• Acquisition of temperature on USB-Temp

  Hello

  I use a measurement computing USB-Temp in order to acquire the temperature with several sensors. I made the attached program for both sensors. The problem is: I must add I have a waveform for each sensor. Thus, the program will become quickly unreadable if I want seven or eight sensors.

  You know a way to fix? Perhaps with arrays...

  Sorry for the bad English

  Yes - instead of having a single waveform on your shift register, change this in a table of waveforms. You can then have your acquisition of data in a loop For the number of sensors you have.

  Here's a very simple example of how you can change your program:

  

  In addition, you should know because you generate a waveform, permanently if you run your program for a long time you will eventually run out of memory. You might want to consider looking at the architecture of producer/consumer so that your registration occurs while the data are acquired, instead of just at the end (it also means that you have given if your computer breaks down ).

• Second DAQ assistant in the power control system does not

  Hi all

  I need your help on this issue. I'm currently programming a VI for one command power supply for pool boiling experiments. The organizational structure of the VI program is attached.

  I use two assistants DAQ for steady-state acquisition and temperature unstable state data respectively. The first assistant DAQ (samples to read 5, 5 Hz rate) for the acquisition of works unstable state data well (see the attached image file first DAQ Assistant for acquisition of temperature unstable state). The second assistant DAQ (samples to read 12 k, 200 rate) for stationary data acquisition does not work (please see attachment image Second Assistant DAQ of steady-state temperature acquisition), showing only a series of data files size of 1 KB with no data on the inside. And indicators for steady-state data also revealed nothing.

  After a similar Q & A search in the forum, I tried to distribute different channels for 1 and DAQ assistant 2. However, the situation was almost the same.

  The material I used are chassis SCXI 1000 and SCXI 1303 Council to acquire thermal couple temperature data. Food was AMREL SPS200-50-K025. LabVIEW software is the 2014 version.

  I had just started to learn LabVIEW for only a month, and I know that the VI is a little messy. Hope you guys can also give me some advice on how to improve this VI.

  Have you looked at the error on the second daq assistant? You will see that a reserved resource error because you cannot use two different assistants. You do not mention the real DAQ hardware but there a clock unique convert. You can use only one assistant with a unique sampling frequency.

• compariing of data between iterations of the loop

  I am data acquisition of temperature with a Thermocouple NI 9213 drive and DAQ Assistant in a while loop.  I need to compare the temperature of a channel in an iteration of the loop with the temperature of the same string in the previous iteration.  The data collected in each iteration are delivered to a chart and a data storage file.  I know how to get the temperature from the data table in the current iteration, but don't know how to get the temperature of the previous iteration, except perhaps by reading the entire file in a table, determining the size of the table and query the last entries. This seems a bit ridiculous for each iteration of the loop and perhaps even embarrassing.   Any suggestions?

  Put the data in a record time difference. The left terminal of the shift register will have the data of the previous iteration.

• Show only cases selected on the front panel

  I write a biomedical code to a pulse duplicator. At present, there are three methods of acquisition of temperature, user input, powered by a signal from the probe to the acquisition of data and as an image. I gave users the possibility to choose the method they want however, on my front, I can see selectors of temperature for all three methods. Is there a way to only display a control to the method chosen by the user? Thank you

  There are several ways to address the issue.  The way I'd do it is the crux of property 'Visible '.

• temperature sensor with the acquisition of data usb-6009

  Greeting

  I want to use a sensor with usb-6009 to save the variation of body temperature about 15 minutes and then use these data in labview.

  If you please you can advise me with the best low-cost use and the way/circuit sensor connect it to the usb-6009.

  Hi ba7soun,

  If you can use with USB-6009 LM35 depends on the range of output voltage of the sensor. I understand that it requires a 5V supply with respect to the ground, which you can provide to the USB-6009 (more than 200 my should not come from the USB-6009).

  The maximum range of the USB-6009 is - 10V to + 10V, while the minimum range is - 1V to + 1V, also probably the output signal of the LM35 will be in this range. What you need to do is to compare the full range of the output signal with the range of the DAQ divided by 2exp (14) (because it is a 14 bit ADC) and ensure that the first is much more than the latter.

  Kind regards

• Laptop 15-AD129DS: installed Win7 on 15-AD129DS-lack of Driver: Acquisition of PC data and Signal Processing controller

  I recently installed Windows 7 on my laptop HP 15-AD129DS.  In the Device Manager miss me the driver for PC Data Acquisition and Signal Processing controller.   There is also an unknown device without driver right below in the section "other devices."

  I understand that this ususaly installed with drivers from the chipset.  But it didi not install in two different tests when installing Win7.  The Intel site seems to be of no assistance, or their driver utility.

  Can you lead me to the correct drivers?

  Thank you in advance,

• Acquisition of fast mode for 9214 with VB6

  Hello

  I have a VB6 application that acquires data from a device to measure temperature NI 9214. The unit has two modes of acquisition, large (default) precision and high speed. With the help of MAX I can see that these modes both work in a test Panel. However I can't see how to change the mode at high speed by program in VB6. I am generation and execution in VB6 in DevStudio 2008 on a virtual Windows XP machine (host is Windows 7) using 14.2 DAQmx. Also running the compiled executable directly on Windows 7 without problem. I just want to change the mode of fast sampling (up to 100 samples/s for a single channel), while the default precision is only 1 sample/s. looking at transients of the order of 0.01 s over a period of 2 minutes.

  Can anyone help with this?

  Kind regards

  Chris

  I found a solution that I posted a separate issue here. Thank you for all your help.

• with WSN Vernier temperature probe?

  Hello everyone. I have a hard time trying to get the sensor measures.

  I created the thread here: http://forums.ni.com/t5/LabVIEW/steinhart-hart-with-vernier-thermistor/m-p/2811150

  I think that now the formula is fine. So I realized, it could be that I chose the wrong node to work with probe thermistor based.

  So now I took node voltage/resistance NI WSN-3226. I don't know how to wire properly. EX0, AI0, and GND.

  Any help would be so awesome. Thank you

  Nicely,

  Poor

  Poor Hello,

  That's right - you get a voltage scale out, not a resistance value.  The manufacturer has provided additional information on the use of their probes with different here:

  Vernier: Can I use BTA Vernier sensors with another of A - to-D converter?

  http://www.Vernier.com/til/1952/?keyword=WRT-BTA

  In addition, it seems that there are already example screws provided making this conversion voltage - to-resistance to-probe.  I have found these Vernier website with terms like "ELVIS", "BTA-vehicles" and "reduced the tension.

  Vernier: Why is the temperature sensor read correctly with my NI ELVIS

  NI.com: Interfacing screw for Vernier biosensors (download of example provided at the top right)

  http://www.NI.com/example/31019/en/

  The VI "convert thermistor rdg" provided in the zip file seems to apply Ohm's law to determine the resistance of the thermistor of the acquired power, as you have noted.

  As a note - all this information was already available on the Web site with a minimum of research NOR and Vernier.  It's probably a good thing to consolidate this information in a single thread/place so that future users have access to it (that's why I'm a link everything), but by doing some research on your own or contact the manufacturer directly could have you up and running last week!  In addition, you must be sure that you understand your sensor and conditioning circuit before using the computer, do not understand what is happening is a good way to end up with measurement errors.

  In addition, you plan on leaving the WSN node attached to a Committee of ELVIS for the acquisition?

  Best regards

• Measure the voltage and the temperature simultaneously with PCI-6281

  Measure the voltage and the temperature at the same time at the same time. However, when I put the voltage and temperature in a loop, the acquisition of voltage is significantly delayed. When I put the voltage and temperature in two different loop, none of them works.  There is an example in aid of Labview as shown. This structure works fairly quickly? In addition, how a volgate get and temperature Analog DBL 1Chan 1Samp? I check the exported excel, the first column is 0, 1 the second column contains the value of the voltage, temperature value. I wonder how can I get these two values for each scan.

  ,

  Assuming that the DAQ cards can handle it, you can set an analog trigger for the channel of the tension.  Then you just X samples to get your 100us data value.  Keep the last sample.

• Acquisition of data ongoing and finished at the same time

  I have a reading program in the measurement of the temperature of thermalcouples and I currently have my system set up to take a finite number of samples.  During the acquisition, I am unable to see the data in the front panel and I want to put in place a way to visualize a graph of continuous for my data waveform is sampled so I can look to find errors.  Is there a good way to do this?

  You cannot view the data until it was acquired. It is the programming of the acquisition that is at fault. If you want to see it sooner, change the number of samples or the sampling frequency. With a graphic instead of a chart, you can simply change the number of samples and get a continuous display.
