Can anyone please share the LabVIEW code to get a voltage vs current plot for a resistor by Keithley 2460?

Hii all,

I am new to LabVIEW, Can anyone please share the LabVIEW code to get a voltage vs current plot for a resistor by Keithley 2460?

Thanks in advance.

Reshna.

Dear Reshna,

90 % off all forum question here are answered with the same:

Be more specific. You are too vague. At what stage are you now?

In your case:

Measurement or simulation? If measurement, how do you measure it? Do you need help selection NI hardware for that purpose? Do you have already specific hardware? What kind? C-series modules? myDAQ? Sensor with RS232? What is the voltage range? Single measurement, series of on demand measurements? How do you want the code around data acquisition to work? Or you already have analog waveforms in LabVIEW and is your problem only related to correct visualization?

And I am absolutely sure that noone will create and share the LabVIEW code for you. You will code and the auditory here can advise. I can only recommend LabVIEW examples which cover most of the basic engineering topics.

Sorry for not explaining correctly. I have already posted one question regarding the error I was facing using one LabVIEW code, but could not solve  the issue from the suggestions, that's why I posted again...

I am using Keithley-2460 for source voltage sweep and measure current (USB connection is used). I wanted to get the voltage versus current plot for a  200 ohm resistor. I have modified an example code for getting voltage, current wave forms and that's what I am using now. This one was for keithley-2450. I have installed 2450 instrument driver since it was suggested okay to be used for 2460. I am using a two wired connection and I am getting an error of "No readings exist within buffer" for both example code and modified code. I have tried different ways like changing the compliance level, waiting time for operation complete etc. and could not solve it. Keithley is showing V-I plot correctly in its monitor. I am attaching both codes, the videos of running the code and images of set up ( can be seen from the google drive link). Please have a look at it. In the original code and modified one I am facing the same error. Could you please help me out...

It seems to be problem with the library. Do you have some example VIs included with the library? Have you ever been able to get a reading? Just a basic one, i.e. set a voltage, measure response.

I was able to get the V-I plot with correct current values by using a very high resistor 10 mega Ohm, but while using 200 ohm or resistors in kOhms  I am getting error. It seems like low impedance values have the problem. I have tried with four-wire sense mode also, but was getting same.
