Getting to Know the Vertical System

As shown in the figure below, there are a group of buttons and knobs in
the vertical control zone. The following exercise will guide you through
vertical setup.
Figure 1-9 Vertical control zone on the front panel
1. Turn the vertical position knob to display the signal in the centre of
the window. The vertical position knob controls the vertical
display position of the signal.
When you turn the vertical position knob, the sign indicating the
[GROUND] channel will move up and down with the waveform.
Measurement Tips :
If the channel coupling is DC, you can measure the signal's DC%
quickly by checking the difference between the waveform and
signal ground.
In the case of AC coupling, the DC% within the signal will be
filtered. With this coupling mode you can display the AC% of the
signal with higher sensitivity.
Shortcut key for resetting to zero :
[SET TO ZERO]
This shortcut key can reset vertical shift, horizontal shift and holdoff
to the zero position (center point), and set the trigger level to 50%.
