or delete curves. Further information about the measuring conditions and special single values can be added.

Edit Mode:

• No measurement is active (Figure 26)
• View values in the status bar by moving the mouse cursor in the active (yellow) space (Figure 27a-27e).

Status Bar Displays Examples:

Curve info window:

To obtain detailed information about a curve, open the Curve info window by clicking the right mouse key (Figure 28).

The Curve info window displays saved information for each curve. Additional comments for each test curve may be added in this window. 

If an RECD has been measured for one of the ears, the options to <Convert into in situ curve> or <Convert into test box curve> will be available.

Curve Display Options:

Selected curves can be edited by clicking: <insert>, <hide>, or <delete>. Target information may also be shown or hidden.

For further information, please refer to the section: "Save Window."

Curve display options may be changed using the setup menu. It is possible to switch between the output level (dB SPL) axis and the gain level (output - input) axis, line width, and more.

The display of the measurement range (i.e. the scale division of the y-axis) can be adjusted. It is possible to display levels from less than 30 dB to  greater than 140 dB.

The i/o diagram is typically displayed for input levels from 30 dB to 100 dB.

• Extending the window width increase this range from 0 dB to 100 dB.
• Changing the window height the aspect ratio is maintained according to the standard (IEC 60263) for measuring hearing aids, one decade on the frequency x-axis has the same length as 50 dB of the output level on the y-axis.

For further information, please refer to the section: "Setup."

Right-Click options (Figure 29):

Right-click the mouse anywhere on the test box screen to open a window that allows you to show, hide or delete curves.

Curves may also be exported into various formats.

• A prerequisite for a successful export is that the corresponding programs are installed on your computer.
• Exporting the files to an ASCII file will prompt a message asking where and under which name the file should be saved.

Attack and Release Times:

It is possible to zoom in on the displayed curve for the attack and release time measurements.

1. Move the mouse cursor to the preferred starting coordinate.
2. Press the middle mouse key and hold it down and move the mouse to the end coordinate of the zoom window. You may perform the zoom multiple times to increase the section window.
3. Click the middle mouse key without moving the mouse to end the zoom. The curve will be displayed in its original shape and resolution.  

Save Dialog (Figure 30):

If you have measured curves with pure tones you may overlay additional curves for comparison on the same screen.

1. Start the save dialog.
2. Select the total levels of the coupler microphone, reference microphone, harmonic levels, or the total harmonic distortion.
3. These items can only take effect when measurements were performed with pure tones and when "with FFT" was enabled in the setup menu.
