Change the vertical setup and observe changes
of status information. You can identify changes of
any vertical range by reading the status display
column at the lower corner of the waveform
window. Turn the vertical

You will
find that the range in the current status
column has changed accordingly
Press

Measurement Tips :
If the channel coupling is DC, you can measure the
signal s DC component quickly by checking the
distance between the waveform and signal
ground level
In the case of AC coupling, the DC
of the
signal will be blocked. With this coupling mode you
can display the AC
of the signal with
higher sensitivity
