• How to display the voltage and current of synchronously

  Recently, doing a project on the acquizeing voltage and current synchronouly, then display. the design is welding a resistor(1%) 0.5 ohm in NI 6251 entered analog of her HAVE differential, then acquired the differential voltage at the input to convert current. At the same time, I hope to recover the path of analog input voltage. My problem is that the current profile data. Please help me .the program screenshot is show below. ---1. Perhaps you ask why not use no. - a way to get voltage at all port of AI, then in the use of the software less to get a voltage inputs HAVE. in this way, my problem is solved. I try, but the current accuracy is failure. because my current range expect is 1uA ~ 100mA. precision current samll won't be promised if you use simple ways for granted NOR 6251 voltage.

  Use a waveform graph.  Graphics keep history, you do not have to accumulate the data.  He does it for you on the screen.

  2. What is the minimum unit of identification of the TSC103IPT amplifier? I doubt that the 0.5uA can be identified? (0.5uV = 0.5 ohm * 1uA) Because I can't find anything on the auccary in TSC101IPT datasheet.

  The amplifier is analog.  Thus, he can win anything.  But you should really think about a higher resistance if you really want to measure this small of a current.

• Chroma DC power supply RS232 communication (read problem of over-voltage and current)

  Dear all.

  I chroma programmable DC power. Based on the programming of the Instrument manual I develop using RS232 communication. Based on the program I can set the voltage, current, over-current protection, protection against overvoltages and make IT / OFF out put supply perfectly.

  But I have to read the measured values of the output power as current and voltage. Measured applications are the voltage and current of the output of the power supply. My problem is two of them read at the same time. Currently, the reading is only voaltge or current (if the first request is v? it is voltage read out but no reading for the current) and if the first request is CURR? the reading for the current, but not for VOLT? The status message is OK, even if it is to read values.

  Thanks in advance

  What I see in your program, it's that you do not use the stop for reading character. For your writing, you do the hard with all these concantanate string functions. You can set the stop character for all entries with a node unique propert - "ASRL end Out.

• calculate the symmetrical components of voltage and current

  Hi all. I work on the calculation of symmetrical components of voltage and current in Labview. I have included the relationship between the symmetrical components and sequence as photo 1 voltage. I'm going to use this calculation for several times, so I wonder if anyone has some ideas far better bc I wired just so much together to realize the expression. It seems aweful. Any suggestion? as built-in function to achieve this function? Thank you

  Let's take a look on your form (you don't say what is complex, etc, so modify as needed)

  

  For example, here is how you create the matrix A to an alpha given.

  

  Similarly, you can create A ^(-1) matrix (your definition of A and A ^(-1) seem incompatible, otherwise you could just pick matrix inverse of A). After that, you can multiply with you V123 vector using AxB.

• Variables for voltage and current on each component (for use in graphically the diagram)

  Hello

  I have a very simple circuit containing only a source of AC voltage and resistance of two series.

  I want to draw the voltage of the source and each resistance. I can't find any variable involves pre right now, I know I und came to the value of the resistance.

  for example

  UR1 = I * r1

  USource = I *(r1+r2)

  It's pretty boring... especially because that put in square brackets does not work.

  probably the cause variables containing itselfes media.

  hope you have an idea

  THX

  Hello

  The way that you have set in place now of things is correct. Multisim, as well as most of other circuit simulators, monitors the node voltages, no voltage drops. When you draw your diagram, Multisim assigns numeric node names to each node. That's why you see v(1) and v(2) and not something like V (R2). To find the voltage drop in R2, you will need to calculate V (2) v (1). To know the name of each of your nodes (also called threads), simply do the following:

  1. Click Options > properties sheet
  2. For option Net names, select Show all
  3. Click OK

  To make it easier for you, you can name a few nets to something that is easier to read. You can do this:

  1. Double-click on the net you want to rename (the net is the wire you drew connecting elements)
  2. Enter your name, preferred net in the space provided
  3. Click OK

  Hope that answered some of your questions.

• 6009OEM output voltage and current

  Hi all

  Just try to make sense:

  http://www.NI.com/PDF/products/us/20043762301101dlr.PDF

  Page 3 says: high output voltage (push - pull, I = - 8.5 my) = minimum voltage 2.0 v maximum voltage = 3.5V but where can I find out what current can it provide and continue to produce an output voltage more than 4.2V?  (4, 2V is the worst case for the high threshold of logic of a chip, I want to control).

  Thank you!

  J

  Hello J,

  As you mentioned is the maximum voltage of 3.5V when you have a high output voltage (push - pull, I = - 8.5 my). If you need more than 3.5V then you might need to change to an open-drain output. As you can see from the link you provided that you would receive a maximum voltage of 5V.

  If you do not use an open-drain output you have to combine with a pull up resistor.

  I hope this helps.

• Venue Pro 8: use the charger with a little more voltage and current?

  I just bought a Dell came Pro 8 tablet used running Windows 8.1. The seller didn't have the original charger, so he gave me a 12W of Apple loader that had taken out nominal 5.2V and 2. 4A

  Is it okay to use this charger for my Tablet? Any potential problems in the long term?

  Thank you!

  I'm sure that the voltage is OK to 99.9%.  The extent of the current note goes, which is often misunderstood.  The rated current for a charger power or power is the maximum that the charger/power is able to provide. It could be evaluated to a zillion amps, but the equipment to which it will draw only what it requires.

• How to measure high voltage (60-70 v) and current (75-80 a) using a DAQ PCI or USB DAQ

  Hello

  I work with a system that works on about 5kW. The output of the system voltage can go maximum up to 60-70 v and thus the corresponding current around 75-80 a. I have 10 these systems that I want to read one by one continuously for long periods.

  I am designing the automated system best suited for this and looking for the best material that would be appropriate for this purpose. Looking for options, I found that an SCC - A10 attenuator may be used to get the tension down by a factor of 10. But I'm confused, if the high current will pose a problem and also how to measure this high current.

  I need to measure the voltage and current at the same time. Please suggest what would be the most appropriate fitting for the same (preferably PCI or USB)

  The hope of a quick response. Thanks and greetings

• How to put a tension and a delay for a tenth of a second and then record current?

  I use KE 24xx Sweep and measure VI and I added a measure of writing to the file.  However, I would like to pause for a few moments after that he sets the tension before it saves the current.  I don't know how, where, or what to insert.  Any ideas?

  Well, whether or not correct you the data stream, it there's no way that a delay function will put a wait between the voltage and the measurement of current. You use a built-in scan function and the delay before the measure is part of the setting of the instrument and does not part of your LabVIEW code. If you want to use the scan function, read the manual to see if the instrument has a delay setting. If so, you can make an entry VISA and send the order. If it is not the case, you will have to give up the built-in scan function and create your own ramp (i.e. Ramp.vi) and make an individual writing of tension, the delay, the current read in a loop.

• Define independent for rpm and current control

  Hello

  I need assistance with labview. I am able the current, voltage and rpm of a pump connected to a control box. The control box is also connected to my DAQ. My requirement is that I would like to monitor the blood and fluctuations in current on an in labview waveform chart, once I run the file vi and monitor the number of laps when I start the pump. When I try to run the file vi before the pump starts, I get an error code "200284. I understand that the RPM in my vi counter does not receive signals and ends the program. How to set a control sparate for the display of the voltage and current regardless of whether if the pump is started or not? or how to set a control to monitor RPM display only when the pump is started and does not affect the voltage and current display part of the VI.

  This may seem a bit complicated! Please give me your suggestions on how to do this!

  Thank you

  Rajesh

  Looking at your code, the DAQ Assistant on the background is taking in the RPM data you are looking for. You can do a right click on the arrow to the left of the option "timeout (s)" at the bottom of the DAQ Assistant ExpressVI and select Create > Constant. This will create a constant within seconds that represents the DAQ Assistant time-out on entry. You can base the number on how long it will take the number of LAPS to enter to start.

  .

  It should look like the above, but you can change the time that the ExpressVI will wait for your needs.
