RIGOL 2 To Set the Vertical System

Vertical Scale
The vertical scale can be adjusted in “Coarse” or “Fine” mode.
Press CH1  Volts/Div to select the desired mode. Rotate VERTICAL SCALE
to adjust the vertical scale (clockwise to reduce the scale and counterclockwise to
increase).
The scale information (such as
) in the channel label at the bottom
of the screen will change accordingly during the adjustment. The adjustable range of
the vertical scale is related to the current probe ratio. By default, the probe ratio is 1X
and the vertical scale range is from 1 mV/div to 5 V/div.
 Coarse adjustment (take counterclockwise as an example): set the vertical scale
in 1-2-5 step namely 1 mv/div, 2 mV/div, 5 mV/div, 10 mV/div…5 V/div.
 Fine adjustment: enables fine adjustment to the vertical scale. If the amplitude
of the input waveform is a little bit greater than the full scale and the amplitude
would be a little bit lower if the next scale is used, fine adjustment can be used
to improve the amplitude of waveform display to view signal details.
Note: You can also press VERTICAL
SCALE to quickly switch between “Coarse”
and “Fine” adjustments.
