To adjust the vertical scale
When an input channel waveform is on:
• Turn its vertical scale knob to change the amplitude per division
setting.
The amplitude/div setting changes in a 1-2- 5 step sequence from
2mV/div to 5V/div (with “1X” probe attenuation).
Either ground or the center of the screen is used as a reference,
depending on the “Expand Reference” preference setting (see “To select
the vertical scale reference level” on page 136). The “center of screen”
reference is not available for math function or reference waveforms.
• Push its vertical scale knob to toggle between vernier (fine scale)
adjustment and normal adjustment.
With vernier adjustment, the amplitude/div setting changes in small
steps between the normal (coarse scale) settings.
The Volts/Div item in a channel’s menu also toggles between vernier and
normal adjustment (see “To change the Volts/Div control sensitivity” on
page 50).
Vernier adjustment is not available for math function or reference
waveforms.
The amplitude/div setting is displayed in the status bar at the bottom of
the screen.
To adjust the vertical position
Adjusting their vertical position lets you compare waveforms by aligning
them above one another or on top of each other.
When an input channel waveform is on:
• 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).
