• analog input offset USB-6009

  Hello

  I use several USB 6009 units and with some of them seems to have some lag in differential mode, I with 0 to 1V range. Grounded the two terminals with resistors as shown in the tutorial OR «wiring field and noise review...» "seems to fix the problem for some of them, but for those that I have not the slightest compensation first, the ground gives me offset.  Can someone please suggest?

  Thank you

  DS

  DS,

  Please submit your question in the Forums of NOR. Are you trying to take a differential measurement? What features are you try to measure it and what channels the drop-resistance work with and what channels do they not work with?

• analog input on USB-6009 - what potentiometer to use for this test?

  Hello, I am referring to this video

  http://www.YouTube.com/watch?v=rSNRG_Ddl1s

  What is the resistance (ohm) the potentiometer used in the film?

  Thank you

  Luke

  They know the author of video ...

  Since it is connected to the output of 5V to the DAQ card, you don't want to use too low of a low value.

  A pot more of 500 ohm must work safely. Exact value is not critical for this demonstration. Rear wiper terminal must be connected to the analog input, the other two legs go 5Vout and GND.

• measurement of the current usb or 6009

  I'm trying to trace the evolution of a CCCV charger while it loads a 60V lithium-ion battery. I know that the charge rate is (1/6) C and the nominal capacity of the battery is 26Ahr resulting in a current of 4.33 has during this constant stage. I have the NI USB-6009 case and that e/s analog devices is estimated at 50 Ma, so I can't connect a thread of the charger directly on the device OR. I was thinking of buying a CT that connects directly to the material NOR and run the (+) lead from charger through the CT, as it charges the battery. What is the best way to go with the flow for a complete charge cycle? What are the other options to draw current developments?

  A CurrentTransformer will work with current alternative...

  A CT compensated with element Hall (research LEM) can measure AC / DC...

  I'd look for a Hall Allegro current sensor... has a galvanic isolation output, and the output is the input range 6009.

• Input/output USB 6008 test failure

  OK I am posting this for the third time, but whenever I go back to the home page of the forum, I'm not able to find my post. If by chance I created duplicates than apologies.

  IAM in train to test the USB-6008 case I just got and decided to hang the analog of the analog inputs and see using labview VI.the wiring was done as:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/USB%206008%20wiring_zpss2b7hql9.jpg

  the problem is that the labview VI did nothing, so I go to NI Max and try to see in test panels. But I get 1.4V constantly my same analog input value when I'm changing my analog value:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/AIO%20screenshot_zps9beiimbj.PNG

  the analog output works very well since I plugged it to my multimeter and I can see the tension that I see on this Panel of test:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/AO0%20screenshot_zpsqpei37bw.PNG

  I created an entry/exit of the tasks; screenshots of them are:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/task_ai_zpsix5se9yg.PNG

  I am quite frustrated with all this since I'm unable to access my actaul draft. I know that 1.4 V value is from the device itself; as in the manual it says 'internal resistance divider can cause the Terminal to float at about 1.4 V when the analog input terminal is configured as a CSR', but the funny thing is that I use it in differential mode so I don't know what to do and any help is appreciated.

  BTW, I did a google search and there are other tutorials onlune who seem to do exactly what I do and they seem to work very well; so I don't know what else to do.

  Please don't host images on some odd third-party site. Attach them to your message.

  I don't understand what you've done. The 6009 can produce only a signal of CSR in order to set up the differential input makes no sense. If you want to measure something different, try a simple battery.

• Python USB control 6009

  Hello

  I'm trying to use python (with types) to control my USB-6009.  The goal is to write an analog voltage and then read the voltage across an entry with the possibility to change the number of points on average and the number of times that it is repeated (sweeps) averaged analog analog input Board.  The problem is that, as we increase the number of times the voltage ramp is repeated (scans), we get a time-out error (call nidaq failed with the error-200284: ' some or all of the requested samples are not yet acquired).  This value confuse us because the scans are in a larger loop and the function of data acquisition should be the same if there is 10 scans (work) or 1000 scans (crashes).  Any ideas would be greatly appreciated.  I have included the code below for reference.

• timed equipment digital input with usb port and windows

  Hello

  I have a data bus 16-bit I read in a computer windows laptop. There is a strobe data to tell me when to read the data I want. The STROBE will remain high for 1 time of speech to 10 Mbps (about 1 microsecond) the flow rate is much lower than the speed of the bus. I looked into the usb-6501 but it does not support hardware timing and mark will not work at this speed. Is there a usb device that will do it? Maybe a pc card? FireWire?

  Please don't send me to pages on device selection. I looked and I couldn't find what I think I want to.

  Thank you

  Charlie

  Hi Charlie,

  The sampling rate overall max for USB form factor is 1 ms/s or 1.25MS / s for a single channel. The box USB-6251 takes in a 16-bit input. For higher sampling rates, you will need to use a PCI or PXI form factor.

• 201003 - USB error 6009

  Hello

  IM using the USB-6009 to recover my data.

  After a 6 month break, when I ran my VI

  A dialogue box that says "loading lvlib" arose before the opening of the VI.

  When I run the VI I get an error '201003' (Image 3) (it was working perfectly well before)-the only change is the upgrade of windows 8.1 for windows 10. (My Labview Interface with adurino seems to work very well)

  I looked at the following links for more information-

  1. http://www.ni.com/white-paper/52818/en/

  2. http://www.ni.com/download/ni-daqmx-15.5.1/6100/en/

  3 http://search.ni.com/nisearch/app/main/p/bot/no/ap/tech/lang/en/pg/1/sn/catnav: of, n8:3.1637, ssnav:su...

  I've updated my drivers NI DAQmx, but not the same error.

  When I look at the devices and inetrfaces - the status shows "absent" (Image 1) - after updating the driver, "ASRL 10::INSTR LPT1" said as 'away' status (Image 2)

  When I test the single device - it removes.

  I'm a little confused as to what to do next? I should return to windows 8? Should I reinstall the USB-6009? Am I missing something?

  Any help would be great.

  Thank you

  Thank you attach your VI and providing additional information.  Here are some facts that might clarify things for you.

  • The only version of LabVIEW which is certified for Windows 10 is LabVIEW 2015.  LabVIEW 2012 came out 3 years before 10 Windows, and is not certified to run on this OS.
  • If the USB-6009 case works with LabVIEW, when you plug it in, MAX (measurement and Automation Explorer) should "wake up" and offer to set it up for you.
  • If you don't have MAX on your desktop, then you certainly won't be able to run your VI.  If you do have MAX, you should be able to open, see your USB-6009, open the test for her panels and manually set to acquire data on an analog channel.  Try a continuous sampling at 1 KHz, 1000 points - you should see a 'noisy' plot change once per second.

  Assuming that my assumption that you try to run your code on a PC running Windows 10 that is correct, I think you have two options:

  1. Start with a PC running Windows 7 x 64 (think Re-imaging your PC 10 Windows, if necessary), and then reinstall LabVIEW 2012 (32 bit).
  2. Continue with 10 Windows PC, but install LabVIEW 2015, DAQmx including (from device drivers).

  Looking forward to learn more about your system, including (a) if my assumptions are correct, (b) what path you chose to try to get this to work, and (c) what happened.

• Measures of true bipolar voltage with USB 6008/6009

  The 6008 or 6009 to make true bipolar (positive and negative voltages referenced to GND) measurements?  If not, what is the solution to purchase cheaper data this feature?

  Thank you.

  The question of unipolar vs bipolar vs bipolar Pseudo-aleatoire also was mentioned in this thread.  The 6008 6009 use bipolar-only mode and load the setting differential input or CSR.  Please note that {unipolar / bipolar / Pseudo-bipolaire} is independent of {differential / CSR / Pseudo-differentiel}.

  The 6008/6009 don't use 'Pseudo-bipolaire', which means that each differential input should be positive with respect to the ground.

  Best regards

• How the buffering is the USB-6008/6009 has?

  How many readings can be stored internally until the unit overflows.  Pointers to info that describes this would be appreciated.

  Thank you.

  512 bytes.  256 samples.  This is specified in the USB-6008 user manual.  See Specifications, input analog, AI FIFO (page 24).

  You can also always determine this programmatically.  Create a task of the desired type and query the size of the buffer in a property DAQmx buffer node.

• can I use labview 8.01 whit usb device 6009 with vista home

  can I use 6009 with labview 8.0 and Windows Vista home OS usb device?

  LabVIEW 8.2.1 is the first version that is compatible with Vista. While 8.0 could operate, NOR offer any guarantee.

• Example of Code OR-DAQmx (C/C++) for playback of 8 differential analog inputs on USB-6215?

  Are there examples using the API C/C++ of NOR-DAQmx in an application that illustrates how to read all 8 analog channels (differential) on a device USB-6215 or similar?  I can find examples to read only one channel, but nothing for multiple channels.  When I try to read all 8 channels, I get only entry on the first channel.  Any help would be appreciated.

• Input microphone USB is overwhelmed to input device

  I have connected a device to USB audio interface Behringer 'U-Phono UF0202' on a computer Toshiba Qosmio X 505.  The unit takes analog tape recorders and entries of digital signals to the USB port.  The device is automatically identified and drivers not installed - no software from the manufacturer, just Microsoft drivers.  Drivers Microsoft treat it like a USB microphone and audio interface Behringer way dominates the entrance.  The level parameter must be set to 2 or 3 to prevent the sould indicators of level of maxing out.  I have to force another driver for this device that has more performance than a microphone?   If so how do you get the driver on the right USB port whenever you plug in the device?  Thank you.

  I found the plug-and-play standard configuration has continued to overdrive at the entrance.  I installed the drivers from Behringer and it works well with the right device selected on the USB port.  I'm not using Audacity; I use other software to record.

  Thank you.
