Dear All
I had use this software for a long time.
I am using 2 analog voltage and current sensors that connect to ni usb 6009.
I am measure temperature too with a lm35.
The sin of voltage and current seems correct. Multiply this 2 sin I have the power (watt)
The problem becomes to calculate joule because I integrat but the results are not convincent.
In 60 seg I should have 1000Wx60seg=60000 Joule
I am using a heater with 1000w power. I should have Joule/360000=kWxh and in 1 hr I should have a value near it. But no.
Can somebody see my code and give me a help?
Best

No, because you password protected the VI.
And since we do not have your hardware, it would help if you did a small run and then saved the values as default so that we can analyze the data as well.

Here is the solution
The problem were in the integration (I only have 1 sample, the mean) but multiply this mean by the total number of samples gives the correct number of joules.

Thanks for posting back with your solution.
No offense but your block diagram was a bit messy until I ran the clean-up tool on it. It worked very well in this case. Try it out...
