What factors need to be considered while setting up the potential window for cyclic voltammetry (CV)?

Considering the electrochemical step-up restrictions of Potentiostat/Galvanostat voltage and current ranges, it should be chosen within the instrument range.
Ensure that the potential window covers the whole redox process of interest.
When selecting a potential range, remember the reference electrode potential because electrode-to-electrode potential ranges differ.
The chosen electrolyte must be compatible with the material’s potential range, certain electrolytes may be restricted by overlapping potentials.
To determine the material’s potential limit, perform a CV experiment on the selected electroactive material in the range of maximum and minimum potentials.
Do some literature research and find the appropriate paper similar to the working material.
