How can I zero out offset voltage at the start of the program?

I have a simple program that reads a voltage input and outputs the results to a file. The voltage has an offset (which changes from test to test), and I am interested in zeroing out this value at the start of acquisition. I could use an example of how to do this. Thanks.

Try this simple method...
Right click on the icon which represents the offset voltage. Select create: Invoke Node.
Use the finger pointer and click on the "Method" of the newly created Invoke Node. Choose "Reinit To Dflt"
Place this Invoke Node at the beginning of your vi by running the Error In through it.
And "voila"... everytime you run your vi, it will reinitialize it to the default value... which can be zero.
You can use the same trick to re-initialize values if a certain condition is met within your vi.

  • How can i pull out data from a spreadsheet only from the current month?

    Data is constantly being fed into a spreadsheet using a VI, this data comprises of such things as month, year, weights, std dev, etc.  I want to do some data manipulation on the current months data while the VI is running, how can I pull out only the data relating to the current month?  Each input into the spreadsheet stores the values for that run on one row, and there are perhaps 150 runs each month
    Any thoughts are greatefully received
    Thanks

  • How can I zero out the memory on my macbook air?

    I have an 11 inch mid 2011 macbook air and cannot figure out how to erase the memory so that none of the data is recoverable. I booted from the recovery HD but when I went to the erase section of the menu, the security options button and the zero out empty space option were both greyed out. How can I clean off my Mac?

    You can't, and don't need to, zero an SSD in Disk Utility. Once you've erased it the data is unrecoverable.

  • HT1311 How can I zero out my appstore credit?

    Hallo gurus
    I have a remaining 0.24 euros in my balance. Because of this spare change residual I cannot switch appstore nation. There seems no apps that I can buy with such a small credit in my account. How can I get rid of it?
    thanks in advance

    If you can't spend it then you can try contacting iTunes support and ask them if they can remove the balance so that you can change countries : http://www.apple.com/support/itunes/contact/- click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption

  • How can I print out a Panorama image to fill up the paper

    I have a HP Officejet Pro 8500A printer and have taken a picture in the Panorama setting and want to print it out on a 4x6 but have it fill up the complete 4x6 paper, not just the center part of the paper. Can this be done without losing quality and if so, how?? I am running Windows Ultimate 64 bit

    Hi if the picture is high res enough you can fill up the page without to much quality loss, should be a question of playing with the settings, you are however goin to lose a part of the picture or stretching the image. A better option might be purchasing some HP panorama paper.

  • How can i find out serial no of torch 9800 without the phone.

    How do I find out serial no of my torch 9800 without the physical phone ( is it in the packaging to the brand new phone?) so that I can report it being stolen and alert anyone buying a stolen hanset in 2nd hand Market. Who should I report it having been stolen after repotted it having been stolen to the police.

    Your cell carrier would have a record of it. They might even blacklist the phone so nobody else can use it.
    Give them a call to see what they will do for you.

  • How can I find out what is in each portion of the capacity bar?

    Does anyone know?

    You can not access the backup directly.
    Did you restore your replacement from this backup?
    If so then you already have everything in the backup on your device.
    If not, you can wipe the device and restore from this backup:
    Settings > General > Reset > Erase All Content & Settings
    What is it you are worried about losing that isn't already on your current device?
