TDMS properties show polynom scale even if DAQmx ist to linear bracts

I aquire data with DAQmx and write the data to a PDM file. The input channel is updated with the linear scale, as shown in the 'Code Skalierung' image. Unlike this linear scale of the channel-properties file TDMS show a scale polynom with totally different values.

How do I adapt my HAVE linear and the properties display the appropriate scale values?

To add information to Andy, many devices require a polynomial scale is because the analog-to-digital converter (ADC) on the device has non-linearity at the top and bottom of the range ends.  A linear scaling of the raw data would not account for these non linearity, which is their precision and very high and very low readings.  So instead, we use a polynomial scale that reflects much better the actual physical properties of the device.

  • Full scale PXI - 6254 DAQmx Analog Input

    Hello

    I use PXI - 6254 Board to read the analog inputs. Configured channels using DAQmx create Channel.vi with sub parameters.

    In the configuration: CSR

    Min: 0

    Max: 10

    Units: Volt

    I read the channel using DAQmx Read U16 2D with the sample of 1. I expected below the values.

    data of 0 v = 0

    10 volts = 65535 data

    but it gives 10 volts = 31544 data. Please let me know why.

    If I set up the channels with the settings below:

    In the configuration: CSR

    Min:-10

    Max: 10

    Units: Volt

    He always reads the same values (data 0 v = 0, 10 volts = 31544).

    Please let me know, how I can get 10 volts = 65535

    Thank you

    Hi LVTestek,

    The PXI-6254 is not an interval 0 to 10 V input V. The specification of 625 x OR lists the available input ranges:

    Entry level of ± 10 V, ± 5 V, ±2 V, ± 1 V, ±0, 5 V, ±0, 2 V, ±0, 1 V...

    When you set Min = Max 0 = 10, DAQmx chooses the smaller input range that allows to measure signals between 0 V and 10 V without clipping. On the PXI-6254, the smaller input range that meets this criterion is the range of ± 10 V, where - 10 V corresponds to-32768 0 V corresponds to 0 and 10 V corresponds to 32767.

    However, there is an additional complication: ranges entry on M Series devices are slightly wider to accommodate the software calibration. Otherwise, gain of a device could reduce the scope of actual entry, and offset error would move the ends of the effective input range. If the [-10 V...] 10 v] range on your PXI-6254 could be more like [-10.3 V...] 10.4 V]. 10 V is actually to 31544, rather than 32767. On another PXI-6254, 10 V could correspond to a different value of gross / scaleless and 31539 31552.

    Another side effect of calibration of the software, is that the data returned by the flavours 'raw' and 'no' to the VI DAQmx Read are benchmarked. The KB explains further: is raw data DAQmx calibrated or chipped?

    If you can modify your application to use one of the flavors "on the scale" (F64) VI DAQmx read, which should save a lot of effort. If not, could you explain why your program requires readings without scales/bullies? The right approach depends on the requirements. For example, if you want to save the data in a file and you need to reduce the file size by using raw data / scaleless, configuration DAQmx to save data directly a TDMS file can meet your needs. If you update an older application to work with DAQmx and M Series, a different approach may be more appropriate.

  • FF28 upgrade & all the addons are showing that off, even if they are enabled

    Upgrade to FF28 & addons all + userscripts show that disabled, even if they are enabled.

    I already tried to delete:
    addons. JSON
    Compatibility.ini
    Extensions.ini
    Extensions. JSON
    Extensions.SQLite

    All that done as a cause of Firefox go in a "reboot several times 50 times more than one by one and each time asked me to manually install each addon. The process took more than 5 minutes and left me very impressed by the ability of Firefox bugs.

    End result? I am still sitting with the same problem. All the addons are showing that off, when they are turned on in fact. I cannot change them, uninstalled them or install new addons.

    PS. Oh and I write of Sleipnir not Firefox because Firefox has refused to work with the buttons on this page for some reason any (yes I'm allowing scripts in NoScript)
    PPS. Oh and my old account here for some reason some refused to open a session, even though I wrote the user name and password and I tried using the user AND email for the login process. Overall, very impressed with the services of Mozilla for now. I really want to move to a different browser.
    PPP. I have over 300 tabs open in Firefox, so can't go on the road to reset, because Firefox has no way to record a session.

    Honestly, Firefox must be transportable by default. What the point of having a browser that you spent 12 months + customization with 300 + tabs open, if your Windows partition is damaged and you cannot retrieve your tabs because it is installed? I will never use the installed version of Firefox again because it is impossible to save. If I had been using portable Firefox at the time where I could have accessed my XP partition corrupted with Ubuntu live USB, back up the folder and be good to go on my new install of Windows 8. Instead I had to start from scratch. That's what you get for not using of portable software.

    This is resolved. The steps that I followed:

    1. Ignore all the Internet advice and find a way to do it myself because no one else seems to know anything about Firefox.
    2. Save the entire Firefox portable folder making it a 7zip file
    3. Disable all addons
    4. Download the latest mobile Installer
    5. Install using the portable Installer but navigate up to the existing installed cell phone directory
    6. Open portable Firefox after updating
    7. Update all addons (do not select all again)
    8. Restart Firefox
    9. Now activate the addons, then restart Firefox

    Note: installing addons now I find that I can't add using the button 'Download' for the addon, I have to copy the URL of the button, paste it in a new tab and press enter

    With all due respect, you are incorrect. You simply did not notice before D drive. D drive is a logical drive. To the best of my knowledge there is no way to prevent it from the show. However, simply disable the system for D drive restore.

    A scanned document is an image; You can't find a picture.

    If the image contains text, recognition of characters (OCR) will convert the 'text' in the image in real text (searchable, editable).

    OCR can be performed automatically when converting a PDF to Word, using the ExportPDF service.

  • Unified junk folder don't show Yahoo mail even when added manually

    I put folders for unified. This shows the single folder of junk mail with the name of accounts as its subfolders.

    The list in the left pane is a bit like this:
    Junk
    -GMAccount1
    -GMAccount2

    All accounts are IMAP accounts.

    I also have Yahoo IMAP account where the Junk folder is designated as mass mailings.

    Default thunderbird does not believe in junk e-mail, so what I do is:
    (1) right-click on the unified junk e-mail folder and go to properties
    (2) the title of "Select records to search" I manually add the mail folder in bulk for Yahoo accounts.

    After adding, I expect that the inscription on the left side would become:

    Junk
    -GMAccount1
    -GMAccount2
    -YahooAccountName

    But it does not show YahooAccount as a subfolder. (Even after you restart thunderbird)

    But surprisingly, when I click on the unified junk of top-level folder, then it shows emails in "Bulk Mail" in the right pane.

    Which means there's a minor display bug that does not display the folders included in the unified folder.

    Please let me know if there are good solution or please fix the bug.

    Thank you.

    I found a solution:

    Goto YahooAccount properties
    Junk mail settings
    Destination and retention
    Check the movement new unwanted messages to:
    Other: Bulk mail on YahooAccount
    Restart thunderbird

    This average thunderbird knows it of the junk mail folder, then starts it displays under folder "unified Junk."

    This solves the problem, but I guess this shouldn't be necessary.

    Any account mentioned in "Select records to search" (in the properties of the unified folder - as mentioned above), should appear under this "unified record."

    However, I managed to solve the problem of windows in SafeMode via msconfig startup.  This gave me access to the file, and security settings showed that it was owned by the deleted user's profile.  I deleted this user of all files and restarted in normal mode and the problem was solved.

    As mentioned above, it ONLY shows Max Turbo frequency 2.8 GHz when it runs in Turbo mode. Normally, it will only work speed. You can crank it for rendering video example using high-end video editing software. And please note, do not work to its fullest every day, he'll kill himself faster.

  • Police problem - all fonts show as "BOLD" even if the bold has not been successful.

    No matter what I chose to compose e-mail, for example, Times New Roman, size: 12 Pt, police the selected font will appear as if I clicked on the B for the bold. The only size font which DOES NOT appear as "BOLD" is the 8pt font. This problem of police comes little matter the type of font, I chose. For a short time today, the appearance of the police showed that the type was in CAPITAL LETTERS, even if the CAPS LOCK SHIFT key was NOT enabled. I could not return to the low case letters, so I restarted my computer, and only the UPPERCASE function had returned to normal. The "BOLD" type always appears any police, I chose, UNLESS I reduce the font size to 8 Pt, for each single font from the list of fonts in Outlook Express. Can you please explain how it happened, and most importantly, how to fix? Thank you.
