The primary rating of the auxiliary current
transformer
dc.OF DC voltage zero
offset
0-9999 (0
∗) The reading of the DC voltage corresponding
to a zero DC voltage input
dc.FS DC voltage full scale
reading
0-9999 (20,
100, 300
∗)
The reading of the DC voltage corresponding
to a full-scale DC voltage input. By default it is
set to the DC full-scale input (20, 100 or 300
