:CHANnel<n>:SCALe
Command format：
:CHANnel<n>:SCALe {<scale> | UP | DOWN}
:CHANnel<n>:SCALe?
Functional description：
Set voltage base in vertical position.
<scale>
：
voltage base value
；
UP
：
plus one position based on the current position
；
DOWN
：
minus one position based on the current position.
Return format：
Query return the current voltage position value by scientific notation method, unit is V.
For example：
:CHAN1:SCAL 20V
set channel 1 voltage base as 20V
:CHAN1:SCAL?
query return 2.000e001
:CHAN1:SCAL UP
plus one position based on 20V voltage base
