6.6  Waveform inversion  
Open Vertical channel > Invert to turn on the waveform inversion function, which is 
disabled by default. 
 
When the waveform inversion is disabled, the waveform is displayed normally. When 
waveform inversion is turned on, the voltage value of the waveform is inverted as shown 
in the figure below. Turning on waveform inversion will also change the results of 
mathematical operations, waveform measurements, and other operations.

6.7  Probe    
Open Vertical channel > Probe. 
 
The oscilloscope allows the user to set the probe attenuation ratio manually. The user 
must set the probe ratio correctly to obtain accurate measurement results. The default 
probe ratio is 1X, and the probe range is 0.01X-10000X. 
In order to match with the attenuation ratio of the probe in use, it is necessary to adjust 
the corresponding channel attenuation ratio under the channel menu. Whenever the 
probe attenuation ratio changes, it is necessary to set the corresponding attenuation 
ratio to ensure the correctness of oscilloscope waveform amplitude and measurement 
results.

Open Vertical channel > Unit. The optional units are voltage and current. The default 
unit is voltage.
