Collected data can have a wide variety of gains. Some have very large amplitude and others have very small amplitude. At this time, it is possible to adjust the amplitudes for better observation by use of gain adjustment. With the dial button as in the picture shown below, gain can be adjusted. With the mouse located at the end of the arrow mark and the left button of the mouse pushed down, you can adjust gain by dragging the mouse to the position you wish to set. By use of this button, the amplitude can be adjusted in 32 steps.
