keithley 2000 starting channel

[Rimasaurus]

Hi Noam,

One thing you can try is to use a different format, with commas between the channel numbers, to send the (@X:Y) list.  For example, instead of ":ROUT:SCAN:INT (@1:10);", try ":ROUT:SCAN:INT (@1,2,3,4,5,6,7,8,9,10);".  Also, make sure that you are selecting the Internal scan mode in Configure Scan.vi, because the NI Spy log indicates on line 15 that the mode being selected is None.

The attached Configure Scan VI should automatically format the list with commas.  Try running this VI and let us know if this makes a difference.

Regards,

Rima

Hi Rima,

First of all, I use "internal" scan mode. At that time I probably forgot.
Second, where do I make the change of (@1,2,3,4,5,6,7,8,9,10)?
Last, how do I use the VI you sent me? I get an error massage saying that the VI does not belong to the library it is in. (error massage is attached)

thanks,
Noam.

Hi Noam,

Try the attached VI.  The VI should implement the command with the commas automatically.

It says I need LabView 8.5 and I use LabView 8.0.

Is there a way to still use it?

Thanks again...

Here you go, saved back to 8.0

Hi Noam,

Somehow I posted the wrong VI, and I apologize for that.  This is the VI I mentioned earlier.

I tried using it in 3 different drivers which are available in NI site (2003, 2004, 2005). To what driver was this VI written?
All of them gave an error about "Error Query.VI".
Anyway, there is no input selection, only 2 outputs, so I can't put the "intialize.VI" before "configure", and as for the settings, I changed them in your VI itself, I think it's o.k.

The result is that the Keithley starts scanning but never stops and I never get output so I don't know it's influence.

O.K. I understood my mistake. Your VI is just fine and working with 2004 driver.
Anyway, it didn't solve the problem. It still starts measuring from the 2nd channel.

Hi Noam,

At this point, it seems that this issue is specific to the instrument, so it would be best to contact Keithley.  Good luck!
