Numerical integration

[kajo97]

Hi, I am stuck with a problem. I would like to integrate numerical a Ui signal to calculate magnetic induction B. The problem is that I dont know how to find out the integration constant. Because the shape of the integrated signal is correct, but the amplitude is  not. 

Thank you in advance

So there is a problem with your VI and your data, but all we get to help you is an image of the block diagram?

Usually dt is sample rate, as you already have calculated.

When you say "not correct": can you determine a ratio between expected and calculated result?

(Part of the problem might be the use of ExpressVIs and DDT wires. The FOR loop isn't needed at all and there exists an Inverse function…)
