Cheapstat stability and sensitivity test

[wendy]

Hi all,

I am supposed to test stability and sensitivity of a newly purchased Cheapstat. I still have no idea what to test to really reflect those characteristics of a potentiostat? Maybe using a dummy cell? I would appreciate any suggestion. Thanks.

@wendy I just designed a little dummy cell for testing a new potentiostat design which we are currently developing. It would work with the Cheapstat as well. I've ordered 10 PCBs - which should arrive in about two weeks. I could send you one if you would like.

You could put different values in for R1, R2, R3 and C1 for different tests.
