How to make a multimeter in multisim using LabVIEW

Hello there, I want to make a multimeter in Multisim using LabVIEW. And I have read this article http://zone.ni.com/devzone/cda/tut/p/id/5635#toc3 before.
And now I have these questions:
1. How to measure a resistor? The Impedometer.llb in lvinstruments folder made me confusing.
2.how to measure the current? I can measure the voltage but I dont know how to measure the current.
3.What's the meaning of "instrument version" in every _multisimInformation.vi, whether I can modify it?

Hello,
A question for you: your multimeter will acquire real data (using a data acquisition board) ? or, is it just for simulation (like the Multimeter included in Multisim)?
The Impedometer.llb is a library that contains all the files for the Impedance Meter instrument in Multisim. As stated in the template, the instrument version constant is an internal reference that must not be modified.

Time Capsule only works for one device at a time, how to make it capable to be used for multiple devices at times

Time Capsule only works for one device at a time, how to make it capable to be used for multiple devices at times.
Please help to set it up, thanks in advance

You need to give more info..
Firstly only works for what.. networking.. backup.. wireless. You need more nouns.. more adjectives... describe what you want and what fails.. then we can figure out why.
Most likely you have bridged it when it should be in router mode..
Most likely you are using Lion or ML which has the airport utility bridge the TC by default.
Change it to working as a router. That might help.
If you press reset button it will default back to router btw.
If you are on Lion.. use a real utility. http://support.apple.com/kb/DL1547

Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.

How to write the data into EEPROM using Labview?

How to write the data into EEPROM using Labview?

You would need some sort of EEPROM programmer. Typically might
communicate with it via serial. I don't know how you would do this in
LV. You would need to have the command protocol for the programming
device to start with.

Does anyone know how to comunicate with a USB port using labview 6?

Does anyone know how to comunicate with a USB port using labview 6?

Unfortunately, there is no way to communicate directly with a USB port before LabVIEW 7.0 and VISA 3.0. With the new releases, there are functions called "VISA USB Control In" and "VISA USB Control Out" that give you direct access to a USB port.
You can definitely communicate with DAQ, Serial, or GPIB devices that are connected through a USB port, though. This is done seamlessly through the NI-DAQ, NI-Serial, and NI-488.2 drivers.

How to make a call in j2me using bluetooth?

Hi All,
I wanted to make a call to another device which is in my bluetooth range i wanted to know how to make such a call?And i have heard that using bluetooth for making calls we can only do half duplex communication that is at a time only one person can speak while the other hears ?I wanted to know that can we do a full duplex communication also so that both of them can speak as well as listen at a time.
Thanks

To make a call using javax.microedition.midlet.MIDlet.platformRequest().
for eg:
String telNo = "tel:+9682651761543";
platformRequest(telNo );

How can i design a smart antenna using labview?? plzz

i have my final year project. I am student of Beng in Telecommunications. How can i design a smart antenna using switched beam algorithm on lab view??

You can hardly use LabVIEW to design antenna, but definitely can use LabVIEW for Characterization, Optimization, and Test your antenna design.
Hope you got the point here.
I am not allergic to Kudos, in fact I love Kudos.

Is it possible to make a Frequency Domain Reflectometer using LabView? For waveguide frequency measurement?

Hi everyone
I have a tricky question that I have looking around for the answer but couldn't find it!
I want to know if I can build a Frequency Domain Reflectometer (FDR) to measure frequency return in waveguide. Telecommunication engineers would understand what I mean! It a bit like TDRs but its frequency instead of time.
I would like to build a Frequency Domain Reflectometer using labview application, how can I do that? What sort of code do I need and what equipment do I need to operate with the NI code?
Please give me the chance to thank you all very very much for your help and support and for looking here,
regards
Fezz

Hi Fezz,
I am not familiar with using FDR systems but know there is a good example of producing a TDR in LabVIEW available on the community. This might provide you with a base and a grasp of the architecture you could use to create the functionality.
Time-Domain Reflectometer (TDR) Example
Regarding the equipment you would require to achieve this I strongly recommend contacting your local NI office who will be able to adviser you fully as this will depend upon your desired specification.

You could just use Copy File. It would be a lot simpler than reading the file and appending to your second file every second.

How to create a dataplugin for DataFinder using LabVIEW

We want to use LabVIEW to create a dataplugin that will be used by DataFinder (My DataFinder). We have found on the NI web site the LabVIEW DataPlugin SDK - , a SDK that allow us to create a dataplugin. The SDK is for LabVIEW 8.6.
The dataplugin example code of the SDK work very well in the “For testing” section of the development project. We are also able to register it to use it through DataFinder. The dataplugin is available in the “Configure ...” window of DataFinder.The problem is that the dataplugin doesn’t work with DataFinder. We didn’t receive any kind of error message or code. We only get the value “eIndexedFailure” in the “Index status” property. After expectation, it seems those input parameters are different between a LV and a VBS dataplugin. And we think that can be the source of the problem. There is someone that can help us about that?
We also want to use LabVIEW 2009. The SDK example work under 2009, but we get the same problem with DataFinder.
Thanks
Solved!

Dear Kelly R, you're right I can’t open the file in DIAdem. The RegisterLabVIEWDataPlugin.ini file is correct. But I’ve just tried to rebuild the project and then use the Installer instead of just using the Deploy. Now it works, even with my own code. Now I can open the file in DIAdem without problem. The installer uses the “NI LabVIEW Dataplugin 1.0” package. It seems that the SDK installer has never install this package.I thank you all for your help.

How do I establish serial communication using LabView to two stepper motors using a motor controller?

I currently use an off the shelf motor controller to run my two stepper motors. It already has integrated a firmware software that sends commands to operate each motor. I would like to create an interface where I can send these commands using LabView. If someone can point me in the right direction I would appreciate it.

Look at the examples for the serial VISA vi. Something like Basic serial write and read.vi is a good starting point.
Have you searched for a LabVIEW driver at the NI LV driver network? Asked the vendor?
If you write your own driver with the serial VISA vis remember to open and configure the port only once at the beginning and close it at the end of your program.

How to control yaskawa varispeed F7 VFD using labview ??

I want to control the frequency of VFD (Yaskawa varispeed F7) using labview.
The vi should be like I can know the current freqency and able to change it.
What are the possibilities???
Please reply.....
Thanks & regards
Naren

The yaskawa driver has the registers tables in Hexadecimal, i map them in decimal in labview with an offset of +1 so:
to access register 2h -->        02h = 02d = 400003
                           17h-->       17h = 23d = 400023
I read and write to this registers:
To control (RUN-STOP-REVERSE)       01H = 400002
To set freqency                                   02H = 400003
To monitor (at_zero-run-reverse)            11H = 400017 addressed by bit 400017.1(at_zero);    400017.2(run);       400017.3(reverse)
the registers i cannot read are              26H = d38   to read the frequency
                                                         27H = d39   to read the ouput current
                                                         28H = d40   to read the ouput power
I have tried with all instructions (000026; 300026; 400026) even with the array option and i still cannot read them.
