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.

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.

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,

PXI 2527 & PXI 4071 -Questions about EMF considerations for high accuracy measurements and EMF calibration schemes?

Hi!
I need to perform an in-depth analysis of the overall system accuracy for a proposed system. I'm well underway using the extensive documentation in the start-menu National Instruments\NI-DMM\ and ..\NI-Switch\ Documenation folders...
While typing the question, I think I partially answered myself while cross-referencing NI documents... However a couple of questions remain:
If I connect a DMM to a 2 by X arranged switch/mux, each DMM probe will see twice the listed internal "Differential thermal EMF" at a typical value of 2.5uV and a max value of less than 12uV (per relay). So the total effect on the DMM uncertainty caused by the switch EMF would be 2*2.5uV = 5uV? Or should these be added as RSS: = sqrt(2.5^2+2.5^2) since you can not know if the two relays have the same emf?
Is there anything that can be done to characterize or account for this EMF (software cal, etc?)?
For example, assuming the following:
* Instruments and standards are powered on for several hours to allow thermal stability inside of the rack and enclosures
* temperature in room outside of rack is constant
Is there a reliable way of measureing/zeroing the effect of system emf? Could this be done by applying a high quality, low emf short at the point where the DUT would normally be located, followed by a series of long-aperture voltage average measurements at the lowest DMM range, where the end result (say (+)8.9....uV) could be taken as a system calibration constant accurate to the spec's of the DMM?
What would the accuracy of the 4071 DMM be, can I calculate it as follows, using 8.9uV +-700.16nV using 90 days and 8.9uV +- 700.16nV + 150nV due to "Additional noise error" assuming integration time of 1 (aperture) for ease of reading the chart, and a multiplier of 15 for the 100mV range. (Is this equivalent to averaging a reading of 1 aperture 100 times?)
So, given the above assumptions, would it be correct to say that I could characterize the system EMF to within 8.5uV+- [700.16nV (DMM cal data) + 0.025ppm*15 (RMS noise, assuming aperture time of 100*100ms = 10s)] = +-[700.16nV+37.5nV] = +- 737.66nV? Or should the ppm accuracy uncertainties be RSS as such: 8.5uV +- sqrt[700.16nV^2 + 37.5nV^2] = 8.5uV +-701.16nV??
As evident by my above line of thought, I am not at all sure how to properly sum the uncertainties (I think you always do RSS for uncertainties from different sources?) and more importantly, how to read and use the graph/table in the NI 4071 Specifications.pdf on page 3. What exactly does it entail to have an integration time larger than 1? Should I adjust the aperture time or would it be more accurate to just leave aperture at default (100ms for current range) and just average multiple readings, say average 10 to get a 10x aperture equivalent?
The below text includes what was going to be the post until I think I answered myself. I left it in as it is relevant to the problem above and includes what I hope to be correct statements. If you are tired of reading now, just stop, if you are bored, feel free to comment on the below section as well.
The problem I have is one of fully understanding part of this documenation. In particular, since a relay consists of (at least) 2 dissimilar metal junctions (as mentioned in the NI Switch help\Fundamentals\General Switching Considerations\Thermal EMF and Offset Voltage section) and because of the thermo-couple effect (Seebeck voltage), it seems that there would be an offset voltage generated inside each of the relays at the point of the junction. It refeers the "Thermocouple Measurements" section (in the same help document) for further details, but this is where my confusion starts to creep up.
In equation (1) it gives the expression for determining E_EMF which for my application is what I care about, I think (see below for details on my application).
What confuses me is this: If my goal is to, as accurately as possible, determine the overall uncertainty in a system consisting of a DMM and a Switch module, do I use the "Differential thermal EMF" as found in the switch data-sheet, or do I need to try and estimate temperatures in the switch and use the equation?
*MY answer to my own question:
By carefully re-reading the example in the thermocouple section of the switch, I realized that they calculate 2 EMF's, one for the internal switch, calculated as 2.5uV (given in the spec sheet of the switch as the typical value) and one for the actual thermocouple. I say actual, because I think my initial confusion stems from the fact that the documenation talks about the relay/switch junctions as thermocouples in one section, and then talks about an external "probe" thermocouple in the next and I got them confused.
As such, if I can ensure low temperatures inside the switch at the location of the junctions (by adequate ventilation and powering down latching relays), I should be able to use 2.5uV as my EMF from the switch module, or to be conservative, <12uV max (from data sheet of 2527 again).
I guess now I have a hard time believeing the 2.5uV typical value listed.. They say the junctions in the relays are typically an iron-nickel alloy against a copper-alloy. Well, those combinations are not explicitly listed in the documenation table for Seebeck coefficients, but even a very small value, like 0.3uV/C adds up to 7.5uV at 25degC. I'm thinking maybe the table values in the NI documentation reffers to the Seebeck values at 25C?

Seebeck EMV needs temperature gradients , in your relays you hopefully have low temperature gradients ... however in a switching contact you can have all kind diffusions and 'funny' effects, keeping them on same temperature is the best you can do.
Since you work with a multiplexer and with TCs, you need a good Cold junction ( for serious calibrations at 0°C ) and there is the good place for your short cut to measure the zero EMV. Another good test is loop the 'hot junction' back to the cold junction and observe the residual EMV. Touching (or heating/cooling) the TC loop gives another number for the uncertainty calculation: the inhomogeneous material of the TC itself..

PXI-6509 Error occurred at Reset Device

Greetings Everyone,
     I recently had three (3) PXI-6509's fail in one of my Test Stations. I tried to reset them in MAX and received the following message: "The device reset has failed. The error report from the device driver is as follows: Error -224903 occurred at Reset Device.". I also received "Error -50152". After that while I had the stores list up of all installed boards, the three (3) PXI-6509's removed themselves from the list.  I'm wondering what these error codes are telling me.  The pop up error dialogue box stated that the "Possible Reason(s): Internal Software Error occurred in Static_Digital_software". I'm also curious as to what this is relating to. I replaced all three (3) board from a NEW chassis that I'm bringing up for use and everything thing is fine. I tried plugging these failed boards into my other chassis and the computer will not even boot up. Thank you in advance for any information that you provide that will help me in understanding what may have caused this to happen. The system was working fine up to lunch time and after lunch is when the problems started.

Scott

Greetings Nick,
Here is the course of events that led up to the problem being described.
While testing UUT’s (Company Product): (PXI-1044 with PXI-8101(XP), GPIB Controller and various PXI cards installed)
Before Lunch everything was working well. It was after lunch that the following events took place.
a)     Test Sequence hung up during External Power Supply ramp up in which the D-I/O are used to switch relays inside the ITA (Interface Test Adaptor) to connect the DMM to the Power Supply that is in use at the particular time in the test sequence. This has happened a couple times before, but NO error ever happened and just re-booting the system cleared it.
b)     The next thing that was performed was shutting down TestStand and Labview.
c)     The next thing that was performed was executing “MAX”.
d)    Once in “MAX”, I normally try to RESET all of the PXI cards, which is usually successful, but not in this case. The error pop up came up with the two (2) different error codes (-224903 and -50152). Please explain what the “Static-Digital Software is?
e)     I shutdown “MAX” and Re-Booted the system.
f)      After Re-Boot completed, I executed “MAX” once again and clicked My System, Devices and Interfaces and PXI-1044 “Chassis 1”.
g)     I tried to reset the NI PXI-6509 “PXI1Slot7” and received the pop-up error as described.
h)    Upon clicking OK. The PXI1Slot7 and PXI1Slot8 removed themselves from the stores list of cards installed and the icon next to NI PXI-6509 “PXI1Slot9” changed from a little green board icon to a white board icon with a little red ‘x’ inside it.
i)      Next, I removed all three (3) PXI-6509 from a NEW chassis in a NEW TestStand that I planned to bring on line in a couple of weeks. I placed these boards into the TestStand that is failing and everything is working well once again. I ran some diagnostics and everything checks out OK.
j)      Next, I took the failing boards and placed them into the NEW chassis and the computer wouldn’t even boot up.
k)    Next I removed two (2) (PXI1Slot7 and PXI1Slot8) of the boards and tried to boot the computer and the computer booted up.
l)      I proceeded to execute “MAX” and check the stores list only to find that the board (PXI1Slot9) was not even in the category of the PXI-1044 Chassis1 but outside it and it also had the white icon with a little red ‘x’. It also affected the PXI-2575 in PXI1Slot10, which had a white icon and little red ‘x’. I removed the board from PXI1Slot9 and re-booted the system and PXI1Slot10 recovered with the normal green icon that is usually next to it.
What I need to understand is what “Static-Digital software” is and what the errors are telling me. The fact that three (3) NEW board installed into the chassis and function 100% tells me that there is something wrong with the three (3) boards that I removed from the chassis and that nothing else seems to be wrong with the chassis.
The fact that installing the three (3) boards into a NEW chassis and the computer not booting is something of concern. I’m trying to understand what could have caused this to happen in the first place so I can be prevented in the future.
Regards,
Scott
