Hi Everybody,
I'am doing a project on ade7754.
I gave a ac signal of 12VAC to the voltage input(Phase A) of the ade7754 evaluation board.
I read the register corresponding to A phase voltage.(RMS)...and i got some value...(eval board is not caliberated...So values are irrelevent)...Then i removed the voltage(12VAC) from the input terminals....
Now i read the same register..But it is giving a erraneous value(It must be zero)...We checked the voltage through the multimeter ...it was "0".
So is the problem due to
1) Reference voltage? or
2)Just because of calibration(WE have not done any calibration)
We have not done the calibration as we atre waiting for our test kit.
THanking you
