To set contrast, volume, or balance, first select the function and then use the
left and right arrow keys to adjust the level. The backlight key serves as a
toggle switch, alternately turning on and off the backlight.

Select Adjust Filters to improve the correlation when, for example, no
correlation exists or the peak is too broad. Two filters are available for
separately suppressing low and high frequencies. The High Cycle and Low
Cycle
buttons cause the selection of the high and low cut-off points. To
ensure a pass-band always exists, do not set the filters to overlap. These
settings may be applied to accelerometer inputs or to hydrophone inputs by
selecting the source with the Accelerometers/Hydrophones button.

Filters may be selected automatically using the Use Defaults button, which
selects filters for both accelerometer and hydrophone inputs.

View

The View option allows for a detailed inspection of the leak noise correlation.
Control the cursor using the left and right arrow keys.

Stop/Restart This button halts and restarts leak noise data processing.

Clear This button erases all existing information and initiates a new
correlation.

Zoom In This button expands the display, with the cursor position serving as
the central location. The scale bar below the cursor indicates the degree of
zoom by adjusting the length as the zoom varies. The Zoom Out button
reverses the zoom process.
