Strain measurement with nı 9235
hello everyone
I am user of NI 9235 and my question is about measurement of strain gages. I attached the gages to material propertly and connect to nı9235 with embeded gage factor and ets. then I calibrate just with using button of calibration as attached pictures. I am not sure am I measure right data. I checked NI website, there is something mention about shunt calibration but it doesnt offered at NI9235.
Could anyone give some information about my problem?

Hi,
Here is a National Instruments white paper http://www.ni.com/tutorial/7130/en/ that walks you through taking a strain gauge measurement. This should assist you in setting up your measurememnt. What about the data makes you think it is not measuring correctly?
I have found some other resources that may prove helpful http://www.ni.com/white-paper/11488/en/
http://forums.ni.com/t5/Signal-Conditioning/shunt-calibration-NI-9235/m-p/2460276
Please let me know if these are helpful or if you are still having problems after this. Also it appears you are trying to use a DAQ Assisitant and from what I have read you cannot due a shunt calibration using DAQ assistant.

Load cells and non contact strain measurement
I am designing a bi-axial machine which meant for a fatigue test.
Could someone recommend me where to get a dynamic load cells and as well non-contact strain measurement?
Thanks.Hi Alvin788,
Do you presently use any hardware to measure these or are you enquiring as to what hardware/software you will need? Are you planning to use LabVIEW? The following three links talk about measuring Load Cells as well as Strain Gauges

Strain measurment and write to file with NI9237
Hopefully this lab view VI can help some of the novices like myself to acquire strain using the NI9237 and write to a file. The example VI available from NI "Cont Acq Strain Samples (with calibration)" is fine for sampling data and viewing on a chart, but you need to add your own elements if you want to logg data or write to a file.
Since aquistion is continuous, reading and writing data must be done at discrete intervals rather than continuously, or, you will end up with a very large file that can not be easily handles in excel. Also, data gets acquired in "packets" of several samples for each channel, so even if you put a write function within a case structre, as I have done ,and you don't convert the data you get that whole "packet" every time the comand writes to file. Again, you will end up with a lot more data points than you would like.
Though the top level VI is pretty simple, it took me some time and help from many folks for me to figure out what was going on. I thought I would share.
Thanks to Sandra T, Jarrod B, Kyle B, Marc A, Herbert E and Jesse O. for your help
Next goal is to acquire voltage from a different Daq card, convert to load and graph and write load vs. displacement.
hopefully the attached files are the correct method so the VI fuctions with its sub-VI's. If not let me know.

Strain measurement using 9237 and cDAQ 9172
I am trying to measure strain using a 9237 and cDAQ 9172.
The strain gage is connected to 9945 (Red wire to EX+, White to IN+ and Black to QTR terminal also tried connected the white and black to IN+ terminal).
The 9945 is connected to 9237 quarter bridge strain measurement module on a cDAQ 9172. I have two 9237 on the cDAQ 9172.
The device passes the test in MAX.
The problem is I cannot read the strain value.
Can anyone help me please?

Strain measure.vi 19 KBHi jujare,
In the VI you attached, you don't have the bridge configuration set up. The default is full bridge I, so if you have a quarter or half bridge wired up, that is one reason you could be getting bad data. I'd suggest you take a look at "Cont Acq Strain Samples(With Calibration)-NI 9237.VI" in the Example Finder. It shows the configuration for bridge type and has some handy wiring diagrams. You could also add controls to your vi to set the bridge configuration if you'd prefer.
If your strain gauge only has three wires, it's probably a half or quarter bridge. A full bridge needs at least four wires.
I hope this helps!

Strain measurements using labview and DL750 scopecorder
Hi
I want to use labview to do strain measurements using DL750 Yokogawa Scopecorder. I have installed the DL750 drivers and I can access them from labview, but I am a bit lost as to getting to communicate with the scopecorder, setting up measurements and so on. I am all new to strain measurements and to labview, is there a link or a tutorial that anyone would recommend I refer to?
Regards, tickleHi Tickle
It looks like the driver you are using is supported by a third party. I took a look at the driver you are using and it has a couple of examples included with it. I would recommend taking a look at these examples as they are normally a good starting point for communicating with your device. Has anyone else used this device in LabVIEW?

How to use external timebase for Two Edge Separation measurement with PCIe 6351
Hi
I am working with PCIe 6351 x series DAQ card.
counter measurements.
Here i need to measure the time/no edges between two edges. Falling to Raising of two signals.
I got the measurement with internal time base.
here i need to synchronize the measurements with external clock from the external setup.
so i need to use that external clock,timebase for the counters.
Any solution please..
Regards,
HariFirst, the VI you mention is NOT for STC timer/counters. Therefore, it won't work.
If you want to get the time interval between two edges, you want to use the Functions -> Data Acquisition -> Counter -> Count Events or Time VI. This will do the function you are looking for.

Unit of measure with language Key
Hello Guruz,
WHile creationd of purchase order, there is a check kept which compares the vendor communication language which gets updated in the Po header - Communucation tab with Db table T006A which holds the Unit of measurements with Language Key and pops up an error message.
It cheks the order unit in the PO, and the T006A whether the unit is maintained in the Language key as in the PO header - Communiction tab.
But while creating a unit of measurement in CUNI, we dont have the option to maintain the language key for the UOM.
In CUNI, it defaults the language key as EN in table T006A.
I need a prompt support from you guys on this issue. Please suggest how to go about with this?
Best Regards
Greg.Hello,
When i am trying to go for the language key in CUNI, it says that the said language is 'not available in server'. I guess it is checking whether the language patch is updated in the server.
But it doesn't sound logical to maintain all the unit of measurements in all the vendor languages. Suppose if we are having vendors with 75 communication languages and we are having 50 units os measurements, so does that mean that we have to maintain units of measurements 75 X 50 times ?
Kindly provide your inputs on the issue. We are facing lots of issues with this control kept in PO header checking for the T006A with the vendor communication language.
Regards

In the DAQmx 9.4 Readme the following is stated:
Samples Not Acquired on NI 660x or NI 6624 Devices When using pulse width, semi-period or two-edge separation buffered measurements with the NI 660x and NI 6624 on counters 0 and 1, some samples may not be acquired under certain circumstances.
Could anyone elaborate on this? I am particularly interested in knowing under what circumstances this problem arises for the 6602 PCI devices.
How should I understand 'NI 660x and NI 6624 on counters 0 and 1'. Is it only a problem on counter 0 and 1 for the 660x or does this only apply for the 6624 devices.
/molaAre there any NI Product Support Engineers out there who has an answer to this question and who are willing to share it with me?

Personal recruitment How to do new measure with function call Update IT4000
Hi out there and happy new year to forum,
i want to update to implement a recruitment measure (Transaction PB40). I did it already with batch input, but i guess it's much more comfortable to do with funtion module, bapi or calsses.
After choosing the measure, the infogroup will be processed. So i guess, i just have to use the corresponding function modules to update the infotypes in a given sequence. is this suggestion right?
What are these function modules? How to update f.e. IT4000? Does anyone has a coding snippet?
Is it HR_INFOTYPE_OPERATION?
In our Infogroup there are also customer specific infotypes f.e. 9***. Can I use the sap standard function modules for "own implemented" infotypes?
I also appreciate an abap oo pattern or any similar....
Best regards,

But I don't think that it's possible to hire an application completly with function modules (there is no PERNR in the beginning so I would keep the BIM).
The applicants already exists in system, i just want to implement a measure with exact one click!
Otherwise there is a BAPI for applicant_create.
I'm not very expierienced focussing the implementation in pa-recruiting. I'm really looking for a good documentation or anything like that f.e. sap press.

What are the alternatives to it. (I'm not looking forward to upgrade releases or using wd4a or webgui). we are on ecc 6.0 There is already a lot of z-coding in recruitment. We are also using an self implemented e-recruiting approach

Exporting set of measures with aliases into essbase cube
We were wandering if there is an easy way to import bunch of measures with aliases into Essbase cube rather then entering them one by one?
thank youSimplest way, would be to create a spreadsheet with the Measures and alias listed in column format.
You can organize them in Generation, Level or Parent-Child format.
Create a dimension load rule that maps the columns to properties in Essbase.
When you want to modify the Measures dimension layout, change the spreadsheet and rerun the load rule.

Error "CONVT_NO_NUMBER" while performing user measurement with USMM
Hi,
While running user measurement with USMM I am getting following run
time error.
To be specific - After preselections in USMM->system measurement->while
checking Green Check mark this error is screaming up.
Ae per Note - 1230640 :- You call transaction USMM and want to cancel
the user measurement using the cancel button (red 'X') on the dialog
box of the user measurement. However, the measurement continues and is
completed as if you had chosen the ok button (green check mark).
Above note is applied if the problem comes if we check red button
rather than green check mark.
Please suggest us the best way to procees.
ST22 details:-
Runtime Errors CONVT_NO_NUMBER
Exception CX_SY_CONVERSION_NO_NUMBER
Date and Time 09/16/2008 07:42:32
Short text
Unable to interpret " 1,410 " as a number.
What happened?
Error in the ABAP Application Program
The current ABAP program "RSUVM001" had to be terminated because
it has
come across a statement that unfortunately cannot be executed.
What can you do?
Note down which actions and inputs caused the error.
To process the problem further, contact you SAP system
administrator.
Using Transaction ST22 for ABAP Dump Analysis, you can look
at and manage termination messages, and you can also
keep them for a long time.
Error analysis
An exception occurred that is explained in detail below.
The exception, which is assigned to
class 'CX_SY_CONVERSION_NO_NUMBER', was not
caught and
therefore caused a runtime error.
How to correct the error
Whole numbers are represented in ABAP as a sequence of numbers,
possibly
with an algebraic sign.
The following are the possibilities for the representation of
floating
point numbers:
[mantissa]E[algebraic sign][exponent]
[whole number part].[fraction part]
For example, -12E+34, +12E-34, 12E34, 12.34
If the error occurred in your own ABAP program or in an SAP
program you modified, try to remove the error.
If the error occures in a non-modified SAP program, you may be able
to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the
following
keywords:
"CONVT_NO_NUMBER" "CX_SY_CONVERSION_NO_NUMBER"
"RSUVM001" or "RSUVM001"
"START-OF-SELECTION"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
Information on where terminated
Termination occurred in the ABAP program "RSUVM001" - in "START-OF-

Build the Bar chart from Cross Tab which have 3 measures with cell refr.cal
Hello Friends. I want to Build the Bar chart from Cross Tab which have 3 measures with Actual , Plan and Forecast
But Issue here is each cell is defferent like i have to do different calculation for each cell for actual, plan, forecast
like A = Jan act/Budget actual, Where as B = Feb Act/ Jan Budg+Febbdgt_March Budget
So now when I right click to say turn to Chart it is not generating the chart
Please help how to build bar chart since i do not have 1 key figure which i can drag and drop in view structure of chart so how to handle this
Jan, Feb, March, Aprl, May, June
Actual A B C D
Plan N M O P
Forecast
SONIYAHi Soniya,
It will be better if you can get these keyfigures calculated from the BEx with the help of structures in the BEx.
At the report level it will be complex to create these variables and also not sure whether going to work:
But you can try something like this:
A= If (L01 Moths="JAN") then Sum (Actual)/Sum (Bud) Else 0 similarly for other months.
Then you need to create one more variable (measure) which should be plotted on the chart as:
Final Act = If([L01 Month]="JAN") Then A ElseIf([L01 Month]="FEB") Then B ElseIf([L01 Month]="MAR") Then C
Final Plan= If([L01 Month]="JAN") Then N ElseIf([L01 Month]="FEB") Then M ElseIf([L01 Month]="MAR") Then O
similarly you have to create variables for Forecast, then finally you can plot final 3 variables in the graph.
Hope it helps you.

AC resistivity measurement with MyDAQ on TEC
Hello,
I would like to ask for advice: we would like to measure resisitivity of Peltier-elements. If we use DC method, because of the Seebeck-voltage of the element, we do not get the real resistivity value. The common method to use AC measurement in case of such devices. I would like to know, if it is possible to use a MyDAQ device for this task? As a first approach we do not need the best accuracy, this would be more as a "broken-element" test (there is usually a significant shift away from the nominal AC resistivity value stated by the manufacturer).
What would be the easiest way to carry out a simple measurement? What about if I use one analogue output of the MyDAQ lets say with 1kHz, and I drive the Peltier-element with this voltage AC source? And I connect a known resistor in series, and I measure the AC voltage drop on this. From this data, I could calculate the current, and the AC resistance of the Peltier-element? Of course I have to choose a resistor so the MyDAQ can drive the network.
what is your opinion, where to start?
Thanks!
Solved!
Go to Solution.Hello, thanks for the reply!
Actually I am just going to replace 60 Peltier elements in a "home-made" 15 years old heat exchanger (I expect to find some mice too ). This assembly has dropped performance (heat transfer power) and also I know that, a few years ago after a malfunction with the hot side cooling fans, this device was running for a certain time without forced cooling. What is quite bad in case of Peltier-elements. I have already bought 65 brand new Peltier-modules and after I get some heat conducting paste, I will replace them. And I will have 60 pieces of old Peltier modules, to play with them
Since I have this NI MyDAQ, I thought it would be fun (and would give also valuable information) to try to measure the old elements' AC resistivity. Since this task is not like I should do often, so for first, I would not like to go for more pro solutions, I will try the MyDAQ first.
I expect that some of the modules got structural degradation during the heat shock, and this may be measurable in a shifted AC resistance.
I would do the measurement with zero applied DC voltage. These modules are Melcor PT3-12-30L (discontinued product), the nominal module resistance is about 5 Ohm.
EDIT: and would you recommend a certain circuit to try? Shell I use a known resistor for current measurement via measuring the voltage on it? Or I could use a known AC current to drive the Peltier, and I would measure the resulted AC Voltage on it?
