Got the new one hooked up for a little testing. It seems to be working.
I had to Zero out the history, so it would start fresh on the new one. (on right).
I'm not sure if these will keep working on the same circuit, but so far.. Okay..
I think the display updating might be a little slower than normal.. But not bad..
So far, the $20 TED is working as well as the $140 TED..
