Very strange problem with the EE range meassurement :(

by pharizna on Sat, 23/02/2013 - 18:34

I've just received and "installed" the Fluksometer. Really, I'm trying to test it first meassuring the EE consumption of one individual appliance.

I'm using a 50A clamp and 230V in my sensor nº1...

The problem is that, you can see in the file attached, Fluksometer indication is 11 W ... but the real data (Current Cost's EnviR meassure) is really about 145 W .

The Fluksometer read ... it live... and the voltage output from the clamp is 8.3 mV.

Any idea to explain this strange behaviour?

Best regards and thank you in advance

Pedro

How did you try to measure the appliance? Be sure to put the clamp just around the live wire, not both, live and return...

Thanks Gebhardm for your help.

Teorically, I put the clamp just around the live wire.. as previously I did with the CurrentCost clamp :)

Anyway, I take off the clamp ... and putted in the return wire... and now it's working properly :)

Best regards

Could be that the clamp wasn't fully closed the first time.

Probably because now it's working fine as you can see in our spanish review :)
