Setting coupling channel

The following example shows how to change the coupling
of the input channel. If the measured signal connected to the
CH1 channel is a sinusoidal signal containing DC component,
press F1 to select AC coupling, to set the CH1 into AC
coupling mode. The DC component of the measured
signal is blocked.
The Waveform display is shown in the figure below.

If you press F1 to select DC coupling, setting both
the DC and AC components of measured signals at
