display amplitude of the waveform. The scale information of the channel status label
at the bottom of the screen would change accordingly.
Vertical
Scale
The adjustable range of the vertical scale is related to the current probe ratio. By
default, the probe ratio is 1X. In this case, the adjustable range of the vertical scale is
from 500 μV/div to 10 V/div.
When CH1 is turned on and activated, you can adjust the vertical scale in the
following ways.
• Rotate the Vertical
SCALE knob to adjust the vertical scale (clockwise to
reduce the scale and counterclockwise to increase).
• Enable the touch screen function, and then adjust the vertical scale with the
pinch & stretch gesture on the touch screen. For details, refer to descriptions in
Pinch&Stretch
.
• In the
Vertical menu, click or tap the icon at the right side of the input field of
Scale to increase or decrease the scale value or use the corresponding
multipurpose knob on the front panel to set the value. You can also click or tap
the input field to input a specific value with the displayed numeric keypad.

In the Vertical menu, click or tap the Fine on/off switch to toggle between ON (fine
adjustment) and
OFF (coarse adjustment). The default setting is OFF. You can also
press the Vertical
SCALE knob to toggle between "coarse adjustment" and "fine
adjustment".
• Fine adjustment: Use the icons at the right side of Scale or rotate the knob to
further adjust the vertical scale within a relatively smaller range to improve
vertical resolution. If the amplitude of the input waveform is a little bit greater
than the full scale under the current scale and the amplitude would be a little bit
