Problems with a weight curve

[julian14051992]

Hi there, 

for my master thesis, i need to visualize a weight curve. 

I have a Kern PCB 1000-2 connected to my computer via USB and i use the VI as seen in the appendix.

But as you can see, i get very high ups and downs in the curve and i have absolutely no clue why this happens. 

Does someone has an idea?

Thank you! 

Julian

I have a Kern PCB 1000-2 connected to my computer via USB and i use the VI as seen in the appendix.  Attaching the VI would be little effort on your part.  Most of us don't know what a Kern PCB 1000-2 is ...

But as you can see, i get very high ups and downs in the curve and i have absolutely no clue why this happens.  Where, precisely, can we "see" this?

Does someone has an idea?  Yes.  First, attach your LabVIEW Project (compress its folder and attach the .zip file), and some representative data.  Explain what you are trying to do, including what a "weight curve" is.

Thank you!  Glad to (try to) help.

Hi Julian,

several problems:

Initializing the COM port in each iteration of the loop.

No error handling when converting from string to numeric.

Closing the port in each iteration of the loop.
