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 E_min/E_max is exceeded.

Parameter Description

Parameter	Name	Description	Unit
I start	start current	starting DC current	A
I step	step current	current of each step for the staircase function	A
I end	end current	maximum DC current of the last step	A
t settle	settle time	settling time at I start before the first V-I step is stimulated	s
t step	step duration	duration of each step of the staircase function of V-I	s
ODR	output data rate	number of measurement points per second note: the current is always measured at the maximum possible speed and integrated for the selected data rate	\(\frac{1}{s}\)
E min	min potential	minimum potential limit for premature staircase determination	V
E max	max potential	maximum potential limit for premature staircase determination	V

A Start Phase Galvanostatic can be enabled or disabled before the method is executed.

Measurement Result

The voltage and current curves are recorded as a function of time. Additional measurement signals are also recorded when activated.
