wired electricity sensing from a new assembled emon tx
Submitted by Guest on Thu, 15/03/2012 - 15:31I just get a emon tx 2.2 kits, and assembled them today.
I have loaded the emonTx_123.ino, it works. But what is wired to me, is even there is no CT sensor on the three CT1, the output can still shown out in Serial. and sometimes, I only hooked the CT sensor to the CT1 port, it showed 0, while the other port can get something.
What went wrong to me

That seems fine, it will still attempt to measure from an empty port if the CT channels are enabled in software.

So how do I know which value is the good value?

You should disable reading from the CT channels that you don't require.
