These parameters specify the setting range of the SV. You can set
any value within the measurement range.
Setting range
0 to 100%FS
The relationship between SV limits and the measurement range
is as shown in the right gure:
Set [P-SL], [P-SU], and [P-dP] before setting SV-L and SV-H. (see page 43 to 45)
SVs set before setting the SV limits (Local SV, etc.) are affected by new SV limits.
Make sure to set the value of [SV-H] greater than [SV-L].
