Transformer Output, Current/Current
When a current clamps transformer is connected to the multime-
ter ( mA/A input), all current displays appear with the correct
value in accordance with the selected transformation factor. The
only prerequisite is that the current transformer is equipped with
at least one of the below listed transformation factors, and that
the factor has been previously selected in the following menu
(
Cl
ip
0FF
)
, see also chapter 6.4.
