Question about the energy monitor with arduino

Submitted by Guest on Sun, 29/01/2012 - 17:37

Hello,

I read the source code and there is lot of things I don't understand :

#define AC_VOLTAGE_DIV_RATIO 11. What is it ?

numberOfSamples

What is it Ical and Vcal ?

double V_RATIO = RATIO_TANSFORMATEUR * AC_VOLTAGE_DIV_RATIO * 5 / 1024 * VCAL;
double I_RATIO = (long double)CT_TURNS / CT_BURDEN_RESISTOR * 5 / 1024 * ICAL;

Why 5*1024 ?

Thanks
