• How can I filter the noises of thermocouple using a TC-2095 and SCXI - 1102c?

  Hi all

  I currently have four TC - 2095 s connected to the SCXI - 1102c inside an SCXI-1001 chassis cards. These thermocouples are floating and I get a good amount of noise (400 Hz 3 phases and same 60 Hz noise) when we turn on some equipment such as fans, and fans. Using this current set up, how can I filter the noise? Or I would need to put in place a new hardware configuration (e.g., the SCXI-1102 cards)?

  Hi RALoo,

  The 1102 C has a lowpass filter with a cutoff at 10 kHz frequency, so you will not be able to filter into the material with your current configuration.

  Your first option is to use a software filter.  LabVIEW has several functions that do this. More information can be found here: http://zone.ni.com/reference/en-XX/help/371361J-01/lvanls/filter_vis/

  The second option would be to change to SCXI 1102 cards as you suggest.  The low-pass filter of the 1102 was a cut-off adjustable to 2 Hz frequency, which will stop the noise of 400 and 60 Hz don't affect your readings.

• Playback issues of Thermocouples a 9214 in EtherCAT 9144 chassis

  I have an SMU-1078 chassis with an SMU-8135 controller and chassis EtherCAT 9144 with multiple C-modules, including a couple of 9213 9214, running Veristand 2014 and 2014, inertia. I updated last week so I think I have the latest updates for the hardware and software.

  The problem I encounter is that I can read my Type K thermocouples with Thermocouple 9213 modules, but when I connect them to the Thermocouple 9214 module, I see only TC0 change and the rest of the TC 9214 channels are 0 ° c. tried to use high speed and high resolution modes, but no difference. I also moved the module in slot 8 in the EtherCAT chassis, also without success. Then I moved the 9214 with its connector and thermocouples to another machine with a chassis cDAQ in 9188XT and I have read all the thermocouples with NI MAX. This proves that the module is working and that the module connections are good.

  I need to use the 9214 because of his ability to handle the higher common mode voltages. I need help. Please, I beg you.

  Thank you in advance

  It ended up that I had to download the last update, 14.0.1 for the NOR-RIO. This solves the problem. I did have to reinstall Veristand, Labview, or any other driver.

  Thank you very much for your answers.

• WSN MAX, J-type thermocouple and serach time node issues

  Hi dear all,

  I use the WSN starter kit, I am able to work well on it, but have some problems and you smart guys do look in those.

  1. once I installed 1.2 WSN software module poineer, I am unable to see Remote System tab in the tree of MAX, only my system tab is displayed. Even if I am able to see in my lvproject, to develop and use the application successfully.

  2. the J type thermocouple which came once I set TC0 + and TC - of the WSN - 212 node according to documentations, then in Labview VI, I see in the temperature value 273.56 ambiguous as - values and change them to-244.67 as once that I touch at its end. My node is set by default to the range of temp type J and Celcius, click right property tab.

  3 How long the knots will search gateway once its out of the range of gateway or I power off of the entry door? I experienced his seraches led for about 1 min then sleeps for 1 min at the start and then sleep time increases. I did this for 3-4 hours but after that 7-8 hours I couldn't see any LED flash for the search of the entry door. I needed to push button on the node, and then I start seraching.

  Kindly help me on these issues. More will come once I have will probe deeper into the system.

  Thank you & best regards

• Configuration of two materials for a software

  Hello

  We worked with two vehicles controlled by Labview 2011. Each vehicle has an equipped that nor-9188 cDAQ of a module of digital I/o and a thermocouple module. We have appointed the first chassi to 'Vehicle' and "MotorControl" and "Thermocouple" max modules. Then we created a software that allows to control the vehicle, everything works fine on a chassi.

  However, when connecting to the chassi 2 Max we get the problem that the chassi cannot rename the same name as the chassi, same if chassi 1 is not connected. We can also not change the names of module in chassi 2 because that name already exists in the chassi 1.

  How can we solve this problem? It must be pretty common that there are multiple identical devices that must be controlled by a single software. Basically, it is not good to my knowledge pretty good know. : mansad: could you please advice me?

  Kind regards

  Mattias

  Names of DAQmx device for all devices in the system (including disconnected devices) must be unique.

  Solve you this problem by giving all distinct names: for example, the first may be 'Vehicle 1' / ' MotorControl 1 "/" Thermocouple 1 "and the second can be" vehicle 2 "/" MotorControl 2 "/"Thermocouple 2"." "" ""»

  There are two ways that you could deal with this in the software. If you go with the above, for example, you can simply add the number at the end of the device name prefix, as follows:

  Another strategy would be to put all device names in a cluster (so you can spend all your information around like a group configuration).

• With the help of several NI USB-TC01 Thermocouple measuring devices

  I am currently set up with 1 NI USB-TC01 (http://sine.ni.com/nips/cds/view/p/lang/en/nid/208177), and everything works fine.  My question is, can Labview control multiple TC01s simultaneously or I have to buy the NI USB-9211 has (http://sine.ni.com/nips/cds/view/p/lang/en/nid/201881#) to manage multiple thermocouple measures at the same time?

  Thank you

  Ben

  Ben,

  I didn't know we even had this device but I think that all of the information you want are in the link below.

  http://digital.NI.com/public.nsf/allkb/7A9DAE5554C9D503862576FC005A3908

  If you use the built in program, it is four devices, if you are using LabVIEW, you are limited to 127 devices.  I don't know if several windows built-in software should be used if you use a LabVIEW.

• Temperature measurement and the CJC using thermocouples on a USB - 6229 BNC

  Hello

  I'm trying to get the measurements of temperature using type K thermocouples on the box nor usb-6229 BNC. SignalExpress software doesn't let me choose 'Built In' to the Source of the CJC. So, I must select 'Constant', which means that I then have to follow the evolution of the temperature during the day with a separate meter and adjust the value of CJC accordingly to maintain an accurate reading. Is there a way around that to avoid having to monitor the room temperature at the junction?

  Thanks in advance

  Mike

  Hi Mike,.

  It seems that you have managed to find a solution for you have this problem, which is great news.

  However, for future use, if you had bought the 6229 with massive ending (rather than the interface BNC) then you might have interfaced unit with a block of connection SCB-68 (see link)

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/1180

  The SCB-68 has a CYC source built-in, so you might have used in conjunction with 6229 (mass layoffs).

  A bit of in the way, but I thought you may be interested.

  Best wishes to you all

• 9211 thermocouple change during execution

  Hello

  Is it possible to change the type of thermocouple (run-time) to a daq module 9211?

  Thanks for the tips,

  Sincerely, n

  What you want to do, is use daqmx features to create your virtual channel within your labview program instead of starting from MAX.  It is very easy to do, and then you can change any setting of the virtual channel that you like.

  This is a simple example of how create the virtual channel.  It is a simple software timed using this virtual channel acquisition.  Notice how you have all the options of the TC channel in virtual channel creation function.

• Noise on the readings of thermocouple on the NI PCI-6225

  Hi all

  I have a problem with what appears to be static electricity caused by noise on thermocouples.

  We test with a sand as a medium flowing through a plexiglas window and measure the temperature in the stream. The interaction of mixture air/sand flowing through the plexiglas creates a significant amount of static electricity and our thermocouple readings are severely affected. Is there a way to filter the signal so that my data and off-scale obvious signal analysis tools ignore?

  The filtering I see seems to apply only to high frequency noise. I would like to cut the signals from the TCS to ignore all of the above measures 700DegF and under 32Degf.

  Thank you

  Hi Emi_emii,

  It might be useful to see what the current state of your VI acquisition is - just to get an idea of your overall architecture. I see a couple of alternatives.

  1. You could do some external signal filtering to get rid of the extra load on your son of thermocouple - see this valuable whitepaper on the topic of wiring: http://www.ni.com/white-paper/3344/en/
  2. The extent of the filtering software, you could use the cooker and force the function (http://zone.ni.com/reference/en-XX/help/371361J-01/glang/in_range_and_coerce/) on your data and the use of the Boolean output to hide your actual data or simply to force your MAX/MIN values

  Hope this helps!

• Uninstall software update Apple says error in seller contact package package unstaller

  Try to get itunes working to make a backup of my faulty iphone before repair.

  First-itunes does not start says error. I'm trying to fix it, who said success but same error when you try to start it.

  Then uninstall completely worked. Then reinstall that seemed to be over except for a message "an older version of Apple software update already exists" then he went down and install itunes apparently had not been completed.

  Then I try to remove the update from the apple software and executed by an error in the installation program - it says there is an error in the installation and contact the supplier of the installation package. Same error if I run the uninstall command line program.

  Try to repair the Apple Software Update of programs & features Control Panel and then try to update iTunes again.

  For general advice, see troubleshooting problems with iTunes for Windows updates.

  The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

  Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

  The more information box has direct links with the current and recent if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit - for older video cards) as a workaround for problems with installation or operation, or compatibility with third-party software.

  Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

• Note crashing - software update 10.0.2

  Hello

  I've just updated my software to 10.0.2 on my iphone 6 and noticed that my plant notes (saved in my @gmail account) each time I open them.

  Everyone has experienced the same problem, how can I solve this problem?

  Thx a lot!

  I had the same problem with my iCloud account notes. What I did to fix it was to stop the synchronization of notes in the account settings and remove them from the phone, then went to notes, and it does not plant.

  When he reactivated redownloaded them all and it was fine. I think it could have been a picture in one of them makes it crash because it seems to do it every time I loaded a specific note with an embedded image. After resynchronization is OK.

  Hope that helps for you
