Waveform Invert
When waveform invert is enabled, the waveform display rotates 180 degree relative
to the ground potential. When waveform invert is disabled, the waveform display is
normal. Press CH1 Invert to enable or disable waveform invert.
Vertical Scale
The vertical scale can be adjusted in “Coarse” or “Fine” mode.
Press CH1 Volts/Div to select the desired mode. Rotate VERTICAL

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 probe ratio currently set. By default, the
probe ratio is 1X and the adjustable range of the vertical scale is from 500 μV/div to
10 V/div.
Coarse adjustment (take counterclockwise as an example): set the vertical scale

Fine adjustment: 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 lower if the next scale is used, fine adjustment can be used
to improve the amplitude of waveform display to view signal details.
