i WANT TO READ DATA FROM A MULTIMETRE USING INTERFACE RS232 HOW TO DO

[KRAKOW09]

I would like to read data from a multimetre using an interface RS232 with labview. it is for a lesson and I dont know how I could start with this. could anyone help me? It is only something virtual, because I dont have the Multimetre. Thanks in advance

Buenos dias,

Utiliza drivers Visa ( se encuentran en una carpeta con el mismo nombre, pon VISA en el buscador de LabVIEW).

Con el Write escribes los comandos que quieras al multímetro, con el read lees los datos que quieras.

Otra opción mucho mas facil, si dispones de drivers para el multímetro introduce la dirección RS-232 en LabVIEW en el Handler (seria esta algo similar a COM 2, COM 3 ...etc dependiendo el puerto utilizado en el PC).

Faltaria un configurar del puerto serial (pon "Visa configurer serial port").

Vaya bien !

Hello,

You will need the NI-VISA driver to be able to communicate with your serial port, which can be found here http://joule.ni.com/nidu/cds/fn/p/sn/n23:1640/lang/en

I'd suggest downloading the driver, and taking a look through the various examples we include. One in particular you may want to take a look at is Basic Serial Write and read.VI

Hi, thank you very much indeed for the replays. I would like, if it is posible, if you have some practical examples about programs which read some information from a multimeter, I have a multimeter at home... and I have some mesures in it... and i would like implementing a program to read that information. do you have some examples??? i give you my e-mail address if you could send me some of them... Thank you so much for your help, you can replay me in spanish, I understand.

Que modelo y marca de multímetro tienes?

Hello,

I would reply in Spanish, but it probably wouldn't be very coherent 

As far as examples go, I would recommend looking through our various Serial examples (Basic Serial Write and Read.VI and Advanced Serial Write and Read.VI are probably a good starting point). We don't really have any specific examples that I'm aware of that communicates with a generic multimeter. If your multimeter is IVI compliant, we do have IVI examples in our NI Example Finder under Hardware Input and Output -> Instrument Drivers -> IVI. You may want to check our Instrument Driver Network to see if we have any drivers for your multimeter as well.

Aqui puedes encontrar los drivers que tenemos para multimetros en LabVIEW. Y si no tenemos el driver para tu modelo puedes solicitar un driver.

Hi again... thanks to all of you, you are very kind, I have escort 3145A, i dont need drivers... because i can conect it and my computer detects it, what i want it is only several examples in labview program, to read.. for example some data from the multimeter like for example... volts... or Hz or amps...

I only need .vi files, i mean examples in labview. i have the rest hehe. I only need to understand how it works with examples... how the program reads data from a multimeter... i have an example but i need more hehe xD.

Thank you very much in advance... you are very kind to replay me.

Regards

Los drivers que se encuentran en el enlance en el post anterior son instrument drivers que contienen generalmente ejemplos y VIs que contienen varios commandos para communicarse con los instrumentos a distancia.
