Hello, ADE Supports !
Firstly, Merry Christmas and Happy New Year !
And Thank you for the supports from the past years.....
It's greatly appreciated !!!
This will be my first discussion in this year.
So, I have designed board both for ADE7953 and ADE7816.
In the past, when I'm in the middle of making it,
honestly, I only follow several steps which I think is needed to make the chip is working.
In case of the ADE7953, this is what I did :
- Making the breakout board/minimum system
- Set the settings needed for UART communication
- Test to read specific register == SUCCEED
- Calibrate or more accurately, I directly search for the V Constant and I Constant
without any additional steps like using The Line Cycle Accumulation, Phase/Offset/Gain calibration,
since at that time, I only concern to the Demo dealine which is super-close !
In the end, with the steps above I manage to show the Vrms and Irms current value, and It will change as I change the load.
With that I survive the Demo stage.
As the demands want more features, such as more channel. Therefore I moved to use the ADE7816.
This time I want to do some more accurate reading.
The problem is there are no accurate meter or reference meter I could use for calibrating.
So, I wonder is there any alternative ways to calibrate the ADE7816 without accurate source/reference meter ?
At least I got "better but not so accurate" reading.
I'll use accurate source eventually, but I think It will takes time, while I have to catch the deadline
for my second stage of the Demo.
Any suggestion will be appreciated.
