offset error null

Hello. I try to take a data of torque on the shaft with the strain measurment (half bridge with 2 meters on 45 degree system). Every time when turn on data zero offset starts at 0 and then move to 80 Nm. The problem is that jump. I don't have any load to have that jump and I prestressed State. I use filtering (low-pass 1 Hz) for noise static System. Can someone help me with which jump problem. Thank you.

You use a filter low low pass of Veery... so start acquisition, wait for the filter to move, use DC estinate vi on a long datablock and subtract this value from the following data (after filtering, or wait one more time the filter set...)

You'll run out of memory

  • Backup problem: iMacG5.sparsebundle could not be accessed error null


    I have an iMac G5, 27 "; Processor - 3.4 GHz Intel Core 17; Memory - 4 GB 1333 MHz DDR3; Software - OS X 10.9.5 (13F1808)

    Since yesterday, it was not able to Time Machine backup.

    The initial error was "iMac that G5.sparsebundle could not be found (error-1).

    I found a few tips here and there followed:-unplug TC; go to network/SystemPreferences, renew the DHCP lease

    Still did not work.

    Is passed to the next stage of advice:-open the TM preferences panel, remove the TC list of backup destinations, add in

    Still did not work.

    Error message has now changed to "iMac that G5.sparsebundle could not be found (error (null)).

    Is this a defective Time Capsule?  (This is the conclusion, in other similar post, I found that my error message ('null') is different from that of this post).

  • Time machine could not complete the backup of... The backup disk image could not be found (error (null))

    Running OS 10.11.3 on my early 2011 Macbook Pro 2.7 GHz Intel Core i7 with 4 GB 1333 MHz DDR3, use Time Machine to back up to my Airport 802.11ac purchased 16/09/2014:

    Backup failed: Time Machine could not complete the backup of... Airport Time Capsule.   The backup disk image ' / Volume/Data/MacBookPro.sparsebundle ' could not be found (error (null)).   Last successful backup: yesterday at 12:17

    I can see the airport and the data file in my network.

    I immediately did a full time Machine backup on a USB key and it disconnected from my system.

    I unplugged the airport, let it rest for a minute and returned the power plug, let it settle for a green light.  I'm restarting Time Machine backup to the airport.

    I need to replace the airport?  The appliance starts to fail?  Or, it is more likely is a problem with winter static electricity that has damaged the image and reconstruction will fix all this.  Reconstruction will take about four hours with no guarantee that it will work.

  • Set up for the signature of 10 BlackBerry applications (error: null)


    I am recording my WebWorks for BB10 debugging application token so I can try an application on a device (Playbook). I followed the exact steps that lie in this documentation:

    When I run the command:

    All I get is the following:

    Error: null

    He does all the work and failed in the last step which is supposed to create the author.p12 file. The ' error: null "really doesn't tell me much about what is the problem. The people who work on it really should display error messages that are more appropriate.

    So my question is: Y at - it a newspaper or something that I can work on this error? Does anyone have an idea what is a failure because I did several times and each time that I make sure that I don't the steps correctly, so I do know not what is happening here.

    I would really appreciate help with this.

    I need to synchronize alertdefinitions based on XML files please help me around this error.

    Thank you very much.


    Trying some updates for automatic alert via the script API definition, I met this problem as well. No matter what I did, it seemed that this class cast exception would be thrown. I downloaded the Github source HQAPI and started searching. I found that the error was in the call to the XmlUtils.deserialize method, which has invoked a JAXBContext to select the class of the object to return, after analysis of the XML. The code that calls the method waits get an object that can be cast to the type AlertDefinitionsResponse, but he returned to an object that must be cast to type AlertDefinitionResponse.

    After a bit of investigation, I realized that JAXB is the context of the node root XML data. Because the root node is AlertDefinitionResponse, he always returned an object of this type, instead of the expected AlertDefinitionsResponse type. Currently, the only way I found to get around this problem is to change the node root to AlertDefinitionsResponse. So, sync-able XML would look like the following, based on XML of the original poster.



    I raise a question on the Github repository so that officials are aware of this problem.

    EDIT: The problem has been discussed here

  • Internal generator is used for construction - construction of error (null)

    Hi all

    First things first... It's the IDE, I use:

    QNX Momentics IDE for native BlackBerry SDK for Tablet OS

    Version: 2.0.0

    Build id: 201202171813

    I imported an assembly from another project file, I worked on (extension .s). I started having a linker error when I have a function in the referenced file. The project picked up the declaration of the function in the header file (.h), but not the definition in (.s) file.

    The first thing I found was an article on how the IDE requires le.s extension is case sensitive. I changed the extension of the file in uppercase. In addition, I also did the following to be recognized and treated as the assembly files lowercase extensions:

    Project-> properties-> C / C ++ general-> file-> new Types

    Model = *.s

    Type = Assembly Source file

    After noticing that there is no compilation error, but the linker could not yet find the function that I checked the file object (.o), and of course no file has been generated.

    I then tried to build just the assembly file (right click-> selected Build queue (s)).

    This is what I get in the Console:

    Reconstruction or the files selected

    Internal generator is used to build *.

    Build error


    Addition of preprocessor #error throws any error. Adding indefinite #define tags around the code does triggers not any kind of syntax highlighting in the editor, as it does in c/cpp/h file.

    Here are my parameters of QCC assembler (project-> properties-> C/C++ build-> settings-> assembler CQS):


    Options: - V4.4.2, gcc_ntoarmv7le_cpp-w1 - c-DUSING_GL11 = 1 - g

    In case anyone asks, I can't post the source for this (contract).

    Could someone suggest to get this working? Someone at - it had a similar problem and resolved it?

    See you soon,.


    In fact, I think it's this bug:

    I noticed that the .cpp file has a "set" on the icon of the file. It looks like a key or a key. There seems to be a bug in Momentics/Eclipse, which causes the compiler to fall with an unspecified error (zero). I've renamed le.s file to. S and also renamed the .cpp file. I'm going to hazard a guess that by renaming the files was the cause.

    The solution for this:

    • Duplicate the file in another location and delete the file of the project (right click-> 'Delete').
    • Copy the file in the project directory where it used to be in the Finder (or Windows Explorer in Windows).
    • Refresh the project (right click-> "Refresh").
  • OES ID profile error: Null pointer Exception

    I have a new installation of IOM and OES 11 GR 2 on the same weblogic Domain.

    I can see the IOM default administrator roles in the OES console but when I try to create a new profile of IDS to pull in the roles of LDAP I get a null pointer error. The connection to the server OID is successful, but by clicking on the button create gives the question.

    Also, I discovered this null pointer exception is thrown to the right when I click on create to create the profile of the IDS and so perhaps that's why the operation is a failure.

    All entries on the question would be very appreciated.

    Kind regards

  • Error when packaing Swing/JavaFX apps


    On Mac OS X Lion, using Java SE 7 update 6 and 7.2 Netbeans I try to create a native bundle for a combined swing / JavaFX app.

    A test, I use the sample application JavaFX 2.2, SwingInterop

  • Problem error null object reference

    Hello, I'm having a problem with a class (_gameModel), to instantiate in another class (_gameController), and when I try to reference the _gameModel class in the class of _gameController, I get an error of object reference anywhere, even if I know that the class is instantiated at the top of the page of class _gameController.  I thought that if it was instantiated in the class, then I don't have this problem but I am. Someone knows what's the problem? Thank you

    I don't see anything being instantiated compared to what you said, so I can't say if it of a problem or not.

    You showed only a part of the error message or is there more information in it?  Display the full error message if it is not all that.

    Based on this function involving 'EnterFrame' in the name, my suspiscions down wondering if you spread this error once the object has been deleted on a previous passage through the function.  How to watch the traces of this first line of the function?  Does come with a null value when the error occurs, but looks OK before that?

Maybe you are looking for
