I need a portable daq that can measure up to 15 thermocouples that is usb
Hello, a friend of mine that has no experience with labview is asking me about what daq can he buy in order to have a portable thermocouple measuring system. It has to be usb so he can take it along with him and his laptop and that he can connect up to 15 thermocouples. I saw some usb based systems that are specificly for thermocuple measurement but only have 4 inputs. Is there any usb daq that I could use for this application and do I have to additionaly cancel any unwanted noise via programming???
Solved!

Hi, Indeed there's only a usb up to 4 channels to manage termocouples, this is the NI USB-9211A. But I can suggest you something else:
1. You can buy a SCXI chassis and the Control Module USB NI-SCXI-1600. And using a module SCXI-1102 you can handle up to 32 thermocouples. These are the links:

2. Another PAC you can use is CompactDAQ along 4 modules NI 9211 (4 thermocouples each one)

3. And one more solution, probably the cheapest. You can buy any USB M-Series DAQ card for example, NI USB-6251 with the SCB-68 terminal block. You can connect your 15 thermocouples to the analog inputs and use the cold-junction compensation built in the terminal block.
I hope you'll find useful this information.

I have an iMac running OX 10.5.8
I need a portable external hard drive to back it up before updating the software to Yosemite but I can't find anything that doesn't require you to be running at least OX 10.6. Is there a suitable hard drive? I'm not very technical and wouldn't know how to do any formatting so I want it to be very basic so that I can just plug it in. 500GB should be more than adequate.Correct. When you purchase devices, they would have stated the OS they needed to work, on the box. This can be overlooked, but it is very important to check when purchasing.
You current OS, is so old, that they technology build into the new devices, is not something your OS understands. It didn't exist when your OS was created, and therefore you need to upgrade the OS to work with the newer technology of these devices.
10.6 software is not downloadable. You must purchase a DVD disc. You can order it from the on-line apple store

What do I need to do so that I can use the built-in dictionary all the time? My iPad 2's dictionary functions on Japanese e-newspapers but not on the Arizona Republic or other e-newspapers.

Are you talking about the English dictionary? Mine seems to work ok on the AZ republic web page. Does yours not work on all webpages? Does it not work when you type an English word in Notes and then do select and define? -

I have the latest downloadable version of LR5. It crashed while it was createing 1:1 previews during an import. After a Win7(64) restart, it shows a message that LR needs to quit because it can't read the preview files and it will try to fix it the next time is launches. I get the same message the next and every subsequent time it launches so I can't launch LR at all now.
I get that the preview file got corrupted somehow. Is there some way to fix this problem without building a new catalog?Use Windows Explorer to open the folder containing your catalog. You will see a folder with the extension .lrdata. You need to delete that folder and then start Lightroom again. Lightroom will generate a new previews folder.

How can I print directly from my iPad to my new Primax 3260 printer when I have no computer? Do I need a portable one to one Router for the wiFi connection. My Internet is through Telstra 3G system.
Is your printer a wifi printer or hard wired only? If it's a wifi printer then you might want to look into third party apps like Print n Share or Print Central which allow a version of air printing to non-air print printers.
You may also want to look on the manufacturer's site. Maybe they have a fix for you.
If your printer isn't wifi, then you will need a router to get it on a wifi network to print to it. As far as I know, there is no support for the iPad to do wired printing. -
can I move all my photo that I can see on iPhoto from my Mac hardrive and put them on an external hard drive and still be able to see them as thumbnails in iPhoto? Thanks! The reason, I need to know if I can do this is b/c I am running out of HD space!sp
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

HI, I need your help. How can I delete all data, when I do not have the special security code, which I didn´t remember ? I also think, that I never create this code before. But I cannot put my settings back.
You must remember the code, if you can't then take the phone and proof of purchase to an Apple Store.

I am running version 10.5.8 and need to upgrade so that I can update to iTunes 10.7, what do I need to do?
Welcome to the Apple Support Communities
iTunes 10.7 requires Mac OS X 10.6.8. First, check if your computer is compatible > http://support.apple.com/kb/sp575 Then, call Apple to buy Snow Leopard > http://support.apple.com/kb/HE57 Finally, make a backup, insert the DVD and upgrade. When the upgrade ends, go to > Software Update and install the most recent version.
If you want, you can use Mountain Lion. See if your computer is supported > http://www.apple.com/osx/specs Finally, open App Store and purchase Mountain Lion. See if your programs are compatible > http://www.roaringapps.com -
I have an iphone 4, with ios 4.3.3. I want to update it but when I connect it to itunes it says that it is the latest version of the software. So I cannot update it, and I need it very bad. Can anyone help me?
What version of iTunes do you have installed? If you are trying to update to iOS 6 you need iTunes 10.7 or later.

I've been getting a pop-up that says Firefox needs to update, but it can't due to an error. I have checked and I have the current version (5.0.1). What's up with that?
Go to iTunes.com, then click on Download iTunes on the top right area, then on the next screen make sure it states iTunes 11.1 on the left side and email is not necessary then click on download now in the blue button. Issue should be resolved

On all of my SQL Server instances, I can find SQL server error logs that have the same 3 entries below, so while I already know it can, I need a Microsoft document that says "sqlservr.exe" can so I can convince the network guys to grant the service
account for SQL "Write servicePrincipalName: Allow" in AD.

Automatic SPN Registration
When an instance of the SQL Server Database Engine starts, SQL Server tries to register the SPN for the SQL Server service. When the instance is stopped, SQL Server tries to unregister the SPN. For a TCP/IP connection the SPN is registered in the format MSSQLSvc/<FQDN>:<tcpport>.Both
named instances and the default instance are registered as MSSQLSvc, relying on the <tcpport> value to differentiate the instances.

OS X Lion says that I need more space till I can download OS X Lion in the App Store, what should I do?
More hard drive space or more RAM? Lion will need at least 10gb of free space on the hard drive and a minimum of 2gb of RAM.
