Hello,
I have a working VI to access a Keithley 2410/2010 multimeter and export the readings to an Excel file. I have a new Keithley 2750 Multimeter that is not compatible with the VI. How can I alter this VI to work with the Keithley 2750 for the exact same readings? Attached is my project. Thanks.

Hi siemonco,
Follow this link to download the driver for your Keithley 2750.

Once you have this installed, you should have a new functions palette in LabVIEW available for your new device which you should be able to configure in the same way you have in your old VI. If you are unable to figure out how to configure these new functions, most instrument drivers come with examples that are a great resource. These can be accessed under the Help»Find Examples»Hardware Input and Output»Instrument Drivers»lv Plug and Play. Hope this helps.

Thanks for posting, this was a great help. I had a question making some adjustments to the program so that you could take resistance measurements every 10 minutes using the 4 wire configuration over a period of a few weeks. Can you provide any guidance on adapting the program? I'd appreciate any feedback.
thank you

Did you download the instrument driver yet? Unzip it under the folder "instr.lib", under your LabVIEW folder. Restart LabVIEW.
Now if you go and open a VI, go to Help --> Find Examples. Here type the word "Keithley" in the search field. Hit Enter. You will find several example VIs how to use this driver pack...

Yes I went in and found the examples and was using the Keithley 27xx continous multi read, but what I'd like to do is take that and add in a way to pull measurements every 5 minutes. this would go on for a few weeks and export to a note pad file using the to write to measurement file express VI, I'm just having trouble finding a good starting point. If I were to lose power would all the data be saved up until lossing power?

Hi Dennis,
I'm able to pull the data and send it to a measurement file my issue now is that I cant get figure out how to intergrate the elspsed time so it reads every 5 mins, the screen shot be low, I assume the shift registers should be remove (highlighted) I've also had issues going from the read data buffer subset vi to the elapsed time express. I've done some tutorials but still having issues. appreciate any help you can give.

So, this is what I ended up with, do you know if there will be issues if I have to use a rs232 db9 to vga adapter to run on a laptop without an rs232 db9 port?
