Auto scale

Auto scale is a function in the EEG monitor window. EEG signals should be displayed completely inside their track. Sometimes the amplitude is too high and the signal exceeds the height of the track. In extreme cases, the signal can be completely outside the window and is therefore invisible.

If any part of a signal exceeds its track, a warning is displayed in the window header and additionally the right part of the window shows a red background color. The user can reduce the signal amplitude manually with the mouse wheel. An alternative is the auto scale function, which adjusts the amplification of the signal so that the largest amplitude in the visible area of the window is 90% of the height of the track.

There are two ways to trigger the auto scale function
 * The command is available in the context menue of the EEG monitor (See picture)
 * As a shortcut, the function can also be triggered by a double click to the left mouse button in the red area at the right side of the window
