Pxi-4071 Calibration

Hello,
Could you please let us know what the accuracy of the NI 4071 card will be if the Fluke 5700 calibrator is used instead of the Fluke 5720A?  For example, will the accuracy of the 7 ½  digit DMM be reduced to 5 ½ or 4 ½ digits if the Fluke 5700 is used for calibration?
Thanks
Dan

Hi Dan,
Using the 5700 in place of the 5720A will not affect the digits of resolution of the DMM.  However, because the 5700 is less accurate, the DMM may not be calibrated to its specified accuracy.  This will depend on where the calibrator accuracy falls within its range, and as such, cannot be determined absolutely.  Furthermore, the calibration may fail if the calibrator returns a ppm accuracy measurement outside of the range expected for the 5720.
Hope this helps.

  • PXI-4071 Calibration Date Update

    Is there a process to have the internal Calibration Date update [using the Cal Executive software] without running the adjustment-reverify routines?

    Hi sbdata,
    In general, unless an actual adjustment is performed, then the EEPROM is not written to and the calibration dates will remain the same. That said, if you open an external calibration and then close it, the calibrated date will be set to the current system time.

  • Pxi-4071 error on calibratio​n executive

    hi!
    i have this little problem with my NI calibration executive. The error says

    Can you guys help me on this? I am calibrating this NI DMM PXI-4071. Please see attached captured error.
    thanks.

    popoi,
    Thanks for posting on the NI forums. I have a couple questions for you that should help us get to the bottom of the problem. 
    What version of Calibration Executive are you using?  You should be able to find this by going to the Help Menu >> About Calibration Executive.
    What Equipment are you using to perform the calibration? There is a list of equipment here.
    Is this the only board that you are having difficulty calibrating with Calibration Executive? 
    Thanks!

  • How to acquire data through multiple channels in parallel using PXI 6070 E, PXI 4071 and LabVIEW?

    Hi,
    I am using NI LabVIEW, NI PXI 4071, and NI PXI 6070E to measure current through a variable resistance. Now, I am using one channel from SCB-68, but I want to add another channel in parallel so that I can have two resistors instead of one that I cam measure current through them.
    I have attached a Pdf file showing the setup for hardware in use and LabVIEW code also.
    Can anyone look at these files and give me guide lines or ideas that can help me resolving this issue, please.
    Thanks in advance.
    Best Regards,
    Shaheen.

    Your 4071 can only do one measurement at a time. Your DAQ cannot measure resistance either nor has it got any analogue inputs.
    However, you could use a multiplexer and multiplex your 4071 DMM. This wont give you simultaneous measurements but can acquire data one after the other, the speed is obviously dependent on the multiplexer you choose!
    Hope this helps.

  • Pxi-4071 constant current

    We use 4110 voltage source for current measurements on pxi-4071. We supply high-ohm (1.5 GigaOhm) resistor with few volts and measure current on 4071. All cables are shielded on ground of 4110 voltage source, but cables are about 5 meters long. What can be reason for constant current 5 nA at zero supply voltage? We don't know whether it software or hardware problem, and i already asked this question in LabView forum, autozero enabled in max doesn't help. Could be a reason bad shielding of ground in pxi-4110 voltage source

    I would focus on the hardware side initially. I would try the following steps.
    1) Make a current measurement on the 4071 with the inputs open to see if there is an offset. If so we should look into the DMM configuration.
    2) Connect your cabling and/or resistor without the 4110. If this adds the offset then it seems to be shielding/noise related.
    3) Connect the cabling and/or resistor to the 4110 with the output disabled. If this adds the offset then it could be ground related or also related to an offset in the 4110 output.

  • Setting Input Resistance on the PXI-4071

    The specifications for the PXI-4071 DMM indicate that the input resistance can be chosen as either 10 MOhm or 10 GOhm for the 100 mV, 1 V, and 10 V ranges. I see where this can be input on the instrument soft panel, but I have been unable to locate how to configure the input resistance when using the DMM in a VI. Suggestions?
    Thanks!

  • Pxi-4071 aux I/O how to output a control signal?

    HI, I am working on Pxi-4071 dmm card. I want to use aux I/O to out put a control signal for a relay on/off. Technically, I want to know how to do it with labview. Is any examples to start?
    Thanks
    Liming 

    Hello Liming,
    The DMM is capable of sending TTL triggers out on both the PXI_Trig lines and on the AUX connector on the front connection.  These signals are intended for controlling National Instruments switch modules and not powering/closing third party relays.
    If you're looking to control a National Instruments Switch there are example programs that demonstrate synchronous scanning with DMMs and Switches.  To locate these examples open LabVIEW and go to Help» Find Exampled...  Then Navigate to Hardware Input and Output» Modular Instruments» NI-Switch (Switches).
    If this isn't what you're looking to do, or if you have additional questions, please feel free to post back with more information.
    Have a great weekend!

  • Pxi-4071 shielding cable

    Hi, we use pxi-4071 on pxi-1033 for measurments and we connected shielded cables few meters long. We wrapped foil cables from the kit. After that we connected all the shields to the ground from the power supply. But we still remain interferences about 1nA and DC component 5nA. If anyone faced a similar problem, is it possible that we are too often measured current. Can you advise the shilded cables for multimeter in this case. 

    alyast wrote:
    Yes, we pretty sure in shielding, but we don't know why there is current constant component (5nA), while declared sensitivity - 0.1nA. Probably some bug with timing in LabView or something? I don't know what could be a reason for this behavior, and therefore ask noob questions.
    Why would you suspect the software when all the evidence points to an issue with the HARDWARE?  And if you're measuring in the nanoAmp region, you'd better be ABSOLUTLEY certain that your grounds are true and accurate.  Probably grounding to your power supply is not good enough.  Your power supply probably has to be grounded to a copper stake going - what is, it, six feet? - into the ground.

  • Pxi-4071 ranges

    Why is it so hard to find the ranges for the PXI-4071???????  I called National and they told me:
    The ranges that are possible to use are:
    +-.02
    +-.20
    +-2
    +-25
    +-250
    Yet when I open the soft front panel there is a range up to 1000 volts.  Where is this listed??  I need ranges for VDC, current dc and resistance ( opens...infinite)  I'm using the DMM drivers that ships w LV 8.6.
    Thanks

    All of the range specifications will be found in the PXI-4071 user guide and specifications document.
    If you search on ni.com for 4071 you will find the PXI-4071 product page.  Going to the specifications tab, and then clicking "detailed specifications" opens this document.  It contains all of the specifications and accuracy ratings of the device.
    NI 4071 Specifications (Multilingual)
    Page two specifies that for DC voltage the following are valid ranges:
    100mV
    1V
    10V
    100V
    1000V
    which also show up in the DMM soft front panel.
     For DC current, see page 4, which states
    1uA

  • Why would a PXI 4071 measuring resistance countinue to increase the measured valued for each measurement?

    I have  a PXI-4071 DMM and I am measuring a connection in the UUT. The value should be around 0.3 ohms. The program (exe) will run aprox. 20 times and during these 20 runs the measured value will progressively increase until is is over the limit of 1.5 ohms. If I shut down the exe and run the VI as a standalone (continuous loop), the resistance will gradually come down to 0.3 ohms. I then close LabView and restart my exe and the readings are normal (0.3) but then continue to increase until they are over 1.5 ohms. This process has been repeatable for the last week. I have attached the code I am running. What could be the problem with the DMM code?

    Uninitialized shift registers are a good thing to check for such a problem.  Do you see the same response with a soft panel and your DMM?  if not then it is in code.  Uninitialized shift registers would start at 0 (default is usually 0) and will retain their values from run to run.  Just a possibility dont have LV up right now so I cant check the code sorry,
