Tip
Do not confuse this
Gain
Description
You can compare this gain setting with the volume
control on your car radio. When the gain is increased,
the echoes will appear stronger. Weak echoes will
be easier to see. However, since you also increase
the acoustic noise in the reception, the EK15 echo
presentations will also show this. Too much gain will thus "distort" the presentation.
By default, the gain setting applies only to the currently selected echogram (identified
with a thick border). Several echogram types are available, these are selected in the
dialog box. If you wish to adjust the gain on all similar echograms in your
Echogram
view, click to select

Tip
If you open this menu button, you will only be able to enter a value if a computer
keyboard is connected to your EK15. However, you can click the button, hold the mouse
button depressed, and then move the mouse – and cursor – sideways. This allows you
to change the parameter value. You can also adjust the setting by clicking and holding
either the [+] or [-] buttons.
