Very large values from accelerome​ter

Hello,
I did a small impact test in the lab, and recorded the acceleration. But I got very large peak numbers, like 300g, which is unreasonable. My vi has been checked by many people, seems like no problem. Does anyone have the idea why I got such big numbers?
Thanks.

It would be helpful if you describe your hardware, DAQ , (signal-conditioner with setting) , sensor
and please post a link to the spec-sheet of the sensor and (if you have) the individual sensitivity (cal) value(s) of your sensor. (in metric if possible )
Now read the input voltage at a high sample rate (you can use one of the example vi's ) . If you have a pulse in the diagram hit edit-make current values default, save as a new vi and post that vi.

  • Can't open very large JPEGs from PSE 13 on other computers

    I've produced JPEGs in the 40-300 MB range in PSE 13 (Windows 8.1).  However, I can't open them on other computers operating with Windows Vista or Windows 7.  I get an error message to the effect that "Windows Photo Gallery can't open - file format not supported, or you don't have the latest updates to Photo Gallery".  I do have the latest updates, so that's not the issue.  The photos will open through PSE 11 on one of the other computers, but that won't help if I give the photos to someone who doesn't have PSE on their computer.  Any ideas? 

    Does this help?

  • Rendering large values on the LinearAxis(Y)

    Hi all,
    In our app, theres a problem when we send out very large value as the max value for Y axis for a ColumnChart.
    LinearAxis is being used for y axis and when page loads, timeout occurs  and nothing is dsiplayed
    (some error in AxisRenderer)
    So the question is
    1. Can i get around this by writing a custom label function. If so How (i have seen some common examples..but thats
    for a limited and where max is small)
    2. Is there any bug related to this
    Please advice
    Thanks
    sbelur

    Hi Mike,
    More info on what your chart is reporting an what it it reading from its source chart is probably what it will take to give you an actual solution. Cmd-shift-4 will turn your cusor into a crosshairs you can drag a selection that is saved to your desktop as a screenshot.
    But here is this anyway.
    So this is my step by step. Sorry I wasn't clearer. I have a table where I am reading the left hand column for my Y axis. 4 other columns for a bar graph.
    In the reference sheet I select the table and add a header column before my first (the one being used for Y values). On my Mac the change shows up right away in my graph. This worked for me also in iOS.
    More directly, on my Mac, I can select the chart, double tap on the y axis label and edit directly. I can also edit the legend directly like this.
    My X axis is simple numbers- it is reporting the frequency a entry shows up. The main control I have here is how many steps to show from 0 to 24 (the largest result), it must be a number as that is all it gets from my source table.

  • C5280 using Win 7 suddenly will print ONLY large print from documents & internet

    My C5280 using Windows 7 on my PC suddenly prints ONLY very large print from documents or internet. Not aware of any changes made to the to the computer or printer before it started.  Have downloaded some updates since it started this, but made on difference.
    This question was solved.

    Try to print a test page or make a copy of a document and see if you get the same results. If you do not get same results, uninstall and re-install software and drivers.

  • Profile Performanc​e and Memory shows very large 'VI Time' value

    When I run the Profile Performance and Memory tool on my project, I get very large numbers for VI Time (and Sub VIs Time and Total Time) for some VIs.  For example 1844674407370752.5.  I have selected only 'Timing statistics' and 'Timing details'.  Sometimes the numbers start with reasonable values, then when updating the display with the snapshot button they might get large and stay large.  Other VI Times remain reasonable.
    LabVIEW 2011 Version 11.0 (32-bit).  Windows 7.
    What gives?

    les,
    the number indicates some kind of overroll.... so, do you have a vi where this happens all the time? Can you share this with us?
    thanks,

  • Help with getting values from request. Very Strange!!

    Hello,
    My very strange problem is the following.
    I have created three dynamic list boxes. When the user select
    the first list box, the second becomes populated with stuff
    from a database. The third becomes populated when the second
    is selected. Now, I have used hidden values in order for
    me to get the selected value from the first listbox. The
    following code is my first listbox:
    <SELECT NAME="resources" onChange="document.hiddenform.hiddenObject.value = this.option [this.selectedIndex].value; document.hiddenform.submit();">
    <OPTION VALUE =""> Resource</OPTION>
    <OPTION VALUE ="soil"> Soil </OPTION>
    <OPTION VALUE ="water"> Water </OPTION>
    <OPTION VALUE ="air"> Air </OPTION>
    <OPTION VALUE ="plants"> Plants </OPTION>
    <OPTION VALUE ="animals"> Animals </OPTION>
    </SELECT>
    I use the getRequest method to get the value of hiddenObject.
    At this time I am able to get the value of hiddenObject to populate
    the second list box.
    But, when the user selects an item from the second list box
    and the second form is also submitted,
    I lose the value of hiddenObject. Why is this??
    The code to populate my second listbox is the following:
    <SELECT NAME ="res_categories" onChange="document.hiddenform2.hiddenObject2.value = this.options[this.selectedIndex].value; document.hiddenform2.submit(); ">
    <OPTION VALUE ="" SELECTED> Category</OPTION>
    Here I access a result set to populate the list box.
    Please help!!

    Form parameters are request-scoped, hence the request.getParameter("hiddenObject"); call after the submission of the second form returns a null value because the hiddenObject parameter does not exist within the second request.
    A solution would be to add a hiddenObject field to your second form and alter the onChange event for res_categories to read
    document.hiddenform2.hiddenObject.value=document.1stvisibleformname.resources.option[document.1stvisibleformname.resources.selectedIndex].value;
    document.hiddenform2.hiddenObject2.value = this.options[this.selectedIndex].value;
    document.hiddenform2.submit();You will then come across a similar problem with your third drop-down if indeed you need to resubmit the form...
    A far better approach would be to create a session scoped bean, and a servlet to handle these requests. Then when the servlet is called, it would set the value of the bean property, thus making it available for this request, and all subsequent requests within the current session. This approach would eliminate the need for the clunky javascript, making your application far more stable.

  • To extract null Values from the source in Infopackage selections - Very Urg

    Hi All,
    I need to pull the data which has null values from source. I tried to write routine by giving l_t_range-low = '' , space. nothing is working.
    Please guide me with sample code.
    Very Urgent.
    Regards
    Mano

    Hi Mario.
    Assuming that you want to avoid uploading of records having
    zero for a keyfigure:
    Create a startroutine for transfer rules and add this coding:
    DELETE DATAPAK WHERE VALUE = '0'.
    OR
    LOOP AT DATAPAK.
    IF DATAPAK-VALUE = 0..
    DELETE DATAPAK.
    ENDIF.
    ENDLOOP.
    'VALUE' represents the fieldname in transferstructure
    Please let me know if i misundersttod the issue.

  • How do I stop itunes from downloading a very large apps that I downloaded direct to my iphone?

    To get around my 5GB limit for internet service, I download a very large (350MB) dictionary app directly to my iphone using a wireless website run by a merchant in town. Now every time I run itunes, it wants to download the app. Is there any way I can stop itunes from attempting the download?

    Some types of issues, such as that one, can't be resolved by the volunteer support here. If I think a request can be answered in the boards but was posted in the wrong part of them, I'll just ignore the fact it's in the wrong place.

  • --single very large photo montage TIF from 15 individual TIFs--

    This is novice question, sorry if posted in wrong area...
    Any easy way to take 15 TIF 300ppi horizontal images from (mixed) 6mp, 8mp, & 10mp cameras & place them in 3 columns 5 rows deep with 1" space between all images sized to 8"x12" each to make a single very large TIF of about 4'x5' with 2" border?  What size TIF is this likely to be?
    This crude graphic approximates what I want single giant TIF to look like:

    One easy way to do it is to make a new Ps document that is the final size and resolution you need, then set up a grid of guides where you need them and drag the images into the new document, sizing each layered image to its predetermined space in the grid. The Free Transform tool will snap to the guides and your sizing will be very fast and accurate. You should be able to slap this together in half an hour or so.

  • Can I move my very large iPhoto app and photos from main HD to a larger secondary HD via drag and drop?

    Can I move my very large iPhoto app and photos from main HD to a larger secondary HD via drag and drop?

    Welcome to the Apple Discussions.
    1. Quit iPhoto
    2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
    3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
    4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
    Regards
    TD

  • HT5260 Hi, my name is Gerard and my iphoto library is getting very large I would like to know if I can store all or most of my photos in a external hard drive and access them from Aperture?

    Hi, my name is Gerard and my iphoto library is getting very large I would like to know if I can store all or most of my photos in a external hard drive and access them from Aperture?

    Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
    And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
    And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive
