Years ago I installed a TED-1000 (now obsolete) system from
http://www.theenergydetective.com/. Their software is terrible but
the system works. This system uses two current transformers and a
single voltage measurement system that all go inside your circuit
breaker box. I don't recall the

I assume you mean when the DVM is disconnected - otherwise you
wouldn't spend more than $20 on a meter! But I said that in my

Actually, I meant
You can find the data sheet at http://www.ti.com/product/lm331.
Their idea of precision is not in the same league as a Volt Nut or Time
Nut (Worst case values):
Non-linearity: 0.14%
Temperature Stability: 50 ppm/C
Supply Sensitivity: 0.1 %/V
Many years ago I used one of these for a project
