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.
