I was trying to do RRDE experiment using Gamry. I appiled 1.2 V vs Ag/AgCl at the ring and 0 to -0.65 V vs Ag/AgCl at disk . The potential at disk keep stuk at around 1 V and does not go over the selected range. When I stop ring collection then I works well. I also tried two electrode system to see if it is an issue fron reference, but it's not. When I change potential at ring to 0 vs Ag/AgCl , I can see the potential running from 0 upto -0.2 Vs Ag/AgCl in disk. And Also doing only LSV at disk give me data. But the CA overload problem occurs only while I try to do ring and Disk together. I also calibrated both of the potentiostat.
Thanks for helping.
