Acti 9 iEM3255 rogowski coils

[vla]

Hi there,

Can I change the CT ratio uV/kA/Hz to a different value other than the standart 1167 on a Acti 9 iEM3255?

Hi @vla 

No, you cannot change the 1167 µV/kA/Hz value because it is a fixed physical property of the Rogowski coil, not a configurable setting in the meter.

Please note that, iEM3255 does NOT support Rogowski coils and it only works with standard external CTs (1 A or 5 A). Rogowski coils require meters with an integrator circuit to interpret their voltage signal, which iEM3255 does not have.

Models that support Rogowski coils include iEM3555, iEM3565, and some iEM3400/iEM3500 series variants.

Best Regards,
