I see two 5.1 Ohm burden (bias) resistors are built in to the input circuit

Does it matter if I select voltage ouput, or current output CT clamps? i.e. do the 5.1ohm resistors need to be cut if I use a voltage output CT clamp?

Is there a calibration routine? I will be using ESPHome.

Maybe there is a user manual for Nx that explains this?

Thank you

Yes, you are right. acutally if you use "voltage" output sensor, also can work well, just accuracy is slightly affected.
you not need to calibration. the ARM cpu already do it. if you want do it, just modify yaml in ESPHome, multiplied by a coefficient.
we suggest you download KCS v3 firmware, here is online guide details: https://www.kincony.com/how-to-use-kcsv3...meter.html
