Even though CH2 is calculated internally, it is recommended that the CT settings reflect those from CH1, rather than being left at
factory default, to facilitate configuration validation from the RTU.

Even though disabled channels are not used in calculations and report 0.0 they still contain configuration information. It is suggested
that they be set to a known value rather than left at defaults to facilitate configuration validation by the RTU.
