small pressure with NI 9215 readings

I use currently the cDAQ 9172 map with several modules of inputs/outputs, analog and digital data acquisition. I'm trying to use the 9215 analog input module to measure voltages by a single anemometer. The playback for the anemometer range is 0-1 V. However, for our use, we analyze the low speeds giving no more than 0.2 V.

When the anemometer is attached to the 9215 module it will not register any voltage read unless it has a very high speed (and thus a higher voltage reading). We tested the anemometer with a simple oscilloscope and it records easily tensions low low flow rates, so the problem is not with the anemometer himself.

So these are my questions:

Is it possible that the 9215 is not sensitive enough for the< 0.2="" v="">

There also the problem that the cDAQ-9172 also contains 6 other modules e/s and is housed in a Cabinet and the signal is lost in the noise/interference?

Can I try in LabView itself in order to increase the sensitivity?

A big thank you to all those who can get an idea.

Problem solved!

Apparently, he was the son after all. I don't know what was the problem, but it is fixed and all right.

Thanks to everyone for their suggestions and help!

  • Why some images are displayed as small rectangles with numbers?

    When I visit some sites, some of the images make under small rectangles with letters and numbers on the inside. This issue seems to be with Firefox (see motogp.com_FireFox.jpg, attached), rather than the site because the site displays properly when I get another browser, such as SeaMonkey (see motogp.com_SeaMonkey.jpg,) attached.

    The website, motogp.com is one I visit frequently; It happens on this site. See 2 pictures attached for an example of this problem.

    The box identifies a character not in the police who are using Firefox. This happens usually when a site has changed use images for its icons to use characters in a custom font, you need to download. There are three common reasons for the glitch:

    (1) uncheck the box 'Allow pages to choose their own fonts' here:

    "3-bar" menu button (or tools) > Options > content > button "Advanced".

    If the pages are not allowed to specify their own fonts, Firefox uses the specified here, police who normally does not have the required pictures.

    (2) disabling fonts download. To check that:

    (A) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

    (B) in the search above the list box, type or paste gfx and make a pause so that the list is filtered

    (C) If gfx.downloadable_fonts.enabled preference is bold and user, set false, double-click it to restore the default value true

    (3) extension of block the download. NoScript has a feature to block the downloadable fonts, for example.

    I don't understand the second part of the question, that is to say the second invent.  Add this code and make sure that the popup is removed and then tell us if all your problems are solved.

    I can't move the anchor points on a shape, I've drawn with the pen tool.  There are also small circles with a point in them (think focus), who they are and they are part of my problem? If I open a new document and draw randomly everything is good, no anchor and focus points behave.

    Bubble icons are the widgets corner. You can drag inward to round the corner. They are not part of your problem. If you want to hide them, select view > hide corner Widget. I have a hotkey defined for this menu item.

    If you see multiple bullseyes, you may have your set with the shape selected, that would prevent you from being able to move individual anchor points. Deselect the shape first, and then move the anchor with the direct Selection tool.

  • Small box with yellow question mark!

    I downloaded pictures from iPhoto via documents.  Imported OK, but have since deleted documents images and now when to access the images (in items 11) 'missing file' message and small box with a question mark in it in the upper left corner.  Guess I'd not deleted documents?  Situation is recoverable?

    Thanks Maz

    You are right.  You remove all the photos from its original location.

    The import function simply creates links to your photos for Organizer to find them quickly.

    It is may be recoverable.  In windows, they must be in your trash or the "trash".    T #Just open the tray and select all the files using Windows Explorer and then right click and follow the instructions.  You must restore the files to their original location.

  • How to speed up loop DAQ triggered using NOR cDAQ-9174 with NOR-9215 and NOR-9402

    Hello

    I use LV2010 and NOR-DAQmx 9.2.2. I have a NOR cDAQ-9174 with a NEITHER-9215 4 channel 100 k simultaneous ADC and NOR-9402 4 channel DIO module trigger and reset.

    We run WinXP sp3 on a Dell M4400 core 2 duo @2. 26 Ghz.

    I used the code example NI DAQmx for acquisition of tension with trigger HW. My goal is to try all 4 channels on the 9215 simultaneously when a trigger is received on channel 0 of the 9402, after data is read, I use channel 1 on the 9402 to reset the trigger of the target material.  I have a version of this work, however the maximum event rate is ~ 16/second. I have the Setup 9215 for finite samples / 10 samples per channel which is ~ 400uSec of conversion time and I realize he is above in the appeal of vi, but ~ 50mSeconds worth?

    The target detector can put out up to 1 k / event triggers / seconds.  Only, I received a rate of 8 per second and I added the NOR-DAQmx control vi driver and chose "commit" this did double the rate.

    My question is what is the maximum rate of loop for these devices (trigger/conversion/reading device / reset) and start over? I noticed that just let free the 9215, carried out using the 'Acq & chart internal strain Clk' raised only the rate of events up to 20 Hz.

    Thank you

    normbo663

    Hi normbo663,

    You can get this works far better assuming you have an available counter (there are 4 on the backplane of the 9174).

    DAQ Compact supports the tasks of meter output "redeclenchables" that can be used to generate a finite pulse train.  You can set a task of finished meter redeclenchables output to be used as sample for your task of analog clock.  The task of the meter output will be re-Army (less than 12, 5-25 ns) as soon as it's finished out the last pulse.  The task of analog input would be configured to run continuously, but it would only sample based on the output of the meter triggered.  For an example, see here.

    You can reference the internal counters on the cDAQ without signals through a routing module using: cDAQ1/_ctr0 (right click on the chain counter control, then select i/o name of filtering and check channels internal to add these options to the drop down).

    Thus, with the tips above, you should be able to immediately re - arming your analog acquisition on the 9215 using one background basket counters.  It seems that the second half of the application is to use a second channel on the 9402 to reset the trigger of your DUT.  You can deterministically generate this signal so by configuring a 2nd redeclenchables meter out task (single pulse, but this time).  All you need to do is the initial delay on the appropriate value for your analog acquisition.  Trigger this counter on the same PFI line that trigger you your analog task from.

    Using counters to generate the signals you need in a deterministic way, the loop becomes is no longer a problem (as long as your input buffer does not overflow).  You may need to re-read several triggers at the same time for the loop to keep (for example to read 1000 samples each, which would correspond to 100 triggers 10 samples).

    Best regards

  • Smaller files with an alpha channel

    I made a short video file in After Effects with an alpha channel of several different ways, but I can't to it go below 3 GB. Is it possible to get the smaller file without reducing the quality or the size of the composition? I would like to get the smaller file size to put in the cloud for use in a group project, and / 3GB is not really all that big a file, I have several files with an alpha channel that others need to access.

    The smallest file size with an alpha channel that is always the production quality would be a QuickTime JPEG 2000. Set the quality to about 85 to 90%.

  • No sensitivity to pressure with CC 2015 Photoshop and Wacom Intuos4

    Hi all

    So, I noticed something that had not occurred to me until I needed to use this feature. I've been using InDesign and Illustrator to my most recent work, so I didn't use a whole bunch of Photoshop since upgrading to 2015 CC. When you try to use the Brush tool, Photoshop does not meet with my Wacom Intuos4 Tablet pressure sensitivity. At the same time, my pen does not feather on gum time reverse commute around either. I don't have this problem when using my tablet in Illustrator, so I don't think anything about her trying to use Photoshop.

    I studied the issue and found that many others have had the same problem. But when you try to use the same solution (Windows of ink), I do not know if there is a "most recent" solution

    My specs:

    OPERATING SYSTEM:

    System Info.jpg

    Photoshop:

    Adobe Photoshop Version: 2015.0.1 20150722.r.168 2015/07 / 22:23:59:59 CL 1032107 x 64

    Operating system: Windows 64-bit 8.1

    Wacom driver:

    Wacom Info.jpg

    Model: Intuos4 M

    Version: 1.04

    As I said, I guess that all the other solutions I found were made for previous versions of Windows and Photoshop, so I can't follow step by step with troubleshooting because I do not have the same "destination path", as when I try to save the PSUserConfig.txt file. So I hope that someone has found an update process.

    Thank you!

    Hi rexh7688,

    1. create a Notepad and type:

    # Use WinTab

    UseSystemStylus 0

    Save it as a text file named PSUserConfig.txt

    2. Open Run command and type appdata, and press ENTER key

    3. go to the location:

    Roaming - Adobe - Adobe Photoshop CC2015 - Adobe Photoshop CC2015 settings

    4. move the file PSUserConfig.txt to the folder settings Adobe Photoshop CC 2015

    Kind regards
