• Turn the vertical position knob to change the vertical position of the waveform
on the screen.
Notice that the ground reference symbol on the left side of the display moves
with the waveform.
• Push the vertical position knob to “zero” the ground reference (in other words,
move it to the center of the screen).
Notice that, as you adjust the vertical position, a message showing the position of
the ground reference relative to the center of the screen is temporarily displayed in
the lower left-hand corner of the screen.
To specify channel coupling
1 If the channel’s menu is not currently displayed, press the channel key ( [1] , [2] ,
[3] , or [4] ).
2 In the Channel menu, press Coupling .
3 Continue pressing the Coupling softkey or turn the entry knob to select
between:
DC Passes both DC and AC components of the input waveform to
the oscilloscope. See Figure 16 .
You can quickly measure the DC component of the waveform by
simply noting its distance from the ground symbol.
AC Blocks the DC component of the input waveform and passes
the AC component. See Figure 17 .
This lets you use greater sensitivity (amplitude/div settings) to
display the AC component of the waveform.
GND The waveform is disconnected from the oscilloscope input.
