The current input of the instrument may connect directly to
the power network (Iin < 5 Aeff [nominal]), or through a
current transformer (Iin > 5 Aeff [nominal]).
When you connect the input directly you should set CT=1.
When you connect the input through a current transformer
you should set the CT ratio of the applied transformer, so
the instrument able to compute with the primary current.
(e.g. 100/5 A/A, CT=20)
