Using 6052E card to measure current

Hi,
I am very new to implementing hardware with basic measurement in labview.
I have a PXI6052E card.
I believe it has AO of -+10 V.
Does anyone know where or how I can find examples of how to make a basic multimeter with the card?
I want to provide -10V and +10V with 0.04A to a circuit and the read the current for that circuit.
Is it possible?
Thanks
Best regards,
Krispiekream

Krispiekream,
Do you understand basic circuit theory?
The AO is a (weak) approximation to a voltage source.  That means that it tries to produce the specified output voltage, regardless of the current bing drawn by the external circuit. The actual circuit cannot produce more than 5 mA without either deviating from the specified output voltage or possibly being damaged.  The actual amount of current drawn is determined by Ohm's law and the external resistance. If the output is 10 V and the external resistance is 500000 ohms, then the current will be 10 uA.
However, as has been pointed out, the device has no method to measure its output current.  One way you could measure the current through the external device would be to connect a resistor in series between the AO pin and the external device.  Using an input of the AI part of the device, measure the voltage at the junction of the series resistor and the external device.  The difference between the voltage programmed at the AO and the voltage measured divided by the resistance of the series resistor is the current flowing.  From Ohm's law you can then determine the resistance of your external device. Make the series resistor larger than 2000 ohms and you cna be sure that a short circuit in the external device will not draw more than the speicified 5 mA from the AO.

  • How to measure current and resistance if i only have DAQ using VB 6 and Measurement Studio

    I want to do a remote lab for basic electronic lab. One of the task is to measure current and resistance. How to do it if I only have DAQ card and using Visual Basic 6 and Measurement Studio. Can anyone give me a clue.

    If your DAQ device is supported by DAQmx, you can use it with VB6. Here's how: NI-DAQmx Support in Visual Basic 6.0.

  • How do I remove a credit/debit card from my account? I ask because I currently have a VISA gift/debit card with 50 dollars on it, but the money has run out so I want to usea new card. Also, there is no 'None' check option for payment type on my account.

    Depending on how you created your account, "None" may or may not be an option. I believe it has something to do with whether the account was made through an App Store request or the regular iTunes Store. For example, my account allows no card but my father's doesn't allow there to be no card.
    To change the card, go to your account settings and change the information to your new card, and hit save.

  • Hi I have an iTunes account with my uk debit card but am currently in Australia, can I buy and use an iTunes/app store gift card in AU$ or am I only allowed to acces the store in gbp£ ?

    I had the same error when trying to update my apps on my ipod touch. I tried to input my security code numerous times to no avail. I also made sure my billing address was the same as what my bank had on file. To fix the issue I went into iTunes, logged onto the iTunes store, went to account settings and reviewed my recent purchases. Turned out that I had made a recent purchase and didn't have enough money left on my credit card to pay for it at the time. I paid off the credit card, and then input my security code once more and now it works fine. I've heard that some debit or pay as you go credit cards require a minimum balance, so make sure you have at least that amount in your account.

  • To measure current in DAQ should we use rms value or DC avereage value

    to measure current in DAQ should we use rms value or DC avereage value

    i am taking measurement for single phase or 3 phase voltage and current and display it on front panel voltage measurement is valid but doinh with current measurement i suffer some problem should i take dc avg value or rms value for measurement 
    when i take dc average value it give result as i want but doing with rms valur it give wrong result according to my circuit sitution. As, we know in ac case rms value is used for measurement but it give wrong result so guide me in this regard 
    THANK YOU

  • How can I measure Total Harmonic Distortion using sound card?

    Dear LabView users,
    I am a new LabView user. I want to measure Total Harmonic Distortion and other power quality related parameters using sound card as a part of my mini project. It will be helpful for me if anyone can send related NI files, manuals, block diagram etc. 
    Thanking you in advance.
    Best Regards,

    Which Labview version do you have. Some functions that you need are installed with the Full Development System. Owning Palette: Waveform Measurements VIs
    Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

  • How to measure current and voltage and rpm with daq device

    i am measuring current and voltage and am wondering should i use shunt resistors or current sensors hall effect sensors. i have a pci 6221 and a scc-68 breakout box. what specifications or size should the shunt resistor/current sensor be or should i use another device to measure the currrent and voltage. do i need any other safety device between the resistors, current sensors and the scc-68 breakout box when measuring the current and voltage. will the daq card pci 6221 pick up a signal from the resistor. what terminals should the wires from the resistors and current sensors be connected to in the scc-68. i am using a proximity switch to measure rpm of a motor. should the proximity switch be 2 or 3wire connection. should it have an analog or digital connection and is a power supply required to power the proximity switch and should it have an npn or pnp connection

    hello,
     i was going to use a 20amp 50mv, or a 20amp 100mv current shunt and connect wires directly into the AI input terminals of the scc-68 from the current shunt would these be suitable. would current shunts such as these be suitable to use http://uk.farnell.com/elc/sh10020/shunt-sh10020-20a-100mv-1-class/dp/1319576 or http://uk.farnell.com/datel/3020-01098-0/shunt-50mv-20a/dp/1339338
    is it ok to use either a current shunt or should a hall effect sensor be used  such as this http://ie.farnell.com/honeywell-s-c/csla2cd/sensor-hall-effect/dp/1082269 . which of them would be more accurate or are both of them fairly accurate.
    when i am measuring voltage can i connect two resistors between the positive and negative of the wires going to the battery and connect two wires from either side of the resistor directly into the analog inputs of the scc-68 and measure the 12-15 volts directly would the pci6221 and scc-68 be able to measure the voltage drop across the resistor.
    i wanted to measure rpm also does it matter whether the proximity switch has 2 or 3 wires and should it have an analog or digital/frequency output for cponnecting to the scc-68

    I need help, I use my phone for everything enclusive to work. I appreciate if you can help. I'm from Brazil. My name and giullia.

    Did you purchase this device from Apple or an authorized reseller? It sounds as if you had a device that was jailbroken/hacked to operate on your carrier. Upon updating the iOS, it is now locked back to the original carrier the device was locked to.
    Only the carrier the device is locked to can authorize an unlock. You will need to make contact with that carrier and see if they provide unlocking services, and if they do, if you qualify for an unlock. Otherwise, you are out of luck. One that carrier can take care of the unlocking.

  • Using a 9205 to measure RPM

    I have not used labview in over 10 years but now have an application that requires but I am more then rusty. I am trying to measure RPM using a 9205 module and I am sure there is a way to do it. I have a pulsed voltage output from my measurement circuit and so far I am capturing the voltage. Can someone suggest a way to convert these voltage pulses to an RPM value. I am sure some type of leading edge counter would work.
    Thanks

    Not the cheapest route but there is a SCXI card that measures frquency.
    http://sine.ni.com/nips/cds/view/p/lang/en/nid/1661
    There may be some other frequency cards this is one I have used in the past.  With this card you can create a virtual channel and ask it what frequency the analog signal is going into it.  From here there is a conversion from frequency to RPM depending on the type of resolver or hall signal you are using to generate that signal.
    This method is the easiest but the cheapest would be to get a cheap AI DAQ device that can measure several times faster than the generated signal (nyquist theorem) then analyze the series of AI reads to determine the frequency.  Then convert frequency to RPM.  Depending on the signal a USB DAQ device might work, if not a PCI or PXI + MXI card would still probably be cheaper than the SCXI route.

    what can in do?

    Well unfortunatly that advice does not always work. I bought a unlocked iphone4  from apple several years ago and went to att on a no contract basis. Six months later the phone crashed while updating the operating system. Apple replaced the phone with a new one. All is fine till I got a iphone5 and gave te phone to my cousin. The phone is now locked to att but att says the IMEI number is not a valid ATT IMEI and therfore cant unlock it. Apple says there is nothing They can or are willing to do so now I am stuck for a 600.00 phone that can't be used.
    If anyoun knows a way naround this situation mI would appreciate a heads up.

  • HT1904 block using credit card

    I don't want to use my credit card how do I block that information out from this user using my card ?

    Usually, where there are discounts on offer from Apple, a credit option from Apple would not be available.   As with many businesses, it is usually one or the other.   Go to Apple on line  http://store.apple.com/us  and click on the flag, bottom right, select your national flag, then read about the current offers there.   As I mentioned, you can use your Credit card, subject it is acceptable, and usually repay monthly in part or the whole.
    Thank you for the star.

    Using a debit card in any online service where it stores your card is a bad idea in any case since if someone gains access to your account in the service, they can quickly drain your bank account. Credit cards limit your liability, as do prepaid iTunes cards.

  • Measure current and voltage in Elvis and labview

    Hi!  We're setting up a control system setup for class where we need to monitor the current and voltage that we are supplying/drawing from the ELVIS hardware within a LABVIEW setup.  So far, we can accurately display voltage input and outputs from the AI and DAO terminals respectively.  However, we can't seem to find a direct way measure current draw.  I believe that we are supposed to be able to get DMM readings from the AI5 channel, but either we're not doing it correctly, or we still need to place a known resistance across it (which we cannot do, due to variable loads).  Any advise please?
    Cheers,
    Gerald

    Are you using Elvis I or II?  From your post, I will assume it is Elvis I but please correct me if this is not the case.  Page 38 of the manual shows that ACH5 is used for capacitor or diode measurements for the DMM.  To measure current, use the connectors on the front of the Elvis unit and then route the current HI/LO on the protoboard to either the oscilloscope or an analog input channel.  You can use the DMM Soft Front Panel to monitor current as well.
