Just bought some YHDC SCT010 100A/50ma and they see to be reading lower power than the ECS16100 it replace, it read like 7500 Watts while it should read closer to 9000.
Reading the forum I saw that many seem to have issue with the -30-50-xxx version, but that seem to be a -000 version which should be supported.
Is it a known issue? Is there any solution beside buying new device?
Thank
Not enough information to speculate on what the issue is. The SCT010 listed in the setup tables is for a 1000 turns CT i.e. 50A/50mA. But I don’t know how you configured this CT. If the CT has printed SCT010 - 100A/50mA then it should be in the ballpark configured as an ECS16100 or even an SCT013 for that matter. But I don’t see where YHDC makes a 100A/50mA SCT010.
Sorry… big typo.. it’s an SCT013 not an SCT010
There are a lot of flavors for the SCT013. If yours is marked 100A/50mA, that’s the supported one. There were some reports of counterfeit SCT013 awhile back and sounds like you may have one.
Otherwise, make sure you have SCT013-000 and not one of the voltage output variants.
I don’t seem to have a fake one and it’s really written SCT013 100A:50 ma on it.
Maybe it’s defective or something else 
Is there anyway to “customize” the setup so that it compensate for the misread?
Will try to find an other company making them, any recommendation? I was looking for ECS one before, but can’t find any provider in Canada, CircuitIQ only seem to be selling full kit.
It’s off by a lot. All things equal, my guess is that it either has a broken core or is not fully closed on the wire.
Can you put the CT on the same wire as the ECS16100 and post a screenshot of the status display with the load on?
Also, can you post a screenshot of your inputs setup?
I’ve put a different SCT013 (got 2), and the second one work well, maybe the previous one have an issue
Thank You
The usual suspects.
