Galvanostatic Mode ECN Purpose

An Electrochemical Noise test in galvanostatic mode measures current noise at a fixed electrode-potential. A specimen is immersed in a solution and a constant current is applied while measuring its potential (versus a reference electrode) in a three-electrode experiment.

Galvanostatic Mode ECN is useful when you are modeling the surface fluctuations that affect the charge-transfer processes of your system at a steady-state current. ZRA Mode ECN cannot test this type of system.
