• How to find the time between two channels of entry in the data acquisition card or pci 6036

  Hello

  I read a lot-related posts on the simultaneous measurement of two input voltage of similar channels in map data acquisition. I know that the best material is "simultaneous measurments of the Series DAQ cards" but I only pci data acquisition card 6036 and I try to understand what is the time between the reading of the two channels . This period is always constant? (must it rely on a voltage (amplitude, frequency, waveform..). I send the sine wave (s) to the two channels and read the values of V, if they read the same value, the difference should always be zero but I get-0,002 to 0.002 Volt difference (I must find a way to convert it in time). A screenshot of my VI is attached. I wonder how I can accurately measure the time delay between the channel.

  I am open to any suggestion, my final goal to read exactly two channels at the same time ((ou connaître le délai exact donc je peux correspondre les données correspondantes étant donné le temps de retard))

  Hi spinup,

  better you should post your question in the forum of LabVIEW, LabWindows/CVI is used

• How to configure HP ENVY 700 - 210xt to install the graphics card EVGA 650 TI boost.

  Can someone tell me how to install the graphics card EVGA 650 TI boost in the

  HP ENVY 700-210xt

  Product number: E9G99AV

  I replaced the power supply with Corsair RM 650 watt power supply that works very well. Now, I want to go to the graphics card EVGA 650 TI boost. Except, I can't get the driver to load with period of installed equipment. When I put the card into the PCI 16 x slot the computer starts with a blank screen. I pass the DVI video port old computer and the new port card white screen of same at startup. If I turn the PCIe port disabled in BIOS, it starts with the embedded video, but same thing impossible to load drivers that are not able to locate the new video card hardware. Makes me crazy! I don't know that I don't know how to configure the Bios correctly or something. Can anyone help?

• How to control several input channels analog daqmx for data acquisition trigger (all on the same SMU-6368)

  Using the SMU-6368 module, I would like to monitor the analog signal on multiple channels and trigger on several channels - relaxation and acquisition channels is all on the same device. Probably going to be sampling at 200 kHz and more. FM LV 2009 2012, with SV toolkit in Windows 7.

  If SW trigger is the only way to follow, there example code shows how to manage the block size, etc.. ?

  jkessler,

  Yes, the example was in 2012.  I didn't get what you asked for in your first post because I didn't know you wanted to ANY channel to trigger acquisition of all channels.  It is not possible at the hardware level, because you cannot specify four channels as the command source. This will be implemented in the software.  I recommend the reading of all four channels and neglecting data until you determine that one of the channels reached your threshold value.

  Kind regards

• Configure a load cell connected to multifunction DAQ

  I'm trying to connect a LCDH Omega 10 K scale by a module of constraint Dataforth SCM5B38-37 then AI0 gauge on a USB-6251 multifunction data acquisition.

  In addition to the load cell, the application will use a pressure sensor with a strain gauge bridge module plugged into AI1 to read the pressure of hydrulic.  The pressure transducer using a measure of the force will be calculated and compared with the reading of load cell.

  Currently, the USB-6251 box is configured to read analog voltage on AI0.  The scale is then performed using linear Fit.VI.

  Review the example Bridge - entry continues shows some additional controls may increase the accuracy of the reading.

  Unfortunately trying to use the DAQ Assistant only added to my confusion of the best practice in the acquisition of a signal from a load cell.

  __________________________________________________________

  Here are some of the questions I have...

  What is the best practice implement a load cell using a full bridge strain gauge conditioning module labview?

  What is shunt calibration?  Is this similar to the USB-9237 DAQ modules-specific?

  How do you know if your sensor is set up like a full bridge, half bridge, etc, the document load cell does not it?

  You can use the VI delete DAQmx perform bridge?

  _________________________________________________________________

  I don't know, I understand all the information of the map calibration either.

  Why is there resistance to entry and exit values?

  What is the value of the zero balance signafiance?

  Hello!

  I was looking into your question and found a few links that might help you configure your system. The first is a white paper that discusses some of the basic concepts of the gauges of constraint and their use with LabVIEW, shunt calibration and also covers some of the resistance values you see:

  http://www.NI.com/white-paper/3642/en/

  As you can see in this article, we have some specific hardware, built for the kind of measures you take. Because these devices are manufactured specifically for this application, they would provide better and more reliable results. That being said, you can configure your system with your USB-6521, it might not be as accurate as one of these systems. To set up your measurement system, rather than defining the analog input as a measure of deformation, you want to use the voltage custom with the option of excitement. This article treats this yet:

  http://digital.NI.com/public.nsf/allkb/C66F92BDE229F45A86257B6D004D6033

  We get you your data in the form of Volts/Volts (this document addresses more info on bridge probe scaling: http://zone.ni.com/reference/en-XX/help/370466W-01/measfunds/bridgescaling/), , but you should make sure you standardize this value to the excitement. Devices such as the NI 9237 provide the voltage and can take this known value in to account within the program, but you may need to do this manually for your application. Here is additional information on the NI 9237 and how it is configured to read information from strain gauge:

  Regarding the configuration of unit load and the information, you can try to contact the manufacturer for more information!

  Thank you!

• How can I know how much memory is on my card data acquisition OR 6133?

  I have a NI 6133 data acquisition card, but I don't know if this is the model megaechantillons 16 or 32.  How will I know?

  Thank you

  Kevin Brown

  Hey Kevin,

  You should be able to find it by reading the attribute Input.OnbrdBufSize (property node DAQmx buffer in LV, DAQmxGetBufInputOnbrdSize in the C API).  To do this, you will need to create a task to HAVE.

• How to program dynamically data acquisition?

  The question may seem, I want to dynamically change the settings of a data acquisition card (DAQmx). The idea is to have a loop event caputures GUI and the other while answering the while loop DAQ events. It's something like loops PRODUCER-CONSUMER. However, I can do all thing once, but not on the fly. Any suggestions as to how we can achieve this?

  Thank you

  Thanks for the comments. I solved the problem with the traditional approach. Here is the graphic interface to work.

• How interface bronkhorst RS232 communication flowmeter in DIAdem DAC?

  Hello

  I am Thiyagi.I am working in WABCO INDIA Ltd. I bought Bronkhorst Flowmeter. I use the tiara DAC Professional version. I want the meter to DIAdem.Flowmeter of the interface have a RS232 communication. In my pc, I have a COM1 port. DIAdem DAC which icon I want to use to connect the flow meter.

  Hello hmongz

  You can already succeeded, but still, here's what I used to do:

  I could do this with flowmeters mass Bronkhorst and Brooks, and had a pretty good success using their method of DDE (dynamic data exchange). To do this, download their software from FlowDDE of Bronkhorst.com, start the DDE driver and he can communicate with the MFM. Once it works, insert a DDE lockk in CAD DIAdem, configure it appropriately and it should work.

  Greetings

• How can I check if DIAdem a 32 or 64 bit version?

  Hi all

  How can I save a DIAdem script if a version of 32 or 64 bit? Is there a variable or a function?

  I need this show to avoid loading COM 32-bit objects.

  Thank you

  GEMÜ

  Hi GEMÜ,.

  The variable you are looking for is APPLICATIONBITNESS. The variable is available in 2014 tiara but without documentation. This documentation will be available in 2015 tiara. The variable is read-only and returns an integer (32 or 64)

  Hope that helps

• How to configure firefox to open outlook e-mail links in a new tab instead of having this "crush" a tab currently open?

  How to configure firefox to open outlook e-mail links in a new tab instead of having this "crush" a tab currently open? For example, that I have a tab open and consult the information about this. An email comes in via outlook and I want to read a confined link. When I click on the link, it will open in the tab I have currently open. I would like to open it in a new tab.

  You mean Outlook, the standalone version and not the new iteration of Live (live.com) mail to Outlook.

  I think that the default is to open in a new tab in the last active window, but you can check it out here and replace the default value:

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

  (2) in the search above the list box, type or paste link.o and make a pause so that the list is filtered

  (3) double-click the preference browser.link.open_newwindow.override.external and change it to 3 and OK change

  The options are:

  -1 = apply the setting in Options > general > tabs of external links (default)
  3 = open external links in a new tab in the last active window
  2 = open external links in a new window
  1 = open external links in the last active tab replaces the current page

• How to configure Firefox 4.01 to save all tabs when closing the browser?

  In the previous version 3.x.y to Firefox, when I closed the browser, he asked me if I wanted to save my open pages / tablets before closing. When I open the browser again, then it rebooted all previously open tabs / pages. In the version 4.01, before avant de fermer close the browser warns me that I'm closing multiple tabs, but when I restart the browser once again, it does not load the already open tabs. How to configure the browser to behave like the old version of 3.x.y, that is perfectly save all open tabs and load these new opening to restart the browser?

  Firefox stores now always the old session, and you can access it by going to the history menu and selecting "restore previous Session."

  If you always open the last set of tabs, another approach is the following:

  1. Click on the orange button Firefox, then select options to open the options window
  2. Go to the general Panel
  3. Change the setting "When Firefox starts" to "show my windows and tabs from last time '.

• Cannot acquire with cDAQ in hardware mode timed using DIAdem DAC

  Hi all

  I use DIAdem DAC to acquire the cDAQ + 9225 + 9219. 9219 acquires the use of single point mode that works very well. However, I tried to acquire waveforms 50 kHz 9225 with the file attached dac. However, I found a problem on the block of the clock, as shown below.

  

  How could I solve this problem and gain the waveform with 9225 using DIAdem DAC?

  Sincerely, Kate

  Hello Kate,

  You must connect the NIDAQ-In1 exit the Save block block. In addition, you must change the parameters of the horloge1 block. The material is always measured in mode "DAC-kernel". "The software clock" is used for frequencies of up to 10 kHz clock (depending on the material and the PC). If you want to measure more quickly, you can use the "Clock" mode

• How and where should I go to find out how to configure my joystick so I can use the joystick to use the flight simulation game that I bought from microsoft?

  I can't find out how to configure my joy (attack3) stick to play Flight Simulator. I don't want to use the keyboard on my computer to steal the game... Where can I find the instructions on how to configure and use the joystick?

  Hello

  1. what happens when you connect the joy stick?

  2. do you get an error message?

  3. what version of Windows are you using?

  Perform the steps mentioned below and check if that helps:

  Step 1:

  Flight Simulator x: using a gamepad

  http://www.Microsoft.com/en-US/Download/details.aspx?ID=16624

  Step 2:
  Usually, vista Windows 7 will find and automatically install the necessary drivers when you plug your game controller into your computer.

  (a) connect the joystick to the USB port via the adapter.

  (b) see if it is detected.

  (c) Windows should recognize the new hardware and set in place to work properly.

  If this isn't the case, install the relevant drivers for gamepad for the manufacturers Web site.

  Step 3:

  I suggest the following steps and check for the device.

  1. in Control Panel, open game controllers. To do this, use one of the following methods:

  a. click Start, typejoy.cpl in the Search box and press ENTER.

  2. click on your game controller, and then click Properties.

  3. on the Test tab, test the game controller to verify functionality.
