Hello, I got a EmonTX Shield, and mounted it and I’m using it in a Arduino UNO. I think that my shield is damaged. The CT1 and CT2 report correct readings, but the CT3 and CT4 are WAY off chart, The CT3 reports over 4000w when the load is only 200w, and the CT4 reports are also off. I calibrated CT1 and CT2, but for CT3 and CT4 the values are impossible to match.
,Can my EmonTX Shield be damaged? If so I assume that it’s from factory, because I only used it once.
Thank you all
