Keithley 2450 4 wire resistance measurement



I'm a student who study at material design lab in SKKU, Korea. 

I'm new in labview program.. I want your advice.


I want to measure 4 wire resistance measurement with bias current input with Keithley 2450. 


I downloaded driver.  


This is the whole VI, 

I used sub VI a lot because I need to use in another code.







I notice I have to use "Enable Remote Sensing"  - after that "Enable Output" from searching. 


But when I run the code and look at the front panel of Keithley, it shows two wire mode, measuring current, input voltage.. 


What component should I adjust?

Not sure if this will help but here is the pertinent part pulled from one of our routines.  I don't see anything obvious for order of operation that would cause yours to not work, but I don't have direct access to the hardware currently to test it out.

thanks for reply. 



I build this VI again, but it gives

2 wire mode, resistance measurement, input voltage. 


I have no idea what sub VI can set 4 wire mode... 

Did I miss something?

I found that if I do in this sequence, it can measure


input current / 4 wire voltage measurement mode / voltage output 



when I use Keithley program to measure sheet resistance, it measure resistance using 4 wire voltage measurement mode. 

So I guess using 4 wire voltage measurement mode is right, but I don't know how to make output as resistance ( ohm unit ).. 


Do you have any solution for this..?

Check this old thread. It is also regarding 4 wire resistance measurement using keithley 2440. It might help you.

I want to measure 4 wire resistance measurements with bias current input with Keithley 2450.

I downloaded a driver that gives an error.

I could not find the relevant driver. can you help me? send me the download link for the driver 4 wire resistance measurement.
