I just recently setup my GEM and DB and am getting the wrong readings off one of my two CT-200s. One is correct (measured against my fluke clamp meter), other is reading consistently 56.2% low. Both are configured the same in GEM Channels.

Thanks,
Nathan

Hello Nathan,

1. Is the 200 split CT monitoring a 240 circuit?
2. Are each CT's inserted into their (own) GEM channel or wired together?
3. What is the reference load you're measuring?
4. Please post up some of the CT settings in the GEM's advanced tab here for review.
5. If you review the power readings in the GEM's set up page are they correct vs the DB?

Lol, I had it wired as a type 2 instead of type 1 CT. It works fine now.
