The instrument automatically scales the Ax+B waveform to keep the same relative size and
position on the waveform; otherwise, a large or small gain in the transform might make the
waveform unreadable. For example, in the image below, the waveform's gain of 20 has caused
the display scale and offset to change to 100 A and 140 A, respectively.
