Re: ADE7878 Evaluation Board - Beginner

Hi David,

 

First of all could you clarify me on how you got the decimal value from the hexadecimal? I am not getting the same decimal value as what you got. Could you tell me which all bits I must convert to decimal for the value and which bit is used as sign bit?

 

I need to reverse my CT connections? Does that mean giving the phase to neutral in the board and vice-versa? I didnt get the part where you said to reverse CT connection.

 

And to calculate the kWh/LSB I need to do the same process as I did for V/LSB and I/LSB?? Apply a known power, read the register value and then find kWh/LSB. Is that all?

 

I saw some posts in the forum where they were asked to do something in LCYCMODE or some other registers. After reading all those I started to loose my marbles. I thought it was just the same was as I found the V/LSB and I/LSB. Please make me understand what I am supposed to do to get real-world values without any errors.
