Signal Express to collect wall power

I have a power strip that is instramented for current collection via a NI9227 and an NI9225 to collect the 120v provided from the power strip.

My problem is I can not figure out how to correctly phase lock the I and V in order to calculate W.

I've attempted a project with RMS, but was unsuccesful 🙂


Anyone done this and or can provide some insite?

Thanks, 

Matt

Thanks! By taking the RMS values, I was able to derive my power.
