Thankyou so much for posting this! I was considering using the pzem-004t for a personal project to measure small changes in current, and I had my doubts about the accuracies listed in the spec sheet. This has been super helpful.
Very interesting. Thank you. Double thanks for the subtitles!!!
Ein gutes Video. Vielen Dank.
Maybe accuracy differences are caused by different current density? 10 turns will have 10 times smaller current density. It definitely improves transformer efficiency, maybe somehow impact output current current too, can't find anything. You could try repeat the accuracy test with single loop of ten wires. Also, if seeking accuracy, comparison with 10A shunt version would be interesting, that should be more accurate in general.
Hello, thanks for that great video, I would just like to ask you if it is possible to access the data of the function you measured.
Great content. Kudos!
Thank you very much for this useful video.

Fantastic precision exam and very good documentation of the entire procedure, I learned many ideas and concepts from it.
Man, you are rocking. ❤️+1
HI , WHAT IS THE MINIMUM RESPONSE TIME FOR THE MODULE TO DETECT VARIATION IN VOLTAGE, FREQUENCY, A, WH? ETC
With my device, 3 out of 4 requests go unanswered and the software (any software, not just your python script) complains about the timeout.
Hey, is it possible to measure 15-100hz ac voltage with this and read kind of accurate readings?
the voltage range is 80-260V, do you think it can read 280V?
