Labview VI's for keithley 617 meter

[VamosRafa]

thank you very much, now it works correctly, the problem was the number format inside the driver.....

Now I have another little problem, please don't hate me..... I made a for loop and now I can read correctly the resistance value for N values of Voltage (using V/I ohms function). If instead I do the same with Amps function I get a bErr (bus error).... why??? what I have to change??

Sorry my labview is 8, I took for 2008 😛

Hi Vamos,

again I can only advise to do some debugging! Do some step-by-step debugging to explore the wrong commands and to know, at which position the 'bErr' pops up. Then open the Keithley manual to read about the command resulting in that error - they probably also mention reasons for that error...

Hello...

I'm relatively new to Labview and Instrument control.  I have a Keithley 617 electrometer and have downloaded the attached VI.  It seems to work okay; however, I don't understand why the VI stops running and don't understand the overflow indicator.  What does that mean exactly? 

Also, I want to be able to read/write the signal 5 times a second for 10 minutes and cannot figure out how to do this. 

Thanks

You really need to take one of the LabVIEW tutorials to understand some of the basics. Quite simply, the VI is written to only run once and then stop. In order to keep running, you need to create a new VI with a while/for loop and call this as a subVI. I have no idea what you mean overflow indicator. The VI has no such thing.

After the tutorial, you should have a better idea how to run a VI for a fixed amount of time. Whether or not it will run 5 times a second is questionable. There would be several changes required to eliminate the setup being done with each call of the VI. When someone says they cannot figure out what to do, the smart thing is to attach the code to see what has been tried.
