To Adjust the Horizontal Position

Horizontal position, also called trigger position, refers to the trigger point position of
the waveforms of all channels in the horizontal direction relative to the center of the
display. When the waveform trigger point is at the left (right) side of the center, the
horizontal position is a positive (negative) value.
Changing the horizontal position moves the waveform trigger points and the
displayed waveforms of all channels horizontally. The horizontal position displayed in
the horizontal position label ("D" icon) changes accordingly, as shown in the figure
below.
