We are set up in line accumulation mode using the ADE7763 and now monitoring the active energy register, 0x02. We run thru the entire program loop and read the data- it’s a state machine so no interrupts. We then store that value wait a fixed period of time, read again and subtract the two values. At zero we read FFFFF as there is no offset correction. Raw data is viewed as follows:
Actual kW 0x02
The numbers are repeatable- we appear to be missing something fundamental in our understanding?
We have two test configurations:
A low voltage or 120 volt system utilizing light bulbs as a load.
The second system involves monitoring a single phase or a three phase system utilizing a lathe as a load.
