Using CST-1020

RIDDICK:
uhm
why do u take the RMS value (it contains square values)?
Root mean square - Wikipedia

i think the arithmetic mean would b the right value...
Arithmetic mean - Wikipedia

have u seen this:
http://arduino.cc/forum/index.php/topic,125952.0.html ?

I'm working in AC. If I use the aritmetic mean i get zero or something near zero...

I have just found that topic. I will try ti find something there too.

Thanks
