The output current and voltage of the potentiostat increase at the same time, but after lowering the protection potential, the output current and voltage of the potentiostat remain stable. What is the reason?

Generally, the increase is caused by the change of soil resistivity. After adjustment (in a small range), because the potentiostatic instrument itself samples the pipeline potential, so the IR increases, but the pipeline potential is still disturbed by the negative feedback function of the potentiostatic.

Previous:When the output voltage and current of potentiostat reach the maximum, C1 potential indicator drops?
Next:Can a potentiostat be used to measure corrosion? Why also used to measure corrosion, potentiostat is only a few thousand, and electrochemical workstation to tens of thousands?
