Calibration how to

[drybrdl]

Hi, is it possible to add a small "how to" for the calibration to the readme file. The link in the app for the Current_Transformer_Conditioner calibration doesnt really make much sense as its not the same device. Im sure a quick "how to" for working out your settings would be helpful to alot of people including myself

Thanks for the great work

Ok, when I have a bit little time, I update the readme with the calibration section. The best value for the calibration is the average consumption of your house or devices that you monitor.

with a 100A SCT-013 (I think it's 000), what value should I set as ICAL? thanks

@wladimir79 you can view the ICAL value in http://lechacal.com/wiki/index.php/Current_Transformer_Conditioner

I saw this link, but I did not know whether to take the value for 3v or 5v sorry

[alcar21]

My apologies, It's value of 5v.
