When I try to measure a pulse at CF output pin , I find a distorted pulse and it is constant even in the absence of load.And F1 F2 output also provide the different distorted pulse
When I try to measure a pulse at CF output pin , I find a distorted pulse and it is constant even in the absence of load.And F1 F2 output also provide the different distorted pulse
I find same frequency pulse on CF and F1 F2 . How can I calculate energy using ADE7757
this equation calculated the f1 f2 freq with a given set of inputs on v and I. Note you will need to calibrate using a v and I of a known value.
this table shows the ratio of cf to f1 f2 freq.
cf will be 16,32,64,128 or 2048 time faster that the f1 f2 based on the table and scf s0 and s1

substitute your values on pg 3 to start. pick whatever imp/kwh you want or just use the
Meter constant = 1600 imp/kWh that is defined in the doc.
