Slow measure ca in application C++ with DMM-4065


The Soft Front Panel does not use niDMM_Read(), it uses niDMM_FetchMultiPoint(). The niDMM_ReadStatus() see you traced simply checks the size of the back of the measure and the status of the acquisition (running, completed late, finished without delay, etc.). It does not take a measure, that's why she returned much faster than FetchMultiPoint().

There are no special tricks to increase the speed of the Soft Front Panel. What you see tracks are real calls makes the driver.

If you are currently using niDMM_Read() in a loop, you should be able to increase your speed of measurement more further by opting to use niDMM_FetchMultiPoint() instead. Read() calls Initiate() and Abort(), which when you are able as fast as you are, can take up to a large percentage of your measurement time internally.

That said, the speed of your application will be highly dependent on your configuration - if you turn down your opening time, your quality will be reduced and depending on how accurate and precise, you need your measures, which may be unacceptable

  • A measure of speed high speed with encoder in quadrature and NI 9401 on cDaq

    Greetings,

    We use an encoder in quadrature with 360 pulses/turn on the tracks (track A and B) and no trace of Z to measure motor speed at startup. Data acquisition, we use a NI 9401 in 9178 cDaq chassis and a pc with LabVIEW. The problem is that the start-up period is relatively short (less than 1 second), during which we measure speed as precisely as possible. The speed range is from 0 to 10000 RPM.

    What type of measurement method that you would recommend.

    Here are a few methods that we have already tried:

    -Measure with DAQmx CIFreq--> high frequency with 2 counters: speed measurement, but with a very big mistake (+ 166 RPM).

    -CIFreq DAQmx--> wide range with 2 counters: good speed data but more slow measurement,

    -CICntEdges DAQmx (counting separated the two lanes, speed conversion): very incoherent speed data.

    Thanks in advance for your help.

    I would definitely say a 4, the measure of a low freq called option with 1 meter.  (Frankly, I've never been

    fond of this name because it is useful for freqs much higher than what I expect most people think "low freq".)   This

    is the method that I almost * always * use for frequency of counter measures.  It works really well to capture transitional

    variations in speed.

    10000 rpm and 360 cycles/rev, you are looking at a maximum frequency of 60 kHz.  The frequency measurement mode 1 meter

    There will be 80 MHz internal clock by encoder cycle edges, then you will get more than 1000 strokes per measure.  The point

    that means only 1 number of quantization errors, you can expect<>

    Further, you can average overall, say, 10 samples to you give even better accuracy and you could still be a data capture

    rate significantly higher than the probable bandwidth of your mechanical system.  (The average would just clean the jitter and noise and would not

    Hide answer true mechanical characteristics).

    Hello, hope someone can help with my MacBook Pro sluggish.

    I'm in OS X Yosemite 10.10.3 version and tried to upgrade to El Capitan 10.10.5 on a Macbook Pro 13inc mid-2012.  He said it has already downloaded twice, but when I open the software it is still sitting at 10.10.3 without modification, download seems to take a lot of time - been sitting for about 6 hours.

    Now I trying to open the photos app but get the following error coming - the application built with PhotoLibraryPrivate version 215.65.00 but works with version 209.52.00.

    Any advice on what are the options for my new photos app! Have you tried different time machine backups and the computer does not like it either

    Upgrade to El Captain OS X 10.11.2 which includes Photo 1.3

    I have no idea of what you see on "El Capitan 10.10.5" as far as I know is not exiat

  • Applications installed with device drivers OR

    I bought a few applications that have been written entirely in LabVIEW that also use data acquisition OR PXI cards.  Before the installation, I installed the drivers of devices OR newer.  I discovered that more than 70 applications installed with the drivers.  Where can I learn what do each of these applications?  I need this information because, in order for me to install device drivers OR on my networked computers, I need to know what my local network vulnerabilities could be introduced with these applications.  If anyone can help?  I enclose a list of executables (*.exe) installed in the C:\Program NIUninstaller Instruments\ folder only.

  • MsiError 1627 then install application created with labview 2009

    Hello

    I tried to install an application created with labview 2009, I have this fatal error ' MsiError 1627: 1: 2727 2: UsFile.

    Executable works fine while the installer does not work!

    UsFile is a Lvclass. I don't understand why I have this message.

    Thank you very much.

    Hi thanks for the reply,

    I don't delete the installation program. It has not been disabled or corrupted MSI.

    Problem is in the source file: ProgramFilesFolder was not also identical to my request. So I refreshed that (the folder UsFile appeared not in ProgramFilesFolde)

    Now it works!

    Thank you very much Bye

    Hi all

    We improve our 11.1.1.3 to 11.1.2.2 HFM application using hfm copy utility.

    We also have run utility upgrade schema hfm and then save it with shared services.

    but we can see the error in hfm as system messages

    HsvDatasource for application ABC with a process ID of 5424 on server Hhfserver could not start!

    Server: HIBTV-HYP1T with ID 0 has been removed from the list.

    Unspecified error

    It seems that HsvDatasource hfm application does not start even in the Task Manager

    have idea about it

    Hello

    That's how oracle has solved this problem.

    We had rules of /HFM of calc scripts in calculation for this HFM application manager.

    If oracle has asked us to remove references by running as a result of the SQL on the schema from table binaryfiles HFM hfm

    delete ABC_binaryfiles where label like '% CalcRules % ';

    After execution of this statement, we could open our HFM application successfully without any problem!

    Kind regards
