Getting to Know the Vertical System
As shown in the figure below, there are a series of buttons and knobs in the vertical
control zone. The following steps will get you familiar with the use of these controls.
Figure 1-9
Vertical controls
1. Turn the vertical position knob [POSITION] to enable the waveform 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 vertical reference of the [GROUND] channel will move up and down with
the waveform.
Measurement Tips
If the channel coupling is DC, you can test 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 intercepted. In this
coupling mode you can display the AC% of the signal with higher sensitivity.
Shortcut key for resetting the vertical position of the dual analog channel to
zero [SET TO ZERO]
This shortcut key can reset vertical shift, horizontal shift and holdoff to the zero
position (center point).
