Part 23: Multi potential step method (STEP) & Multi current step method (ISTEP)
1. Multi potential step method (STEP)
The multi potential step is repeated with 12 potential steps applied. The current is recorded as a time function. The figure below shows the potential waveform applied as a time function.

Fig. 23-1 STEP potential waveform.
2. Multi current step method (ISTEP)
The multi-current step is repeated with 12 current steps applied. The potential is recorded as a time function. The figure below shows the current waveform applied as a time function.
