Staircase Galvanostatic

In staircase galvanostatic measurements, a current scan is performed using discrete current steps with a constant step height.

The potential and current are measured over time at a defined sampling rate.

The galvanostatic staircase can be terminated early if a defined potential limit Emin/Emax is exceeded.
