continous current measurement using keithley 2400

[JohnChae0929]

Hi,

I'm trying to create a LabVIEW program that can continuously measure current. https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x37XCAQ&l=en-US

my code is basically from that website but I have another voltage supply meaning not including the source mode block and using GPIB instead of rs232. The program does pick up something but it is an inaccurate measurement. Any advice?

Here is my labview program. I think i got it to work.

When I run my keithley continuously beeps, is that normal?

Also I want to plot current vs time, any scripts that might help?

The graph im getting is very noising graph 

How do I adjust the scale of the graph so it doesn't look like this?

Another update. I've figure out how to plot it against time and you can see it in the attached files. But my graph looks like this. 

I'm assuming it is because of the beeping of the keithley 2400, meaning it is not continuously measuring it and rather data points of it. Any idea how to fix this?
