I think they need to confirm the problem and fix it. It works great in the US for 120/240V split phase – measures real power. But based on what I’ve read here, I’m afraid to use this in a commercial 3 phase 208V/120V US setup. Need them to clarify what it does in that setup.
In the US our 3 phase is Y type (3 phases and center common), but there are several forms of 3 phase across the world (such as Delta). Here is a link that describes some of the many types. Emporia is specific that only 3 phase 4 wire Wye is supported, whereas Delta is not. I wonder what specific 3 phase type you have.
Electrical Service Types and Voltages
Another possibility is that Emporia is purposely showing apparent power for 3 phase because that is how commercial customers are often billed. But not always (there is some 3 phase for high-end residential), so it needs to be configurable.
