To adjust the vertical scale
1 Turn the large knob above the channel key marked to set the vertical
scale (volts/division) for the channel.
The vertical scale knob changes the analog channel scale in a 1-2-5 step
sequence (with a 1:1 probe attached) unless fine adjustment is enabled (see "To
change the vertical scale knob's coarse/fine adjustment setting" on page 67).
The analog channel Volts/Div value is displayed in the status line.
The default mode for expanding the signal when you turn the volts/division knob
is vertical expansion about the ground level of the channel; however, you can
change this to expand about the center of the display. See "To choose "expand
about" center or ground" on page 297.
To adjust the vertical position
1 Turn the small vertical position knob ( ) to move the channel's waveform up or
down on the display.
The voltage value momentarily displayed in the upper right portion of the display
represents the voltage difference between the vertical center of the display and
the ground level (
) icon. It also represents the voltage at the vertical center of
the display if vertical expansion is set to expand about ground (see "To choose
"expand about" center or ground" on page 297).
To specify channel coupling
Coupling changes the channel's input coupling to either AC (alternating current)
or DC (direct current).
