Has anyone used this Current Transfomer?
SCT013

I get a weird output from it.

With a True RMS meter clamped on the same load,
the True RMS meter shows 10A
and the SCT013 shows 7.4A
(no problem here, I suppose)

But lowering the load to 4A (shown on the True RMS meter), the SCT013 shows 5.2A
(that's my problem, I'm expecting a reading lower than 4A, to have the same kind of ratio as at the higher load)

What trickie calculations do I have to do to get the ratio right?

Hi,

You can see the example code for our AC Current click which uses the SCT013 sensor in the link below:

All the calculations are in the source files.

Thanks,

Do you do an AC Click board for at least 2x CT SCT013 sensors?

Hi,

Unfortunately we do not have a click board which uses 2 SCT013 sensors at the moment.
