Using multiple SCT013-010 with Arduino Uno R4

Using Arduino Project Guidance

I am trying to measure the current going through two wires and for this purpose i have gotten an Arduino Uno and two SCT013-010 CT clamps.

I have looked at the resources provided in previous threads mentioning these hardware, but i have one question that i have been unable to answer myself.

I have found this wiring scheme for connecting one SCT013 to the Arduino, but i was not sure about wiring two of them. My question is: Is it possible to wire a second SCT013 to the same wire labelled "Ref. tension" with the other wire to a different analog pin than the first one? Or does each SCT013 require it own center offset circuit?

You want to save 2 resistors (and a cap)?

Try it, sharing the same resistors and with each sensor having it's own resistors. I'm pretty sure it's safe. Do you see any difference in the readings?

I will try it! Will update with results.
