| [1] The dynamic range is the range that can be covered during a single scan within the full potential range. For example; a linear scan can start at -1.5 V and end at 1.1 V or vice versa, covering 2.6 V dynamic range. [2] The compliance voltage is the maximum potential between Working and Counter electrode and depends on the selected mode.
