CHI660 or CHI760 Electrochemical Analyzer/Workstation

[rimfire44]

I am trying to find anyone that has used Labview to control a CHI660 or CHI760 Electrochemical Analyzer/Workstation with Labview. They have some drivers and examples online but as yet I have not been able to make anything work.

Thanks in advance!

Hi ! Did you search here: https://www.ni.com/en/support/downloads/instrument-drivers.html ?

Have a great day

That is where I got the original examples, but I am running into a snag on a particular aspect of things and I was hoping to find somebody smarter than me that might have figured it out.  Thanks for the tip though!

And the examples are NI-Supported or NI-Certified?

Did you check also those tutorials?

The examples are neither certified or supported. The folks at CHI had a guy that wrote them and then quit, and CHI won't even talk to you about, so they are pretty much orphans.

I have everything up and talking and some aspects of their demo's are working, there is just a particular technique that isn't playing right.  I was just hoping that somebody had played with this thing in more depth.

Thanks for the suggestions.

If is serial you can do a loopback test.

I'm in need and actively working on this now. Did you have any luck? I'm trying to build upon the scraps of code available on github.

Thank you for posting to the forums!

I would recommend making a new post if you are still having issues as this one is a couple months old and typically newer post have higher visibility.

Also it would be helpful to know what specific issues that you are encountering/post the code so that other members of the forum can have a better chance of helping out!

I wish you the best of luck on the project!

I fought it for several weeks and got nowhere. The key to unlocking all the techniques for each model is the ID apparently  I never figured out how to get a proper ID back from each of our machines. All of them returned the same ID, and that particular ID only unlocked one or two of the techniques. I even tried faking out the software but dead ended. I'm a pretty darned good LV programmer and I finally realized that I had to find a way around remote control. 

In the end we managed to drag it out of CHI that the actual signal coming back from the cell is available on one of the DB connectors. So I’ve just been pulling the signal there with a DAQ and analyzing it to get us some kind of automation.   He did tell us how he analyzes things for SWV, but I’m not sure how the other techniques might work. 

Good luck and let me know if you manage to crack it.
