Help with Creating Load Cell VI

[Koolbro360]

Im linking remotely into the another computer from my own. Im sure I can save the VI and send it to my self thru email, but I took a screenshot of it just in case you asked and I can send the code later.

Hi Koolbro,

a picture taken from a real computer screen is useless. Even a real "screenshot" is useless - we still cannot debug images using LabVIEW.

And with all those ExpressVIs (hiding all the details!) it is even more useless!

You didn't even care to use AutoCleanup before posting an image…

When you are asked for code, then you should attach code!

First off, that was a screenshot from my VI that I worked on last night. Second, I received ZERO help regardless of posting the VI or not. I know its a simple matter, but my project has to be ready by tomorrow and if I cant even get a simple amount of info there is no point in me asking. Here's the VI. Whether I receive help at this point doesn't matter anymore. The only issue I have left is the calibration factor. 

Thanks for your generosity.

As said we cannot debug pictures with LabVIEW, so they are mostly useless…

You did not post any VI before. And usually we don't solve homeworks for free, there has to be some engagement from your side!

Building a "zeroing" feature is quite simple in LabVIEW once you did the basic training. It just involves a shift register and a select node (or case structure)… (This feature is also known as "tare", and it is quite often asked for in this forum. Did you even try to search the forum for similar questions?)

We are not responsible for your deadlines and work time you put into this project. You were asked to provide a VI some days ago, but decided just to attach an image later…

I guess this is that "1" constant you use to multiply the data with…

Apart from that there are a lot more issues to your code, like the still missing zeroing feature! That "Statistics" ExpressVI set to "first value" does not what you apparently expect it to do…

Your statement sounds desperate, which is not "Kool".

I totally agree with Gerd.  A screenshot or a picture does not encapsulate or show all the data that is within the code.  Furthermore, the other case is hidden, so there is a lot of code out of view. 

How would you offer advice to anyone if you do not have all the information / facts?

[Koolbro360]

The person who previously started this thread is not a colleague of mine. I have no clue who that is. They are just doing a similar project nothing more. As for the calibration, my team and I had decided that we would just take the data and then apply the calibration afterwards in an attempt to make the code easier to manage. So far it takes the data fine from a simulated stand point. We are testing it in the lab today to be sure. For the zeroing output, that is where the "tare" function should come out. That value would then be written down to be deducted from the actual value that is read from the load cell.

I looked for training videos, but it says I need active software which I don't possess. Also I looked at the thread involving the tare function and got some useful information which I believe might help if we do decide to create a zeroing function in the VI code. However, if the values we are measuring come out correctly we would only need the data and then we can just apply the zeroing function afterwards.
