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 62).
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 251.
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 251).
To specify channel coupling
Coupling changes the channel's input coupling to either AC (alternating
current) or DC (direct current).
