Linear Sweep vs. Staircase Sweep
ZIVE
electrochemical workstation is digital potentiostat/galvanostat. This will use DAC(digital to analog converter) to control value.
1. Linear
Sweep
For this mode, Smart manager will apply sweep mode using each one DAC value increment or decrement with time duration. This will adjust DAC value and/or time duration (compensation) to meet scan rate which user defined.
This
function is for low capacitive sample. Do not use this function for high
capacitive sample such as supercapacitor, corrosion, battery etc.

2. Staircase
Sweep
For this mode, Smart manager will apply sweep
mode using constant DAC value increment or decrement with constant time
duration. Smart Manager calculate DAC increment/decrement value nearby step
height(or sampling interval) which user defined and time duration to meet nearby
scan rate which user defined.
User can select averaging sampling condition.
This function is for high capacitive sample
such as supercapacitor, corrosion, battery etc.
