Dear, I am developing a energy meter and I am having some problem to understand the ADE7953 **AWATT **and **AENERGY **registers. I can calibrate easily AWATT, but how this register is mathematically related with **AENERGY**? How AENERGY register depends of **CRYSTAL FREQUENCY **and AWATT?

In my case I have a load of 100 W (100 V and 1 A).

I calibrated** VRMS for 10000, IRMSA for 1000 and AWATT for 10000, but AENERGY is accumulating 1541160 pulses** in an hour. I think it must accumulate the same value of AWATT in an hour (I get the AENERGY value every second and accumulate it in RAM).

Why is it happening? I missed something?

Dear Analog Devices people, to avoid lots of multiplication operations in my meter, I calibrated the VRMS for 10000, IARMS for 1000 and AENERGY for reach 0.1 wh/imp or 10 imp/wh in the kWh led.

In this case, to get the Watt information from AWATT, I need to mutiply this value for a CONSTANT K. My meter is working correctly, but is very important to me to know the mathematical relation between AWATT and AENERGY.

I tried some diferent values of crystal frequency and the AENERGY value changes, but AWATT value is still the same.

Can someone send me this information or point where is it documented?
