Can I measure temperature using 6013 & 68LPR?

Hello, from hardware I've got Multifunction DAQ (6013) and Therminal Block (68LPR). From software I've got VI Logger (1.0.1) and NI-DAQ (6.9.3). Using this, can I measure temperature with K-Type therminals? (Everything is installed and ready to go)
If yes, how can I connect K-Type therminal to thermal block? Are there any instructions on how to use VI Logger to perform similar task to this one?
Also what I want is, the temperature that has been read (for an hour, every 5mins) to be written in a file. Is it possible to write to a file using VI Logger?
Thank you!
Regards Slav.

How can i measure temperature using thermocouple using labview?

please list out the procedures to be followed to measure temperature using thermocouple using labview.

Do a search in the LabVIEW Example Finder (Help->Find Examples). There are a ton of simple Analog Input examples in there using DAQmx. One you might be most interested is "Thermocouple - Continuous Input.vi".

Problems on measuring temperature using thermocouples connected to SCB-68 terminal block

I have problems on measuring temperature using thermocouples connected to SCB-68 terminal block.The thermocouples were connected to the differential channel 1 and a return path for the instrumentation amplifier bias currents and a 4 Hz low pass filter were both developed. But the readings were floating and jumped randomly between 0 and 200 Deg Cel abnormally.The CJC on the terminal block was disabled and a new one was developed by myself. However, the readings for the CJC were accurate and quite stable. So what is the reason for the floating of thermocouple readings? Did I miss anything that I need to do? Thanks.

Are your TCs floating or grounded? Basically, if your TCs are mounted to a metal test article and the object is grounded to earth, then, the TCs are grounded -- and very likely contaminated with ground loops. You will need to reference the TC inputs accordingly. These ground loops will cause the TC data readings to float - recall that TC readings are in the millivolt level. It does not take much of a ground loop to ruin a TC measurement.
Also, try this... first, set the filter to 10KHz and sample for a few seconds at 20 KHz (take 32768 data points). Now subtract the mean value from the trace and perform an FFT on the data. Look for the dominant frequency. Is it 60 Hz or some multiple? If yes, the likely cause is a ground reference problem.

Simple VI to measure Temperature using Agilent 34901A

I am trying to measure/record temperatures using Agilent 34901A and 34970A. I have all the T type TCs connected. I am not familiar with Agilent drivers so if anyone can provide some guidance. I just need simple VI. I am familiar with typical DAQ Assist VI and acquire signal from NI Hardware but no experience with Agilent. I got the drivers for Agilent but it seems much more complex than I need it to be.

I have been messing with a variation of Agilent drivers for the last couple of days. Labview's built in Visa drivers don't handle Agilent stuff quite correctly, and so you need to install their driver version (with the Agilent IO Libraries Suite). There is lots of documentation showing you how to configure LabVEW to work with their Visa drivers. Once you get that taken care of, I'm sure there are sample programs you can model off of. For example, try here:
http://www.home.agilent.com/agilent/editorial.jspx?cc=US&lc=eng&ckey=1838058&nid=-11143.0.00&id=1838...
And don't forget to apply the thermocouple coeffecients in to your program if you scan the voltages directly

Can not measure temperature and voltage simultaneously

I am a beginner with labview. I want to measre temperature and voltage simultaneously. When I run
the VI, I can get temperature or voltage, but not togther. I attach my VI, please give me suggestion on
how to make it work. 3X

Since I don't know your exact configuration I will make some basic assumptions based on how it appears that you have configured the DAQ Assistant Express VIs.
Assumptions:
1. You have only one DAQ board in your system.
2. You want to scan continously
3. You want to acquire 3 temperature channels at a rate of 1000S/s and take 100 readings at a time
4. You want to acquire 2 voltage channels at a rate of 1000S/s and take 1000 readings at a time.
Based on this configuration your first problem is that you have configured the DAQ board to acquire continously in the first call to the DAQ Assistant (your first frame of the sequence structure). This ties up all the analog acquisition resources without releasing them. When you make your second call to the DAQ Assistant (your second frame of the sequence structure) you are creating a conflict because the DAQ board is already busy running your first request. At this point you are probably receiving an error but you might not see this since you are not doing error checking in your code. This is also why you are only getting one set of data. Next iteration of the while loop the first call to the DAQ Assistance reconfigures the board and executes again and so the cycle repeats itself.
I don't have a DAQ board installed so I can't confirm with certainty if I am correct but you can do this by simply changing the DAQ Assistant properties. In the 'Task Timing' tab change from 'Acquire Continuosly' to 'Acquire N Samples'.
Assuming this works all you have done is confirmed that my assumptions are correct and technically your program should work. So now some programming advice.
It's ok to scan all channels at once even though they might not be of the same type so go ahead and configure all your channels in one DAQ Assistant call and get rid of the sequence structure. Decide on one set of parameters for Scan Rate and Samples to Read, in your case I doubt this will be a problem. Since you are performing the same analysis on all channels you don't need to parse your data simply pass the 'data' from your DAQ Assistant into a single 'Amplitude and Level Measurements' Express VI. You will now have a single array with all your Mean values based on the order the channels are configured. If you want to plot the data in different graphs all you need to do is parse your channels using the 'Split Signals' or 'Select Signals' Express VI.
Hope this makes some sense.

How to use labView to measure temperature using a thermistor

I'm trying to create a labView that will give a temperature reading based on a circuit using a thermistor. Any ideas on the VI or how to construct the circuit would be helpful!

Well, you need to generate a voltage. You also need a way to read that voltage. Do you have a meter, or a DAQ device?

How do I use traditional NI-DAQ to find a temperature using a thermocouple?

I have seen examples using scxi modules and NI-DAQmx programming to find temperature using a thermocouple. For my application, I do not have a scxi module and my programming is in traditional NI-DAQ. I tried copy and pasting a NI-DAQmx application into my program and it did not work due to the traditional and mx conflict. My question now is how can I measure temperature using a thermocouple with Traditional NI-DAQ programming on a PCI6025E? Thank you.

Measuring temperature using thermocouple and SCB-68 box

I used thermocouple and SCB-68 box to measure temperature. But the readings were fluctuating around the expected value. So I removed the thermocouple and short-circuited the differential input channels. As expected, the voltage reading was not zero and also fluctuating. It seems that there was something wrong with the SCB-68 box. What might lead to this and how to solve this problem? Thanks.

The problem could be either the SCB-68 or the DAQ card you are using to make the measurement. You should first ensure that the DIP switches (S1 - S5) of your SCB-68 are in the correct position for your application. Please refer to the SCB-68 User Manual for more information on this subject.

http://digital.ni.com/manuals.nsf/websearch/74C86ADEF0E4813F86256C84007CB3AB?OpenDocument&node=1180_US
What do you mean by fluctuating? Full swings from 10V to 10V? Hitting one rail? Close to 0V but looks like noise in mV or uV? If your fluctuation is very slight, for example off by a few millivolts, than you could be picking up noise or your board could need to be calibrated. You can read more about accuracy and
calibration from the following web page:

If you have an E-Series Card you may be interested in running our Online E-Series Diagnostic Utility. This utility takes about 3 minutes to run, will perform a calibration, and will generate a report of anything that may be wrong with your board.

Can NI myDAQ ai0 and ai1 be connected directly with thermocouples to measure temperature???

Hi,
I am trying to use myDAQ to realize both temperature measurement and digital output.
By reading this page I have learned that how I can create a task for temperature measurement using thermocouple with a certain NI device.
http://www.ni.com/white-paper/14338/en/
What I found to be really interesting is that when I create a task for myDAQ temperature measurement using a thermocouple when my NI myDAQ is connected with my PC, two AI ports ai0 and ai1 both appears in the create task window!!
I never found any information from NI myDAQ manual that "AI0 and AI1" can be connected directly with a thermocouple to measure temperature without using additional conditioning system. But this window suggests that myDAQ can be used in this way, is it?
I am still trying to do it this way, and I'll post some results here again.
I would be really appreciate if anyone could confirm or disprove my guess. Thank you.

Can I measure AC voltage using FP-AI-102? I want to measure in the range of 0-120 VAC

Can I measure AC voltage using FP-AI-102? I want to measure in the range of 0-120 VAC

Hello Luis,
The update rate on the AI-102 module is 360Hz, which means that you can only accurately acquire waveforms with frequencies below 180Hz.
FieldPoint wasn't made for high speed measurements, so you will have to make sure that you are able to acquire the waveform you want to with the hardware that you have.
If you want to know how you would do the acquisition, I urge you to take a look at the LabVIEW shipping examples.
Help»Find Examples... and browse to Hardware Input and Output»FieldPoint»Analog IO
As for writing to the file, you can take a look at examples under Fundamentals»File Input and Output. You can use the functions included in the Functions Palette under Programming»File I/O.
I hope that this helps!

Can i measure moving distance using after effects?

can i measure moving distance using after effects?

I don't know what you mean. If you mean take measurements like you can in Photoshop and relating them to the real world then the answer is not easily. No Effect I know of allows you to do that. If you mean measuring the distance in pixels a layer moves on any axis, yes you can measure that and display the result using an expression by either referring to a valueAtTime of a keyframe or a layer marker. For a layer marker for example showing the X distance a layer moves starting at first layer marker you would add this expression to the source text of a blank text layer. The moving layer would be named "target."
t = thisComp.layer("target");
mp = t.marker.key(1).time;
ip = t.position.valueAtTime(mp);
np = t.position[0] - ip[0];
Math.round(np)
If the layer is moving left to right and the marker is in the middle of the layer then the numbers will be negative until the marker is reached, zero at the marker, then positive after the marker is past.

How can i measure a voltage with the digital i/o port on my nudrive using labview?

I am using a 4SX-411 nu drive to control my stepper motor. I need to measure an input voltage at the digital I/O port of the nudrive. How can I program LabVIEW to do that?
Thanks

Hello Raven24,
Thank you for contacting National Instruments. NUDrive 4SX-411 is a value motion drive and you can connect to it using any of the ValueMotion boards. When using a ValueMotion NUDrive with steppers you have I/O ports 1-4 available for general purpose use, I/O ports 5-8 are reserved for axis inhibit output signals. Refer to section 4-7 of the ValueMotion Hardware User Manual linked below, for information about the jumper settings.
ValueMotion Hardware User Manual:
http://digital.ni.com/manuals.nsf/websearch/6CF7A54E0BDEA1388625665F0054FFDF?OpenDocument&node=132090_US
Once you have setup the jumpers appropriately, you can use the VIs found on the ValueMotion I/O & Limits pallet for configuring and using the I/O channels. Search for "I/O" in the attached help file for more information about these VIs. I hope this helps you out. Have a great day!

How can I measure selected area of pixels using photoshop elements 12?

how can I measure selected area of pixels using photoshop elements 12?

Show the 'information' panel F8).
In the middle horizontal section, select 'pixels' on the left drop-down menu.
Use the rectangular marquee tool to select your area: the dimensions in pixels of the rectangle is shown under 'dimensions' on the right.
I think there are other ways to measure a line segment, but you could use the above measure by adjusting the rectangular marquee tools to both extremities of the segment,
- use the move tool to rotate the rectangle so that the diagonal measuring the segment is horizontal,
- move the rectangle to the left, and check validate, which creates another rectangle including the first one
- read the pixel dimension (L:) in the info panel like above.

What is the min pulse width that can be measured using a 32-bit conter?

what is the min pulse width that can be measured using a 32-bit conter?
and also by chnaging the referenced Clock, can we measure as min as 10ns pulse width?

You could measure a 40ns pulse, but not with a great degree of accuracy. Here's a good document on how counter pulse width measurements are handled:
http://zone.ni.com/devzone/conceptd.nsf/webmain/7C77FB9EDC17C3C386256802007B8AB3
With a 40 ns pulse, you'd have 3 counts per pulse so your uncertainty is pretty high (33%). Another way to look at it would be that you would read either 3 counts or 4 counts which would be values of 37.5ns (3*12.5ns) or 50ns depending on where the rising edges fall. So you wouldn't be able to tell the difference between a 40ns pulse and a 42ns pulse, but you would between a 40ns and a 100ns.
Hope this helps,
