• Specification OR ELVIS II + DMM

  Hello

  Recently, I use NI ELVIS II + for the characterization of the sensor due to the measurement of the resistance to 100Mohm.

  However, I found the spec said 100Mohm measurement can be done by using max test 5V voltage source and current source internal 500 nA? Using Ohm's law, 10Mohm has proved to be the maximum extent?

  

  Kind regards

  Hello

  DMM NI ELVIS II has a permanent entry of 11 MOhm resistance. For the measurement of the resistance, the device under test (DUT) is assumed to be in parallel with this 11 MOhm. The ASE resistance is calculated from this nonlinear relationship by measuring the test whereas calibrated current excitation voltage and parallel resistance.

  For example, a 10 MOhm DUT measured in the interval of MOhm 100 with a current excitation nA 500 would show all (11 M: 10 M) * nA 500 ~ = 2.6 V.

  With a 100 MOhm DUT, the test voltage would be of about (11 M: 100 M) * nA 500 ~ = 4.95 V... right against the limit of 5 V.

  Enjoying a beautiful, the test voltage is (11 M) * nA 500 ~ = 5.5 V that is larger that the 5 V limit and is detectable in the 'OPEN' in the software.

  NI ELVIS II DMM design was obtained from an other DMM with the input resistance is selectable (11 MOhm or > 10 GOhm). In this case, the excitement of nA 500 could be used in conjunction with the 10 GOhm input impedance to give 10 MOhm resistance measuring range. Since the resistance of the DMM NI ELVIS II entry is fixed, there is a separate offer 10 MOhm.

  I hope this is useful,

• Elvis II + 64 bit driver will not download

  I have a Council Elvis II + and tried to install the drivers on your laptop Thinkpad Windows 7 64-bit. I already have 32-bit labview installed, but the jury is not find the drivers by itself and when I try to select the drivers for her to use, he accepts it or work.

  I am very confused as to the cause. Is it possible for me to get a specifically 64-bit driver download?

  A mistake, that I had was that when I downloaded the drivers, he said that it was incompatible with the 32-bit driver.

  Hi SamuelDelattre,

  I do not know what link you are using however the link below is fully supported on a 64-bit Windows 7 with 32-bit LabVIEW. You can post a screenshot of the error you get? It might be useful to uninstall all the drivers ELVIS you currently one do a fresh install.

• Error-9314 has produced Elvis comm - check elvis connection.vi

  Could someone help me with this? I have windows 7 64 bit. I have installed 64-bit and 32-bit labview. I have NEITHER myDAQ connected to my laptop via USB. The CD that came with the kit disappeared, so I was download each disc that I could install and updated.

  Here's what I get

  All I'm trying to do, is get the myDAQ to act as a digital multimeter to measure resistance using the wires supplied with the kit myDAQ.

  I have to install a battery or something in the myDAQ? I saw a picture of the battery has a triple, but don't see any on the myDAQ battery compartment. There is a battery 9V on the myProtoBoard property, but it does not help the issue.

  Thank you

  Hi Jason,

  It seems that you have installed the legacy version of the NI ELVIS driver, which only supports the NI ELVIS device. Use an NI ELVIS II / II + or one NOR myDAQ and use the DMM feature, you will need the NI ELVISmx driver. The latest version is NI ELVISmx 4.5, which supports versions of LabVIEW 2010-2013. If you have another version of LabVIEW, let me know and I can direct you to the correct version of NI ELVISmx.

• Power of Board on NI Elvis II prototyping does not illuminate

  After connecting a different prototyping to the Elvis, the power of the prototyping card has stopped working on the Elvis. Even when I reconnect the prototyping card NOR Elvis series to the Elvis he will not work. The LED in the upper right corner of the Board of Directors indicating same light until it sends power to the Board of Directors. Although the Active USB LED still lights up when it is turned on.

  I have checked and replaced fuse for Elvis and it still does not work. I also tried different prototyping cards, but the problem seems to be in Elvis himself.

  Any ideas as to what could cause this problem and how I might go about fixing it?

  It's working now. We opened the plate to try and test it, and during the process, it restarts and works now. Thank you all for the replies!

• Problem with launichnig of used VI NI ELVIS

  Hello, I have a hard time with the launch of the virtual instruments using NI ELVIS - problem in that the program don't miss to find "NI ELVIS DIO - close.vi", "NI ELVIS DIO - write.vi", "NI ELVIS - initialize.vi" s ' Please tell - where can I get listed VI? And the 2nd problem is that in the instruments OR ELVIS (DMM for example) - in the "Peripheral" field only empty string is available. So with that, the measuring instruments is unavaileble. How can I fix it fails and specified in this field ELVIS I?

  Please pay attention to my sentence, Margaret.

  1. I use NEITHER ELVIS I have couple with car NI DAQ 6251

  2. I use the NI ELVIS v4.10 with NI DAQ software v8.9

  3. the rear switch is turn on and power light lights ELVIS brilliantly.

  So, I use NI ELVIS to ELVIS II software, but I suggest that this software is also suitable for NEITHER ELVIS I. And I don't see the difference between a device specifeing name in the menu software configire for NI ELVIS I and select the device in the "device" field in the menu of the instrument. Is this good idea to install a software for NI ELVIS I (old version)?

  Also, when I use NI DAQ in LabVIEW as a simple virtual instrument some NI DAQ and NI ELVIS works properly, and problems only appear when I try to use Software v4.10 NI ELVIS instruments...

  And also - how or where I can "NI ELVIS DIO - close.vi", "NI ELVIS DIO - write.vi", "NI ELVIS - initialize.vi" for LabVIEW?

• How to use I2C with ELVIS

  I try to connect the sensor ultrasonic NXT to ELVIS, for this I need to use I2C. I was wondering how I can use I2C with ELVIS?

  The Council of ELVIS doesn't I2C communication. Our scanners high speed and the NOR-8451 are the only materials that support the I2C Protocol.

• Running the latest Labview 2010 on new computers (Windows 7) but who have the older/more older material NI ELVIS

  We are running the latest Labview 2010 on new computers (Windows 7) but have more older/more old material NI ELVIS (NI ELVIS I?).

  LabVIEW works very well and the device drivers are installed.

  What NI ELVIS software move us?

  The latest version indicates that it is for ELVIS II and III hardware.

  Thank you

  Hi Tom,

• Elvis II: FGEN, very fragmented signals low level

  We recently purchased some Elvis II platforms: very beautiful products.

  In any case, we have a problem with ANY when the amplitude is very small (about 10 ~ 30mVpp) signal (osserved on the scope) is really fragmented.

  We use as input AI1 (FGEN <->at the entrance to the quadrupole which is GROUND referenced) ed AI0 (output of the quadrupole, always referenced to GROUND)

  We have connected the two pins of AI (-) STILL common then to EARTH, while FGEN transits through the prototype Board.

  FGEN share the same GND AI?

  Where we are wrong?

  Thanks in advance

  Hi Parisi,

  I think that do you things in the right way. However, it is possible to see a bit of noise (which you see in your screenshot) for a lot of factor. In addition, Elvis II is a very useful and powerful but is not designed to operate small voltage.

  You saw the same behavior you acquire a significant voltage signal (more than 1 VP)

• ELVIS + D - SUB

  Hello

  I have a simple question, are the pins d - SUB or not connected to any i/o lines?

  Heart I need to implement RS-232 communication, so I can use the DSUB directly or I must use D0<0...7> and connect it to the Sub - d?

  Thank you.

  Hello

  If you use the jury of prototypes with ELVIS, you must connect the pins d - SUB (1 to 9) in the /output of entry digital with sons of prototyping.
  There is no internal connection.
  Then, you will be able to communicate with the d - SUB read/write input/output digital.

• Use NI ELVIS II Oscilloscope and Agilent Oscilloscope at the same time

  Hello

  I designed a circuit in the 3D NI ELVIS of Multisim view and I want to use the oscilloscope NI ELVIS II and Algilent oscilloscope show students how to work with the two oscilloscope but the problem is when I use both of them not of them works. Judgment of NI ELVIS II Oscilloscope running and the other a desnt show nothing but as soon as I delete the Agilent one OR ELVIS II Oscilloscope starts showing traces. I would like to know is possible to implement both at the same time

  On my computer the two instruments work, but very slow

  Here's a tip: disable ELVISmx instruments that you do not use (each active instrument consumes resources systems):

  • Stop the simulation.
  • Go in simulate > parameters of Simulation NI ELVIS.
  • Uncheck the instruments that you do not use.
  • Click OK.

  When an ELVISmx instrument is disabled, a small red 'X' appears next to the upper right of the icon of the instrument on the schema.

  Let me know how it works.

• measurement of frequency for ELVIS

  I use Elvis and I want to measure the frequency of an analog input signal.
  I use this program I found in a manual form OR.

  I'm using LABVIEW 8.0.

  The problem is that the program is not read the frequency. No mather how often I try to read always indicates r = the same thing.

  I have attacheted the program below.

  Americanu22,

  A couple of things that you will want to consider:

  1. to ensure the frequency information is correct, you must be 2 sampling * [highest frequency in your Signal].

  2. you can consider an ongoing acquisition with a configuration like this (' this example can be found in Help "" example Finder under material input and output "analog measures DAQmx'):

  Good luck!

• The jury of ELVIS will work with LabVIEW Student Edition 2010

  Hello

  This question was asked in the forums of LabVIEW, but no solution has been found. I have a windows 7 x 64 machine with LabVIEW 2010 Student Edition. When I try to install ELVIS 3.0.5 traditional software I get the following (no error code) message: "this Setup program requires the LabVIEW 8.5 development system or later to be present on this computer. Development system LabVIEW Base in any version of LabVIEW is not supported. Please install LabVIEW and then rerun setup of NI ELVIS. »

  I also installed the DAQ software for PCI DAQ board. I do not have access to a 32 bit machine and do not know how to get my board work (no ELVIS II) ELVIS. I have provided a screen shot of the message during the installation of the software of ELVIS.

  .

  Hey dduong16,

  Thank you very much for taking the time to provide additional information. After talking with several experts about your system, we concluded that this error is the result of an incompatibility between 3.0.5 Elvis and LabVIEW 2010 64-bit. Even the latest drivers of Elvis are not yet supported by 64-bit LabVIEW: see notes in support of the operating system on the Readme Elvismx 4.2.3

  To solve your problem, you will need to uninstall the 64-bit version of LabVIEW and install a 32-bit version. If you are a student, you should be able to get this version of your computer (it will work fine with your Windows 7 64-bit OS - it will install on 32-bit OS emulated inherent in your system). If you are not a student, please send me a personal message, and we will be working with an account representative to get you the necessary version.

  I apologize for the inconvenience, this made you and appreciate your patience. We have updated the Elvis 3.0.5 Readme to reflect this incompatibility (the change may not appear yet, because it takes time to propagate through our system), and I'm trying to create a Base of knowledge on the subject article to help future users who encounter this error.

  If there is anything else that I can help you, please you after return. Thank you!

• NI Elvis and Multisim interactive without labview

  If a circuit is implemented and tested with the help of Elvis, the results of an output displayed in Multisim and Labview?  If I want to change my Multisim simulation to match the output of the circuit set up as Elvis, is possible in real time?      I know that TINA can do with their hardware/software.     Thank you

  jweaver-

  You can display the measurements in Multisim and LabVIEW.  With NI ELVIS, you can use 12 instruments of autonomous software by installing the driver (FGEN, Noculars, DMM, ect).  The instruments are built using LabVIEW.  You can access these same instruments in Multisim environment and compare the Multisim circuit simulation commensurate with live material in real time.  I included a tutorial describing how to do it using equipment OR myDAQ.  The steps are the same for NI ELVIS.

  If you want to create a custom beyond the 12 instruments application, you can program the instruments in the LabVIEW programming environment.

• For our ELVIS II units, I'm getting an error-200220. What is the problem with these units when they worked a month ago?

  On several computer stations, we receive the message error-200220 when you select any instrument on the Launcher of the Instrument when you press the run option. This message has not been deleted once the computer has restarted and the power of the bike box. What's wrong?

  I don't find this error code in the product documentation.

  On the screenshot you attached, it seems that there is no devices specified on the front panel, which means that the error you see is correct, the device identifier is invalid.  Are there available devices in control of the aircraft?  Your ELVIS II appears as connected in measurement and Automation Explorer (MAX)?
