Neither daq usb 6008

Hello everyone...

IAM going to use it NI DAQ USB 6008 Board so to do this I have been programmed and build later... I would like to install in another computer for all this help drivers must tΘlΘcharger or?

Thank you

Only drivers of data acquisition is enough to install NI DAQ USB 6008.

  • DAQ USB-6008 will be able to power and record voltage for UMS T5 blood pressure at the same time?

    I would use my NI USB-6008 to power my blood pressure monitor UMS T5 ( but also to take readings of it, but I don't know if it's possible to do it properly. The power supply for the instrument can be as low as 5V, I can easily get the dedicated + 5V channel. I'm able to feed the instrument and connect it to an analog input on the 6008 and measure a voltage in differential mode. However, when you read the documentation of support for the instrument, I find the following:

    "Potential pitfalls of data acquisition: the pressure transducer is configured in a full Wheatstone bridge, the input voltage and mV signal output can be connected to the same reference (mass)." Therefore, the mV output signal can be measured using a differential voltage measurement. Therefore, do not make an asymmetric measure of pressure transducer mV output. "(

    My understanding is that the 6008 can take a differential measure if I attach the signal '+' and the signal "-" to the analog inputs of positive and negative terminals. However, it seems that all the ports of ground on the 6008 are grounded to the same reference, which would make my measure of invalid tension according to the above paragraph. So my real question is: if I try to record the voltage with one of the analog inputs on the 6008 in this way, is the valid measurement? Or I need to find a separate power supply, with a different reference field to ensure that the measure is accurate?

    The technical details of this device is very poor. The manual is not much better. Companies that want to sell scientific equipment should publish decent cards or get out of business.

    In section 3.4.3 General requirements the device is described as a "bridge not amplified circuit.  This information along with the impedance of the bridge should be in the specifications, because it is essential to apply the device under any circumstances other than the nominal behavior in 10.6 V.

    The answer to your question is:

    You can use it with the box USB-6008.  The 5 V supply will result in output voltages a little less than half (5/10.6) the voltage specified in nominal conditions. You can use the differential input mode on the box USB-6008.  The absolute input voltages will be approximately 2.5 V with the 5 V power supply. This voltage is in the range of the aircraft. The differences are likely to be less than 100 mV. The resolution of the USB-6008 on the + /-1 V is located about 0.5 mV so your resolution of pressure will be about 1% of full scale. The voltage input impedance and termination of the USB-6008 will present a few errors.  These can be in the order of 5 to 10%. I can't predict much better without the missing bridge impedance specification.  These errors should be relatively constant and systematic. A calibration of the whole system - sensor and together hardware DAQ should allow you to compensate for a large part of this error.


  • AO. MaxRate, AO. MinRate, AO. Properties of voltage. RNGs for hardware DAQ USB-6008


    in one of my report, I use the AO. Property of Voltage.Rngs to see if the selected DAQ card takes in charge the application voltage range. This works very well for my PCMCIA card as well as a PCI card. Now run the same VI with a USB-6008 device, this property gives all the return values. In addition, the report of AO.max.rate and AO.min.rate of the '0', the output is-200197 error properties. I use DAQmx as it is supposed to support the same functions for all DAQmx devices. Can someone please tell me what wrong here and how can I get around this?

    Best regards


    AO.min.rate and AO.max.rate are 0 and error-200197 back because the USB-6008 case supports the outputs analog hardware timed.  The description of error is "device does not support this property."  There is an entrance to the knowledge base for this question.

    By selecting 'Use Waveform' uses the synchronization of the sample clock.  The waveform data type specifies a delta t, which is used to set the sample clock frequency.  It is not supported on the box USB-6008.  You shouldn't set your calendar of sample type or explicitly assign the "On Demand".

    The DAQmx driver supports hundreds of different devices.  Not all combinations of properties are valid for all devices.

  • Pt100 (USB-6008) configuration problems


    I'm using the hardware DAQ USB-6008 (I know that's not accurate and all) and I use the Pt100 (QAP2010, click for plug technique).

    I connected it like this.

    Now in LabVIEW, these are the only options (DAQmx new task-> acquire->-> RTD temperature signals).

    If I choose for custom settings, I get these options (I don't know what variables that is).

    I use a small greenhouse where I need to measure the temperature and humidity and control environment (by using a fan to cool the cartridges to greenhouse and heat to heat).

    My goal is to read the temperature using a graph on the front panel.

    Can someone help me how configure/choose the right options? If you need more information I'll provide them as soon as possible!

    A quick search for RTD class B shows the precision and the coefficient. As Fan Ravens stressed resistance according to the temperature is plotted in the data sheet.  To control the temperature in greenhouse, a simple calculation of the slope of this graph is not good enough.

    Note that the USB-6008 case limited an active player on the outputs analog and it controls only the voltage. So you will need at least one external resistor and possibly and external power to excite the RTD.  These options that you have linked is not applicable to the USB-6008, which is a very simple device. You should perhaps simply to measure the voltage and calculate first resistance, then the temperature.


  • Want a ramp of output voltage over time and measure input 2 analog USB-6008


    I want to produce an analog voltage output signal that increases over time with a certain slope, which I'll send in a potentiostat and at the same time I want to read voltage and current (both are represented by a voltage signal) that I want to open a session and ultimately draw from each other. To do this, I have a DAQ USB-6008 system at my disposal.

    Creation of the analogue output with a linear ramp signal I was possible using a while loop and a delay time (see attachment). Important here is that I can put the slope of the linear ramp (for example, 10mV/s) and size level to make a smooth inclement. However when I want to measure an analog input signal he's going poorly.

    To reduce noise from the influences I want for example to measure 10 values for example within 0.1 second and he averaged (this gives reading should be equal or faster then the wrong caused by the slope and the linear ramp step size.) Example: a slope of 10 mV/s is set with a 10 step size. Each 0.1 s analog output signal amounts to 1 mV. Then I want to read the analog input in this 0.1 s 10 values)

    Because I use a timer to create the linear ramp and the analog input is in the same loop, the delay time also affects the analog input and I get an error every time. Separately, in different VI-programs (analog input and output) they work fine but not combined. I searched this forum to find a way to create the ramp in a different way, but because I'm not an experienced labview user I can't find another way.

    To book it now a bit more complicated I said I want to measure 2 input analog (one for the voltage of the potentiostat) signals and one for the current (also represented by a voltage signal) and they should be measured more quickly then the bad of the analog signal. I have not yet started with because I couldn't read on channel work.

    I hope someone can help me with this problem

    An array of index. You want to index the columns for a single channel.

  • How to connect my potentiometer (3 connections: wine, Vout & amp; common) to USB-6008

    Hi looking for help connect my knobs to my DAQ USB-6008. Essentially got some linear and chain of pots that will be connected to the fitting of the parts to give a linear movement of DC output voltage. Got DAQ USB-6008 DC output read and display in LABview.

    The pots have 3 electrical connections:

    1 input voltage

    2. output voltage

    3 common

    Entry and common connections are connected to my power supply DC leaving a single output voltage wire.

    1 should I connect DAQ in premium or CSR mode?

    2. as I have only a single output connection (as input and common are atttached to food) what can I connect to GND mode CSR (or the terminal for the differential mode - ve)? Can he remain unconnected?

    3. do I need to connect anything to the output of data acquisition channels? or data acquisition will read my entries and display them in LABVIEW?

    Excellent. Thanks for your reply. Think about it, as I have many pots to connect up to this unique DAQ so if I use the DAQ outputs to power pots, then I would be limited to two pots on the DAQ specification?

    If I use the other method and hang the pot common and input for external power supply-/ + terminal and the hook to the top of the pot then you suggest also, I need to pin 1 ground output to the AI1 on data acquisition. What is all the Earth? What do you suggest as a land? If I go down this road then allow me up to 8 pots on this data acquisition? (And I guess each other the GNDs would also need to be connected to each other input used?)

  • NEITHER USB-6008 connect to thermocuples and pressure sensors, control valve

    I am endevoring to build a gasification plant biomass for bench scale test process control plans. NEITHER USB-6008/6009 will be adapted for use as a data acquisition. I'll take RTDS, thermocouples and pressure sensors. I don't want to use industrial automation controllers.  It is also possible to use the channel of analog output for sending signals to a control valve position (using sufficient current/voltage between the two drivers).

    (1) OK.  I just wanted to be sure that you were aware of the potential dangers.

    (2) an RTD is a resistance that has small changes in resistance per degree of temperature change. To measure that you have need of a current source and a sufficient resolution in order to detect small changes.  At 25 degrees C a typical RTD is 109,73 ohms and resistance ohms 0.38 per degree changes.  If you had 1 my crossing this RTD voltage through it would be 109,7 mV and the voltage change of 0.38 mV by degree.

    The resolution of the 6008 on the most sensitive range is 0.49 mV > 1 degree.  The accuracy of the 6008 is 1.5 mV typical.

    For a Type K thermocouple, voltage at 25 degrees is 1.407 mV and change by degree is 39 µV.  Millivolt solving half of the 6008 translates into about 12 degrees.

    If you need a source of excitement for RTD and a kind of amplification for thermocouples and RTD before she would make any sense to try to use USB-6008.

    (3) I have not used anything except LabVIEW with DAQ devices and drivers.  I think DAQmx can be used with MATLAB and other languages.

    (4) the 6008 is the low range made by NOR. You will need to go to a more expensive camera or add signals conditioning circuits.  Talk to your representative OR assistance in the choice of a suitable device.


  • NOR-traditional DAQ will work with a USB-6008?

    Hi guys,.

    I have ordered a USB-6008 and I would use it with the NOR-DAQ traditional 7.4.4 instead of MX. Is this supported?

    Thank you


    LV 8.6

    LV 8.01

    LV 7.1

    TS 4.1


    No, traditional DAQ isn't USB compatible, 6008.

    You can use DAQmx base instead, but I wouldn't recommend it.

    hope this helps,

  • USB 6008 DAQ scaling


    I use a USB-6008 to read signals from analog voltage to a device I built. The task is configured with a single reading finished with a range of + -10 volts. There is no scaling in the task or in the block diagram, but when I acquire data in a PDM file and view it, I get a load of PieceWisePolynomial scaling properties. I have attached the TDMS spectator to this post.

    Does anyone know where it comes from because I can't explain it.

    Thank you

    The data goes back as an unsigned integer between 0 and 32 k of the ADC on the 6008.

    The scale is to convert this unsignedInt to floating point value between-10 and 10.

    What is the impedance of your voltage divider?  The input of the USB-6008 impedance is not very high. If the impedance of the partition is large, it could cause the effect you see.


  • NEITHER USB 6008

    Dear all!

    I'm looking for help on the NI USB-6008 case. I'm putting in place 4 K thermocouples using this USB-6008 4-channels. I made an express VI in the Labview 8.5 and I have installed all these 4 channels in this VI. The VI is attached for your review!  Come to the problem! I get strange readings of these 4 channels even if I have no thermocouple connected to the terminals with respect to this USB-6008. Please help me and explain what is happening? Why am I getting these strange temperature readings while there is no connected thermocouple?

    Greetings to all!
