Agilent 34970A how to measure current and temperature simultaneously via 34901A

[Dennis_Knutson]

Fine but what is the actual scan list?

for temperature 101 and for the current 121

Okay, that seems fine and by looking at your code, it looks like you did the modification correctly. At the moment, I only have access to a 34980 and not the 34970 so I cannot run the code. What you might do is set some breakpoints and step through the code to see when the instrument is throwing the error. Also try setting one and then the other channel list to be empty so that only one function is called.

Can you run any of the other examples? The EZ Scan allows you to select a current measurement. It does it slightly differently so it would be interesting to know if that works.

Thanks your support. I am in the same situation too here. I am out of office and I have no chance to access to my 34970A till friday due to my personal stuff. I run other examples. They works well and also I made basic temperature and pressure measurement programs that I need. I attached them below. They works pretty well. But I cannot combine these two programs into one program.

Hi Egemen,

I only see this discussion yesterday evening and  you have probably resolved this issue, but I made some modification to your code. If you can give it a look and tell me if it is usefull for you.

Bye,

Lamberto

Hi Lamberto,

Thank you for your interest. But I cannot open the VI, because I have labview 2009. Could you send it available for it for me?

I solved the problem a long time ago, but I forget to mark as solved. I want to see your modifications on the vi too.

Hi Egemen,

I'm sorry, but I'm not aible to do that, but you can see in the attached files your block diagram and my modifications that consists only to put in serie the blocks you have put in parallel.

Hi every one, 

I am using Labview to control Agilent 3210 and I got an error like this : Error -1073807346 occurred at VISA Open in ag33xxx - Initialize.vi->ag33xxx - Arb - Application.vi . Would you like to help me to figure out the reason why I got it? Agilent 3210 and PC are connected by USB. 

Thank you very much.

I do not know that error but searching on the net and come across this one. Maybe it will help you.
