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.
You can also do this using the touchscreen. See "Turn Channels On/Off
and Open Scale/Offset Dialogs" on page 54.
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 84).
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 335.
To adjust the vertical position
1 Turn the small vertical position knob ( ) to move the channel's
waveform up or down on the display.
You can also make this adjustment using the touchscreen. See "Change
Waveform Offsets By Dragging Ground Reference Icons" on page 51 and
"Turn Channels On/Off and Open Scale/Offset Dialogs" on page 54.
