Ok, so I've managed to test a different Rodeostat and a different Dummy cell.
Here are the result:
Second Test result

Any idea what could be causing such difference?

Hi,

I've been getting unexpected values for my tests with Cyclic voltammetry with SPEs. I moved back to a dummy cell to start from a known point but I'm getting strange results. My current appears to have opposite signal and I'm not sure why.

I can't be 100% sure, but as far as I remember, I was getting fine results before having to update it. Re: Python error

Also, it seems to me I'm getting a lot of noise. Here's the image from my test with a dummy cell.

Blue line = input potential
Orange line = output current

Test result

Is this correct? Any suggestions on how to deal with noise besides filtering?

For the SPE, I'm using the connector sold on iorodeo store, but it's loose. I'm might be having contact issues. Any suggestions on how to solve it?

Hi, @austin ,

I followed all your steps and it worked perfectly. Thanks a lot!

Thanks, @austin , I'll try that. Weirdly, I haven't done anything with the firmware. Any chances this could be due to a damaged cable between the my PC and the Tensy?

Hi @austin ,

I'm having the same issue with two of my potentiostats from Windows. Where exactly is the Tools>Optimize you have mentioned?

Thanks

Thanks, Will. That elucidates a lot!
We are concerned with the noise, but we'll have to try it first.
I'll buy one for test and see how it goes.

Thanks again.

Hi,

I'm thinking about using Rodeostat for my project, but I'm not sure if it will fit.
We need to read:

• Maximum Currents of 200uA; (from the page, the Rodeostat can read up to 1uA, correct?)
• Current ranges of 10nA to 200 uA;

Is it possible? How's the Potential Accuracy and Precision? How's the Current resolution?
If not, could it be modified to cover those specs?

Thanks!
