• How to change the input range (DAQ assistant) with a digital command?

  Hello everyone

  I am currently working with the NI USB-6218 acquisition card.

  In order to acquire a signal, I would like to be able to choose the input range of the DAQ with a digital command Wizard (and not opening the window of DAQ assistant) (as 'number of sample' and section 'rate'...)

  Is this possible and if so, how?

  Thank you very much in advance for your answers!

  You can't with the DAQ Assistant so just click on and select "generate the Code of OR-DAQmx. You can edit the Subvi who performs the installation.

• R series analog input range

  Hi all

  I'm starting my first app using a card of RIO for the analog input and power (two PCI-7833).

  My previous experience with DAQ systems was on PC so I'm especially familiar with DAQmx. It is my understanding that DAQmx is not really being used on these boards, there is no DAQmx tasks to play with.

  So, my question is this: How can I dynamically set the range of the signal of the analog inputs so that I get the best possible resolution?

  What I want to say in DAQmx if I know that the input signal is only 1 V pk to pk I can put this beforehand in the task.

  Thank you!

  OK, a little further digging shows the input range is set to +/-10V, is this correct?

• PCI-6110 to change analog input range

  The analog signal I want to measure is 24 volts and the maximum PCI 6110 is Volt.However 42, analog inputs that appear in the device under device NOR-DAQ traditional (old) configuration is 10 volts (single selection). I'm using LabView 7.1, DAQmx 8.6 and there is no function for allowed me to modify and change the analog device input range (Please find the print screen of the attachment). Can I know how can I change the analog inputs range?

  I think that's what you're looking for:

  S how to set up a data acquisition card series for the entry level so it does not Clip?

  You must set up an appropriate gain so that the other ranges of voltage is displayed.

  In addition, you can post on the forum instead of Labview data acquisition in the future, because the chances are that you will get better/faster responses there

  Good luck!

• Change the height of an Input Range Slider (Skinning)?

  Is it possible to change the displayed height of an Input Range Slider? Not the height of the item itself, but the actual bar.
  
  I found the list of different skin options on the [ADF Rich Client Demo site | http://jdevadf.oracle.com/adf-richclient-demo/faces/components/skinningKeys/inputRangeSlider.jspx], but I couldn't not (explicitly) an option to specify the height.
  
  I tried to add the height to af. inputRangeSlider::content however which only affects the size of the bounding box of the element. Are there other count options that might not be on this list? Or is it just not possible?
  
  Thanks in advance!

• The NI 9215 input signal voltage

  Hi all

  I tried to test NI 9215 BNC in MAX. And the acquisition of data took place without input signal.

  The voltage for all 4 channels, I read is about 10.4 Volt.

  Is this fair? I thought, the voltage should be 0 without input signal.

  Best regards

  GL

  If you leave the open entry, it will tend to float to one of the rails.  From my experience, it's almost always the top, so the 10.4 volts.

  If you short-circuit the input, you'll get certainly 0 volt.  You will probably get 0 or nearby yew, you put a resistance across the entrance.

• PCI input range of NOR

  Dear Sir

  I read in user mannual of NI PCI-6281, that he has paid minimum entry-100 mv to 100 mv. So if I select this range reslution will be 0.2/262144 = - 122 dB. Now if I have to measure the signal of-160 dB then how can I measure?

  I read somewhere that NI PCI has gain adjustable fromm 1 to 10000 and by adjusting that win, I could measure the signal-160 dB. Can you please guide me where I can date the gain? I check in the DAQ Assistant, but did not.

  Thank you.

  Concerning

  Tronoh

  The gain is set automatically when you specify the minimum and maximum. The range of your card is found in the specifications. A different device might have a lower minimum range but to suggest that the ICP has in general a lower range is all just ridiculous. Everything you read 'somewhere' should refer to another card. If you need a higher resolution, you need a different device.

• PCIe-634 x independent analog input ranges

  I have a PCIe-6343 and I want to be able to power different ranges on different channels of entry at the same time, more precisely with the customer is able to select ranges for each channel when necessary.  Ideally I want to I could have HERE with-10 0 - 10, AI 1 to 04:55, AI 2 with-1 to 1 and AI 3 with - to 0.250 0.250.  Anyone know if this is possible?  I tried to put a table for the minimum and maximum values, and it did not work.

  The only active channels are the ones you decide to put in the array. The only beaches that are enabled are the ones you decide to place in their bays. How you decide to complete the paintings belongs to you. I suggest a front screen where you are able to select one channel and the beach, then click to add to a list.

• Acquisition of data NOR-9205 Assistant set up range of input voltage

  How to configure the module NI9205 to use the +/-200mV input range.

  I use a custom scale, and it seems that I can not get an accurate reading.  I use a shunt current of 100 Ma (max 10A).  So I custom balance setting to have 100 x + b.  The current flowing in the device is 2 amps and I get a reading of 12-13 amps after custom scale.  Now I think the module is configured to sample for the entrance of 10V and I get an error of resolution.

  Hi therbert

  Since your custom scale is 100 x, to work on the beach of +/-200 mV to your NI 9205 module you must configure your input signal of maximum and minimum range for +/-20 respectively.

  According to the equation: Range.max * scale.slope = 200mV * 100 = 20V

  This will automatically configure to the scope of the module +/-200 mV to verify you can access the channel DAQmx property node and look for the analog input > General Properties > advanced > Range property, this will let you know in what range is the functioning of the device.

• Configure the input voltage range

  I use an NI USB-6221 with SignalExpress 3.0 card.

  The Spec for the 6221 map specifies 4 analog input ranges of +/-10V, 5, 1, & 0.2.

  My question, how is the range of input voltage on the map on one of the beaches specified?

  The closest thing I can find in SignalExpress is step 'DAQmx aquire', looking at the tab "configuration" of "Configuring the stage." There is a group called 'settings', there are areas of maximum and minimum input Signal, but context-sensitive help indicates that it is expected for the channel after the scaling values.

  I also looked into MAX, but I see no way for me to directly configure one of these ranges.

  Can someone explain how this works?

  Mike

  You look at the right thing. When you specify the min and max, the DAQmx driver and then automatically selects the best range of this signal. For example, the Council supports + /. 1 + /-1, at ± 5 and ± varies from 10 volts and a jury of 12 bits. If you enter max/min to + /-2, the jury will be set to the +/-5 volt range. Your resolution is then 10 (oscillation of the total voltage) volts divided by 4096 (2 * 12).

  If you were using LabVIEW, you can get the actual voltage selected range by using channel properties DAQmx AI. Rng.High and I. Rng.Low. If you specify a min and max that is less than the amplitude of the real signal is greater than the actual scale used, then you cut your input signal. DAQmx does not have an autoscale. Take a look at Page 4-2 in the Manual of the M series.

• Input signal is set to +/-0 .5V when it is connected to an analog input

  Hello

  I have a difficulty connect an analog source to the analog inputs of my acquisition of data (USB-6215). The analog signal is output operational amplifier through a 10 k resistor. I wore the signal out of the amplifiers is 10V peak, I then move the probe across the 10 k (the analog input terminal) and the signal is clipped to +/-0 .5V. If I reduce the amplitude of the signals of source less than 0, 5V Ridge there is no clipping.

  Maybe the analog input range the value +/-0 .5V which is causing this as a form of protection? I don't have a LabView to try to change the input range as I do just the wiring.

  Analog source is connected to him HAVE 0 and the ground of the analog source is connected to the GND AI.

  Thanks in advance.

  Joel-

  Have you tried to read the data through the data acquisition device?  If that's what you try to do, I'm curious about what we read.

  If you have measurement and Automation Explorer, go ahead and open a Panel to test for the unit and see what are your tensions.

  Let us know how it goes.

• analog input quantified

  Hello

  The data entry in LabVIEW by my USB-1208LS is accurate, but the analog input voltage values are quantified (there are only a few repeating values: 0,691 0.696 0,701 0.696 0,701 0,691 0,691 0,691, etc..). I am able the tensions of four photocells, propelled by the + 5V of USB-1208LS. Each cell is measured in a different channel using the differential input mode. Is it possible to fix the quantification of data?

  I don't know if it's a problem of LabVIEW, but attached is my diagram, in the cases where I'm not seized the tension properly.

  Thank you in advance.

  On the input range, the resolution of this device is about 5 +/-10 V mV, which is exactly what you see. The resolution is established by calculating the length of the total voltage range (20 V) and dividing by the number of steps or bins the A/D converter on this beach (2 ^ 12 = 4096). Yes, resolution = 20/4096 = 4.883 mV.

  To get the best resolution, you will need to use a smaller range (if your signal wil fits into a smaller range) or get a DAQ hardware with a higher resolution, for example a 16-bit converter, or 24-bit.

• In Labview 8.5, what happens if the input signal exceeds the scope of the signal defined by the DAQ Assistant?

  Hi all

  This should be a pretty simple question, but I can't seem to find the answer online and currently do not have the functionality to test this:

  I'm using LabVIEW 8.5 and have a VI that imports data from sensor through the DAQ Assistant. In the configuration tab, there is a range of signal input. What happens if my sensor exceeds this range? I get a warning? The default value is the maximum (or minimum)? I was interested in writing a code to display an error that I approach the limits of this range, but did not know if I also need to include code to display an error if the scope is exceeded as well.

  Thanks for the help,

  Tristan

  Hello, Tristan,.

  The behavior depends on the selected range and the device you are using.

  If you are using a device with a single input range is valid, we will use this range, even if you set a smaller minimum and maximum in the DAQ Assistant.  So, if your device only supports ±10V and you set the range to ±8V, you will still continue to get valid data after your top sensor 8V until what you approach 10V.  When you reach the limit of the extent of your device, the output will be 'rail', and simply return the maximum value until the signal is less than the maximum value again.

  Note: A device that is nominally ±10V usually has a go-around (such as ±10.2V) which are usually specced in the manual.

  However, if you use a device with several ranges of entry then things become more complex.

  NOR-DAQmx player will choose the smallest range that entirely covers the interval you choose.  For example, suppose that your device supports the following input range: ±0.2V, ±1, ±5V, ±10V and you choose 0V - 3V as the range in the DAQ assistant.  The NOR-DAQmx driver will focus on the input range and the list of the entry lines that your hardware supports and choose the smallest encompassing the entire range that you set.  This would be the ±5V, because this is the only beach that contains up to 3V.  Thus, all between ±5V input signal is returned and none outside this range will be 'rail' to the maximum or minimum value.

  We do this because using small beaches make more efficient use of the resolution of the ADC.  So, we try to use the most effective range based on what you ask without picking up a range that will make you miss data.

  Let me know if I can clarify it more.

• cDAQ-9181 + OR 9206: how to set the nominal range in LV

  Hello

  The specifications of the NI 9206 voltage module HAVE indicates that 4 (± 200 mV, ± 1 V, ± 5 V and ±10 V) programmable input ranges are available.

  The question is, how programmatically choose one of these ranges of in LabVIEW. I can't find a VI DAQmx node or property to do so.

  I'm looking for something similar to this, but with a cDAQ and PC.

  Thank you!

  The channel create DAQmx is used. You set the min and max and the driver will automatically select the real scale

• USB 6211 measuring range

  Hello

  I am curious about the measuring range of the DAQ USB 6211 box, and specifically how it is defined. In the manual for the device, an array of ranges of input supported is listed here http://www.ni.com/pdf/manuals/371932f.pdf containing the same information to be redone in full UNAMA in article 4-3; However, in MAX and Labview configuration entry is completely arbitrary! In other words, I can whatever values I want to finish up and ranges of minimum entry as long as they are not superior to 10V. Of course, I'm a bit skeptical that this variable configuration continuously on the software side causes sensitive side material changes. My questions are: should I stay an of these ranges of measurement? Happening actually on the material side when I put the input range to something other than one of the recommended ranges of entry? If I put +/-250 mV, is still sensitive in the output?

  Thank you for your time and help,

  Matthew Berwind

  The DAQmx driver accept all values in the range, but will check against the specified material and gives an error, a warning, or just simply adapt to a next higher range that match.

  So after a configuration, you can use the property node or the DAQmx vi to read the chosen effective range by the driver.
