Need to record the timestamp after activation...

Hello world! I am currently working on a .vi for some fire tests and I need help, try to understand this.

I have some smoke detectors in place. The tension extends from-10,4 V to 10.4 V and I use FieldPoint

When the voltage is at 10.4 the detector makes no noise, or, when the detector is less than 10,4 V turn off meaning that it detected smoke.

This decline occurs when I need to be able to record the timestamp and display it on the front panel. I thought of ways to do it, but I can't think about all the right ways.

If anyone has any suggestions that would be greatly appreciated.

Thank you

-Tanya

Hi tanyasue327,

Assuming you are using the FP Read VI in order to acquire the tension of your FieldPoint, you should be able to use the output from 'timestamp' read FP to get the time associated with the value being read. "" The 'timestamp' output will be in a double data type, but you can use the ' timestamp' feature in the functions ' programming ' Timiing palette to convert this DBL to a Time Stamp data type. ' ' Then you can view this at the front panel through a time stamp indicator and/or write to deposit using the screw found in the functions file IO ' programming ' palette file IO.

I hope this helps!

  • Satellite Pro A120: Need to update the BIOS after upgrade CPU

    Hello

    I have a Toshiba Satellite Pro A120 and I need to update the bios of a change in cpu cause.
    The laptop works very well, but for some reason any with the new processor fan runs always full.

    A lot, I searched but found nothing.
    The model number is PSAC1E-0QL04CG3 of ideas where I can find the bios?

    THX in advance,
    John

    Hello

    First of all: update BIOS doesn t help you.
    Why do you think that BIOS update should help reduce the activity of fan?

    I guess that your new processor is faster. Right?
    So it offers more performance and this leads to higher heat dissipation... so finally the CPU must be cooled and this can be done only if the cooling module would turn faster you agree with me?

    By the way: the update of the BIOS is on the page of the Toshiba UE driver. Since the satellite Pro A120 is very old series, you will need to search for drivers in area Archive (Type of product-> Archive)

  • need to record the data every second

    Hello

    So far so good with writing this simple .vi. I just have a problem. I need to record data every second. I use FieldPoint for thermocouple output signals. MAX is reading everything very well (I'm ambient recording, it is fondant between 80-83, so I put my stop for 83) and I can usually run the program for 5-10 seconds before my structure case is set to false and stops the .vi. When I open the file, I get data decimated. I tried a delay time and always the same. Not only she is decimated, but it does not record every second but between 5 to 10 seconds.

    How can I fix?

    .VI attached as well as the data element

    Thank you very much


  • HP Pavilion Notebook - 15-p199: need help with the installation and activation of 10 Windows after completely uninstalling Windows

    Hello HP assistants.

    I need help for a specific problem. My laptop came with an installation of Windows 8.1. Then I upgraded to 10 Windows when it became available. After a while, I decided to uninstall Windows completely (to wipe the hard drive) and install a Linux operating system.

    Now, I decided that I want to use some software that is not available on Linux and if I want to reinstall Windows 10. My problem is that Windows has completely disappeared in a form any. So now, I need to download Windows 10 from an official source (which I think can be done fairly easily from the official source of Microsoft, although if there is a better, HP official medium to do this then please recommend it) and then I need to activate Windows some how.

    As has been made clear, I have the right to use Windows 8.1 and 10 but I would need to download Windows 10 and turn it on. Is there a way to do this? I'm literally stuck without solution.

    Thanks in advance.

    Hello

    As long as the previous installation of Windows 10 had activated Ok after upgrade from 8.1, you can simply perform a new installation as described in the guide on the following link.  Note: On the activation screen, select "I don't have a product key" - Windows will activate automatically once installation is complete.

  • need to adjust the paper after each print

    I have that 7520 printer all in one for 2 months (new)

    After each impression I have to adjust the paper otherwise, I get the message: no paper

    Make sure your paper guides are tight against the edges of the paper, while paper is loaded in the tray.  There should be little nicks in the status bar to help you confirm that the guides are engaged in the correct position.

    Otherwise if you are referring to the feeder manual adjustment can be the best thing you can do.  AutoDocFeeders are normally not snap and often need to be messed with on many models of printer.  Sometimes a small building of habbit can solve a problem like this.  If this isn't the case, you can try to contact HP support since it is such a new printer.  However, unless you can prove there is a mechanical fault on the tray or feeder, it probably isn't something they can do.

    You don't have something with the message No paper well.  Same as if the guides are disabled the printer should recognize there's paper in a way or another.  Questions guide paper normally takes place at the inadequacy of the size rather than no paper error.

  • Error when try to save a file on the network after activating of Sync Center

    Hello world

    In society, we have here a folder on the network that is used and accessible in only 1 employee. This employee is a mobile profile, so, sometimes she works at home and at the office.

    To help in its work, we allow Sync Center, a partnership between the folder on the network, available in offline mode.

    But do not know why, whenever the change of user one sheet, Excel prints the error: "the xxx file is in use by the user xxx. Access denied. "

    This error started after that we have activated Sync Center.

    Anyone have an idea how I could fix this?

    Thanks in advance,

  • Illustrator CC 2015, need to draw the line after line with arrowhead already attached.

    CorelDesigner has an option where you just draw your line / lines and arrow is already added at the end of the line.  Not only that your arrow lines can have a color outside the line (which surround it). So if you make a technical with arrows pattern when placed on top the drawing there is white or what ever color you want outside the black line (what thickness you choose so) so it's easier to read the technical drawing. So, basically, it's not line against line. That's why you would put a little white around the line. He gives him the space to breathe and easier to read the technical drawing. In Illustrator, I find that I draw my line. Then hover over the line options palette, and then scroll down arrow heads and choose my arrow head. Then calculate the rest, make outside the line have a white that surrounds it. Thus, it can be placed on technical drawings. I find there are many steps I have to do when Corel has this feature built-in and you leave. I currently have a trial version of Corel. But... I already have Adobe Suite. I don't want to have to buy another program. But I also see that CorelDesigner is somehow more user-friendly for people who need to work with drawings technical line (writing). I understand that not every program offers the same tools. But I really need the speed of it because I work with a lot of technical CAD which are handed to me. If there is a way in Illustrator to draw my lines one after the other with the arrow head already attached? Then of course I need little white around it if its duplication on other technical lines.  It just seems like a lot of steps in Illustrator. I also understand I could draw a line w/arrow attached installer as I want. Then draw another line... use the eyedropper tool and click on the correct line and my other line with change. Once more... what a pain. I feel that I have to jump through hoops to get my final result. I hope so that there's something built in Illustrator, I did not know was there and just unnoticed.

    Yes, I was able to do, but this is delicate (buggy) to get there.

    Make sure that the two traits have identical points of arrows and line widths.

    After you have created your effect of offset on long-distance running, move the effect of shifting way somewhere else in the stack, and then put back where it was. This seems to be the only way to make it work. Weird.

  • First CS 4 can not record the clip after grupping

    Hello all,.

    I am now desperate and get help!

    I recorded an event on two DV cassettes. I read them with premiere CS4 on a hard drive as tape1.avi and tape2.avi.

    Now I try in vain to join them to one avi file, event.avi. I shot tape1.avi on the tape2.avi and cut window (behind tape1.avi).

    Then I grouped them (via the menu: clip/group).

    Then I tried to export (save the group file) via the Menu: file/export/media

    The Media Encoder is always started. But from here, I can't save the movie group!

    I can insert tape1.avi and tape2.avi in Media Encoder as a source, but they will be encoded again on different files and NOT a single file!

    So far I can't join then both bands for a movie!

    I made earlier than with adobe 7 pro first. And there is no problem.

    I have to finish because I promised to do before Christmas.

    After two weeks of not succeeding, I want to get help on the forum.

    Can someone help me?

  • I need to recover the Favorites after a Windows system restore.

    After doing a restore of windows on Windows 7 Pro, I have only the default bookmarks on my view your bookmarks"" button. In a backup of the system a few months ago, I got the files and folder Appdata Firefox Profiles. I tried to replace the new profiles of 'empty' to the former, but without success - I still have only the default bookmarks. Thanks in advance for your help.

    Note what to do a system restore will probably replace the profiles.ini file and all the profiles that are made after the date of restoration will not appear or be accessible through the Profile Manager.

    If profiles are still there, then you can use the Profile Manager to create a new profile and choose the location of an existing profile (choose a folder) of re - save profile.

  • Do I need to release the bitmap after use?

    If I create a new bitmap in a local function I must free from the output of the function or the OS automatically frees the bitmap image?

    If I do this the memory release after the release of the function?

    for (int i = 0; i)< 10;="">

    {

    Bitmap b = new Bitmap (...);

    }

    don't see any method in Bitmap to release.

    It is Java... once the reference is out of reach, or is null, the garbage collector releases (finally!) memory.
