The :DIFFzone:RANGe command sets the comparison range of the Diffzone comparator.
The :DIFFzone:RANGe? query returns the current comparison range of the Diffzone comparator.
Command syntax: COMParator:DIFFzone:RANGe <start pot, end pot>
Where,
<start pot> start point of comparison range. NR1 format, range from 0 to 6000, without unit.
<end pot> end point of comparison range. NR1 format, range from 0 to 6000, without unit.
For example: WrtCmd(“COMP:DIFF:RANG 0,960 ); set the comparison range from 0 to 960.
 NOTE: The end point value should be larger than that of the start point; otherwise an

 NOTE: Here <value> is a percent value, for example, input 2.5 for 2.5%.
Query syntax: COMParator:DIFFzone:DIFFerence？
