Waveform Invert

Press CH1  Invert to enable or disable 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 (as shown in the
figure below).
(a) Turn Off "Invert"

Vertical Scale

Vertical scale refers to the voltage value per grid in the vertical direction on the
screen and is usually expressed as V/div.
Press CH1 and rotate VERTICAL
to reduce the scale and counterclockwise to increase). The size of the displayed
waveform will be changed accordingly. The scale information (as shown in the figure
below) 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 10X and the adjustable range
of the vertical scale is from 10 mV/div to 100 V/div.
The vertical scale can be adjusted in "Coarse" or "Fine" mode. Press CH1 
Volts/Div to switch the adjustment mode.
Coarse adjustment (take counterclockwise as an example): set the vertical scale

in 1-2-5 step namely 10 mV/div, 20 mV/div, 50 mV/div, 100 mV/div...100 V/div.
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.
