Saving data of deformation

I have a hard time to control the sampling frequency for the data of deformation when using the DAQmx for strain, which is completely identical to the app to express signal for the strain. For some reason any affecting the control single sample size and rate of the buffer, when set on a continuous sampling, so when I try to write data to a spread sheet excell freaks out because I am getting 1000 samples per second by default?

Hello Newbman,

Please use the forums of NOR.  DAQ hardware do you use and how often you want a taste?  Some DAQ hardware, especially with measures of constraint, have an authorized minimum sampling rate.  There is a solution that allows to taste a higher and average rates and points to make it appear as if you have been acquired at a lower sampling rate.  This knowledge base provides an example for the implementation of the workaround.  Although the article mentions the 9237, the principle is always the same for any card.  The first entry is the actual rate at which the map will be sampling to (1 kHz should usually suffice, but depends on the actual card you are using), and the second entry is the rate at which you want to taste.  Try this out and let me know if you have any questions.

Kind regards

    Do you still have the MBP? If so you can manually copy and paste the files you need.

    If you do not have the pro more, you need to buy a USB key and plug it into the MBA... use it as a target. Once you have a system file of the previous laptop again, you have to manually choose what to copy across.

  • First fall of 12 elements, all saved data lost on a new project.

    I was working on a short project that had many video and audio clips. About 3 hours in the first project elements 12 crashed. Now, it will not open the saved data. He simply said "an unknown error has occurred during the opening of the project" Am I GROUND? What should I expect as a regular from Adobe? More importantly, is there a method to recover the project? I am a new user of Adobe Elements and video editing in general.

    Thank you

    Thanks for the update and glad you are moving in your project of first Elements. But...

    Remember... you use first items 12/12.1 on Windows 7 32-bit. Under this condition, first elements 12 or 12.1 runs as an application 32 bit with all the limitations of a 32-bit system, namely maximum supported installed RAM = 4 GB which usually 3.2 to 3.0 GB or less available. This has major implications related to the chance for the greater realization of a project. First 12 elements is a 64-bit application in Windows ONLY when it is run on Windows 7, 8 or 8.1 64-bit. Under this condition, first 12 elements can take advantage of the 64-bit like application resources for these most important project at a greater frequency of success.

    Initially, you said that you were able to complete with success similar to the problem project projects under the existing conditions. At any time you mention no memory low message.

    The difficulty that seems to work for you involves virtual memory not physical memory (RAM). Virtual memory is disk space allocated for purposes of memory.  In view of recent developments, it would seem that the real difficulty for you is to install your first items 12/12.1 on Windows 7 64 bit with about 8 GB installed RAM. I'll go in a further analysis of virtual and physical memory and the/3 GB switch if necessary.

    Nice that you found a way forward in your projects (this is fine), please review and consider the foregoing.

  • Problem of saving data on the form

    Hello

    In my ranks on dataform that I try to save the data for a member and it dosent record. There are three levels for the Member

    A-> level 2
    B > level 1
    C > Level0

    I chose A on the form IDescendants, and if I save data on members C it common record. However when I select only C in the selection of members on dataform data is saved.

    The only thing that comes to mind is that Member C is implicit sharing member (as a member of level 0) and A, B and C all three stored property outline.

    Should I choose member B like never share and select Idescendants would be saved data?

    Please help its urgent!

    Thank you in advance

    Then, it is almost certainly a problem of implicit sharing.

  • Saving data to files

    Hello

    I have to save some data in some files.

    The files are selected by the user using a dialog box. However, when the dialog box appears, it is unclear when the file is saved. Is it possible for the user to perform ideally what file it saves? In my program, the user has the option to save / add data to different files separately. Therefore, it becomes very confusing to remember the order in which appear the dialog boxes. Please suggest a solution to this.

    Also, can you please advice how to tie the timestamps for the recorded data?

    Thank you

    P.S. all the data is saved in a cycle in the loop.

    Dheeraj salvation,

    I understand that during the recording of the user will have to choose two files? To save one and the other to add data?
    If this is the case, you can tell the user which files that they save to the title of the dialog box (the file dialog box has a property named "Speedy" in which you can plug a name/text customized for your dialog window).

  • Saving data in the fields

    I created a static PDF file in ES LCD and set compatibility with Adobe 7.0 and later. When opened in Adobe Pro 7.0 to another computer and saved in a new file with the information entered in the fields of data, when reopened after save some fields erased the provision of information in them. I had security on the document, but have tried without security and the same problem still happens.

  • Saving data of damaged water Macbook Pro

    So, yesterday, a little water was poured on my macbook pro. He thought first of all, it was just a dribble on the outside, (computer had been sitting firm and on the side in my backpack at the time) don't think all obtained through the keyboard... wiped it and everything worked fine. Of course in the later site I must have just turned it off, but was late, put in my backpack and went about my day. When I tried subsequently, the trackpad was goofy. I rebooted and it was fine. Later in the evening the trackpad was once again. I plugged in a wireless mouse (I needed to print something) and it worked fine, but I was nervous that there was more damage than I thought, so I stopped and left to dry overnight. This morning I tried and there are specific problems... it's just jumping around, switching windows, open applications on its own. Not good!! I closed it and put in a request to my COMPUTER technician that certainly will not respond me everyday. :-( It is currently open with a fan blowing on it.

    Right now, my biggest concern is not lose my data. I have not backed up my computer in some time, irony of fate which was my plan this weekend because I'm in the middle of buying a new macbook. What is the probability of losing my data or get this computer again? I'm so angry at myself for not thinking this through as soon as possible. Other than leaving power off and waiting for news of THIS, anything else can / should I do?

    Thank you!

  • Saving data using Write to PDM

    I am looking for the following final result
    -The first column shows the time
    -The second column displays measurement signal No. 1
    -The third column displays measurement signal No. 2
    Fourth column displays measurement signal nr 3

    Hi all

    Inside of my VI (I'm the machine with LIBRARY CALL FUNCTION. data acquisition after that I table of Index for trying to channel and after that I use "fractional number string" so I can "Concatenate" string and write to the file) I save my data in. TXT file. The problem is that the recorded data are in form:

    -0,021362
    -0,022278

    but I need:

    -0.021362
    -0.022278

    So is there any parameter to define the record of data with point and not the comma?

    You do not have context-sensitive help on? Do that and read the help for the function of fractional channel number. Read what all the entries are and what they do.

  • Reading and saving data of two serial ports

    Hi, I googled similar questions in the forum, but I don't have an answer for my problem so I'm posting it here.

    I would read and record data of two balances throgh serial ports. I have a drop down menu in VI, I can choose the availabe ports on my pc. But it is still only one that works. So I only get one data scales them.

    I usually get to choose 6 ports, but only one of them works. So I'm wondering if this is something that has to do with my pc or the VI?

    I've attached a screenshot of my VI.

  • saving data to file or xls

    I log every 0.5 seconds in a txt file. When I need to store more values that I have in this VI structure will be very little claire. Is there a better way for the logging of data?

    Yes.  The 'table in spreadsheet string' function is your friend.  It is in the palette 'strings '.

    You have a lot of unnecessary manipulations in your code.  You don't need to go from a 1 d array (you resized unnecessarily to a 1 d table... why?) to a cluster that unbundle you then, in order to get your data.  You can simply use the table functions.

    In addition, this case structure you - one that contains the "select" functions - is simply ridiculous.

    This

    Is exactly the same as it

    He had a few other things in there also has no sense.  I have tidied up a bit of your code, eliminated most of your useless operations, etc.  Take a look.
