The range of the vertical scale is dependent on the current probr ratio (set by

you can only set the vertical scale in 1-2-5 step, namely 1mV, 2mV, 5mV, 10mV, …,
10V. When the fine adjustment is on, you can 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.
Return
Format
The query returns the vertical scale in scientific notation.
Example
:CHANnel1:SCALe 1 /*Set the vertical scale of CH1 to 1V*/
:CHANnel1:SCALe? /*The query returns 1.000000e+00*/

Explanation
Setting probe ratio refers to multiply the signal sampled with the specified ratio and
then display the result (the real amplitude of the signal will be not affected).
Setting probe ratio will affect the range of current vertical scale.
Return
Format
The query returns the probe ratio in scientific notation.
Example
:CHANnel1:PROBe 10 /*Set the probe ratio to 10*/
:CHANnel1:PROBe? /*The query returns 1.000000e+01*/
