Resistance measurement using Keithley 6517B

[ponty2007]

Hi 

I am trying to measure the resistance using Keithley 6517B. I have modified the example that I downloaded from the NI driver page and added a voltage source in the code (I need to measure the resistance at a specific bias). I am new to LabView and I have come across several issues:

1. The code does not show the current measured value, instead it shows the value from previous measurement. It seems that I cant reset the buffer.

2. I would like to do 10 measurements with an interval of 10s and store the data. I guess a For Loop would be the best option with an a delay function.

I would greatly appreciate if someone has any feedback to resolve this issue.

Instead of marking "figured it out" as solution it would help others to provide a real solution...

Hi, 

I also have issues trying to measure resistance with a Keithley 6517A using the labview driver (with labview v2013)

When I use the VI Keithley 6517 Acquire Measurement.vi the instrument never enter in OPER ON mode (no output) and I get an error 230 "stale data"

I tried to write a VI that kinda work, except not always and I don't understand why:

When I use the SENS:DATA:FRES? I understand that I should get a new measurement from the instrument, but this doesn't happen, and I get a timeout instead + error 230 stale data

If I change that part, and use a READ? command, then I get a correct measurement.

What is the difference? Could somebody explain?

Thanks
