The

indicating its value with respect to the ground reference located at the center of the
screen. Also notice that the ground symbol on the left side of the display moves in
conjunction with the

Measurement hints
If the channel is DC coupled, measuring the DC component of the signal by
simply noting its distance from the ground symbol.
If the channel is AC coupled, the DC component of the signal is blocked, allow
you to use greater sensitivity to display the AC component of the signal.
