How I can resolve the offset readings

I am applying a triangular vawe signal varying between -1 V and 1 V using E serie DAQ board. When I am reading the output signal it varies between apr. -0.4 and 0.4 V. I suppose I have an offset reading problem. I would like to know if the only way to resolve this problem is calibration the board or if there is any other think I can do?
Thanks
Pier

Does this occur when testing the analog input channels within Measurement and Automation Explorer ?
You can perform a self-calibration for your board and see if that removes a problem. If not, then I would recommend testing your board by doing the following:
Try connecting the +5V pin on your E series board to ACH0, and AIGND to ACH8, and then run the analog input test panel and read ai0 in differential mode. If it reads 5 V, then your board is functioning correctly.

  • When I switch libraries I lose the majority of the material in my main library and can only restore it by repairing the database. Can anyone tell me why this is happening and how I can resolve the problem? Thanks

    When I switch libraries I "lose" the majority of the material in my main library (or at least I can't see it) and can only restore it by repairing the database. Can anyone tell me why this is happening and how I can resolve the problem? Thanks

    I seem to have found a way around it. Rather than switching libraries by going into files/switch libraries I used Aperture Preferences to change them. I've done it a couple of times and it appears to work OK.
    That is an interesting finding. It suggests, that your "Preferences" file "com.apple.Aperture.plist" may have been corrupted and you fixed it this way. Can you now switch between libraries the usual way? If not, I'd try to remove the "preferences" file from the user library to the Desktop and relaunch Aperture.

  • HT4623 i am unable to charge my iphone 3 when I connect to my iMac 10.6.8. Cable is working appropriately. Please let me know how I can resolve the issue?

    Unable to charge Iphone 3. I have tried charging through 3 ways -- wall mount, imac 10.6.8, as well as itunes installed on windows. While wall mount and imac charging stopped few months back, windows was still in a position to charge. today onwards, nothing is working

    That message covers several things. Most often it is a cable problem, switching to another cable (Apple certified) often fixes it.
    Second it can be security software on your computer interfering, temporarily disable all of them and try again.
    There is a third jailbreak related issue, you could be attempting to contact a site other than Apple. Try it on a different computer where a jailbroken device has never been used. The final jailbreak issue normally affects certain models of the 3Gs but possible can affect a 3G. Altering the baseband chip for your unofficial unlock my have damaged it.

  • I get an error message when trying to sign into the support community with another Apple id. On the pick a username screen I get "an account utilizing this address already exists...." despite trying a few usernames. Anyone know how I can resolve this?

    I get an error message when trying to sign into the support community with another Apple id. On the <pick a username> screen I get "an account utilizing this address already exists.Only one account per email address is allowed on the Apple Support Communities" despite trying a few usernames. Anyone know how I can resolve this?

    This problem has been driving me demented. The instructions that Ivan gives have partially worked for me. By following his link
    "How to find out if you have multiple Apple IDs" I was able to identify that yes I did have two apple accounts using the same e mail address. One was very old that I used to use for the forum boards and one is my much more recent ID that I use for everything these days. So I changed the e mail address for the old account which is associated with these discussion boards and that's the account that I am now posting this from. However even though the two accounts now have different e mail addresses when I try to log onto the boards with my more recent main apple ID I still get all the same errors as described at the start of this thread by rodgers_j. And of course that's the one I want to use so that I only have one itunes account for everything.
    So if anyone has any more hints I'd be very grateful.

  • "SOME" devices can resolve the ALIAS (CNAME record) for a device, but not the REAL name (A record) - Why? How do I fix this?

    I'm running the DNS server role on Windows Server 2012 R2 on a physical machine on my home network.
    My AD is configured with a non-registered name - let's say it's "home.acme.ca" and the DNS server is configured to host that zone.  I also configured a 2nd zone in the DNS server called "myinf.acme.ca".  They both run on a physical
    server with an IP of 192.168.1.10
    The DHCP server on my Cable Modem is configured to hand out 192.168.1.10 as the only DNS server to every device on my network.  On my servers (with static IP addresses), 192.168.1.10 is configured as the only DNS server available for them. 
    I took the DNS servers from my Cable Provider and configured a Forwarder on my server to send name resolution requests to them only if my DNS server can not answer the request - basically for any name resolution request that does not end with ".home.acme.ca"
    or ".myinf.acme.ca"
    The "home.acme.ca" zone is populated with 'A' records for all of the physical and virtual servers and PC's on my network.
    The "myfin.acme.ca" zone is populated with 'CNAME' records that point directly to the 'A' record in "home.acme.ca" - for example, I have a serve named s000abc123ww.home.acme.ca with an 'A' record providing an IP address of 192.168.1.20 and
    I created a 'CNAME' (alias) record named 'webserver.myinf.acme.ca' which points to the 'A' record 's000abc123ww.home.acme.ca'
    2 of my 6 machines can resolve the alias but not the real name of the server!
    .10 is the Domain Controller.  All of the other machines (except .98) are members of the home.acme.ca domain.
    I attempted to ping 's000abc123ww.home.acme.ca' AND 'webserver.myinf.acme.ca' on the following 6 computers.  I used the fully qualified name in all cases.
    4 of the below machines are able to resolve BOTH names.  The other 2 can resolve the Alias but not the real name!
    I don't understand how this is possible, but I would like to fix it...!!!  Please help?
    .10 - Server 2012 R2 (Physical) -  Hosts Active Directory and DNS.
    .20 - Server 2012 R2 (Virtual)   -  Runs SQL Server
    .21 - Server 2012 R2 (Virtual)   -  Runs Apache
    .22 - Server 2012 R2 (Virtual)  -   Runs Apache.  This is the device I am trying to ping (s000abc123ww)
    .98 - Windows 7 (Physical)
    .99 - Windows 7  (Virtual)
    .21 (which is configured nearly identically to .20 and .22) can resolve and ping the Alias, but not the real name.
    .98 can also resolve and ping the Alias, but not the real name.
    The rest of the machines can resolve and ping both the alias and the real name.
    All of the Virtual Machines are running under Hyper-V on the .10 physical server.
    All the devices are on the same subnet.
    Thank in advance to anyone who can help me understand and correct this problem!

    Hi,
    CNAME resource records are recommended for use in the following scenarios:
    • When a host that is specified in an A resource record in the
    same zone needs to be renamed
    • When a generic name for a well-known server, such as www, must resolve to a group of individual computers (each with individual A resource records) that provide the same
    service, for example, a group of redundant Web servers
    Therefore please try to create your CNNAM record in the same zone and try again.
    The related KB:

    Question # 1 is what do you mean by "inherited"? Is this a case where the computer belonged to someone else? Your user would not be entitled to use a program licensed to someone else.

    If version 4 is an upgrade only, you will have to have the serial number of the 3.5 full version.
    If you can't find it try contacting Apple with your proff of purchase, they may be able to help.

  • How do I resolve the issue Cannot open the file ".indd". Adobe InDesign may not support the file for

    How do I resolve the issue Cannot open the file ".indd". Adobe InDesign may not support the file format, a plug-in that supports the file format may be missing , or the file may be open in another application?

    Shouldn't the CC version be able to open any file created in an older version on InDesign?
    Yes, it ought to.
    If the older file wasn't yours (if someone emailed it to you,or burned it on a disc, or whatever), then I am almost willing to bet you a beverage in the city of your choice that it's not a complete InDesign file. That is, maybe it was zipped and renamed, or the beginning or end of the file was chopped off during download, or something like that. The only reason I'm not actually making the bet is that there is a remote chance that I'd lose, and maybe you're in Adelaide or Khabarovsk or somewhere where the cost of airfare to me would make that bet a very expensive bet for me to to lose. So no latte for you if I'm wrong!
    The script that Jongware posted will tell you what version of InDesign made the file to begin with. Additionally, if someone did something like rename YourFile.PDF to YourFIle.INDD, it'll report that it's Not An InDesign File. Because while SpectrumPCS is kinda right and that message can be generated when attempting to open a CS5 file in CS3 or whatever, it also spits out the same message when you just try to open an Autocad file, or a Windows system file, or a PDF, or any file that InDesign actually cannot open at all.

  • How do I resolve the server error"403"?

    How do I resolve the error message in Ical when I am trying to accept a meeting invitation and get:
    The server responded: “403” to operation CalDAVWriteEntityQueueableOperation?

    First, try the simple fix: back up all data, then delete the calendar account and add it back. If it's an iCloud account, all you have to do is uncheck and recheck the box marked Calendars & Reminders in the iCloud preference pane. Test.
    If there's no change, then you may be trying to access an event in a shared calendar that you declined. The error message should give you a clue as to what it is. If the calendar is on iCloud, you can bring up the Calendar on the website and select 
    Show Declined Events
    from the popup menu with the gear icon in the upper right corner of the page. The declined events will appear in gray, and one of them should match what's shown the error message. [Credit for this solution to ASC member Psi.]
    If you get the error when trying to accept an invitation in an email attachment, it's because the organizer didn't properly create the event.

    Check USB connections
    If there’s an issue with the USB port, cable, dock, or hub, or if the device becomes disconnected during restore, try troubleshooting the USB connection, then troubleshooting your security software.
    Common errors: 13, 14, 1600-1629, 1643-1650, 2000-2009, 4000, 4005, 4013, 4014, 4016, “invalid response”, and being prompted to restore again after a restore completes.
    To narrow down the issue, you can also change up your hardware:
    Use another USB cable.
    Plug your cable into a different USB port on your computer.
    Try a different dock connector (or no dock).
    Add (or remove) a USB hub between your device and computer.
    Connect your computer directly to your Internet source, with no routers, hubs, or switches.
    If you see your error after changing your USB connections, continue to the next section to troubleshoot your hardware.

  • I cannot close my mail on Mac Air. How do I resolve the problem?

    I cannot close my mail on mac air. There is a message appearing "the Message Design" How do I resolve the problem?.

    FYI - clicking the red dot will not Quit an application that can have more than one window open. Mail is such an app. So are Safari, Pages, Numbers, Keynote. The convention for quitting Macintosh Applications is either command-Q on the keyboard or, if you're a mouser - File->Quit. On the other hand System Preferences, Calculator, DiskUtility and Face time are examples of single window Apps where "closing the window" Quitis the program.
    The confusion is more common among WinDUHows to Macintosh converts.
