Related to the probe ratio

When the probe ratio is 10X: 80mV to 800V 
8V (the probe

This command indirectly modifies the vertical scale of the specified channel (Vertical Scale 
= Vertical Range/8). The vertical scale can be set by the :CHANnel<n>:SCALe command. 
The query returns the vertical range in scientific notation. 
:CHANnel1:RANGe 8          /*Set the vertical range of CH1 to 8V*/ 
:CHANnel1:RANGe? /*The query returns 8.000000e+00*/
